WAR DEPARTMENT,
Washington, April 20, 1942.
FM 9-10, Ordnance Field Manual, Ordnance Field Mainte-
ance, is published for the information and guidance of all
concerned. It is based on the fundamentals of ordnance serv-
ice contained in FM 9-5 and the pertinent Tables of Organ-
ization.
The purpose of this manual Is to present a coordinated and
complete picture of the problem of ordnance field mainte-
nance, together with a logical solution of that problem.
While this manual will be found to be helpful as a reference
for operation of the maintenance organizations in garrison,
it is intended primarily as a guide for use in field operations.
There are included in the various parts of this manual a
complete discussion of a typical ordnance field shop and a
method of conducting operations; a discussion of details per-
taining to a typical maintenance company; and discussions
of particular problems in ordnance field maintenance as they
are encountered and solved in particular echelons such as
the various types of divisions, the armored force, etc. Except
where obviously necessary in the interests of uniformity
throughout all ordnance service, it is not intended that this
manual shall impose unnecessary restrictions on the imagina-
tion and initiative of ordnance personnel responsible for the
operation of the Units covered by this manual. On the
contrary, it is intended that the thoughts and imagination of
such personnel will be stimulated to evolve more satisfactory
solutions to the problems of ordnance field service.
The organization of ordnance maintenance in the field
army is based on the principle of progressive increases in avail-
able maintenance facilities from front to rear. The equip-
ment and personnel assigned to each echelon are designed to
carry the normal load of that echelon plus a certain peak load
of the subordinate echelons.

The diagram on page IV illustrates the relation of various
echelons of maintenance in the field army to each other. The
specific assignments of each type of ordnance company will
be found in FM 9-5.

DEFINITIONS
■ 1. Definitions. — a. Axis of supply and evacuation. — A prin-
cipal route following the main line of advance over which sup-
plies are brought forward to the troops and over which dam-
aged and salvaged materiel is evacuated to the rear echelons.
Whenever possible, the axis of supply and evacuation will be
along main highways.
b. Basic load. — The quantities and kinds of parts and mate-
rials carried by an ordnance maintenance unit as initial
stockage for the maintenance of the materiel of the unit which
it is serving. It must be based on the quantities of particular
types of materiel to be maintained, and other considerations.
Basic data for the determination of these loads will be found
in the addenda to the various Standard Nomenclature Lists
(see par. 151) .
e. Collecting point. — In the armored division, an area lo-
cated in the vicinity of the divisional combat units and near
the axis of supply and evacuation (see definition). Disabled
materiel recovered from the battlefield is brought to this area
by recovery sections of the combat units. The location of col-
lecting points Is designated before the units move into combat
by G-4 in collaboration with the D.O.O.
d. Contact party. — A detachment of ordnance soldiers sent
from an ordnance field shop to units requiring assistance.
A contact party may consist of as many men and as much
equipment as is considered necessary for the mission (see
pars. 190-195 incL),
e. Down time. — That period of time during which ordnance
materiel is in the hands of the ordnance personnel undergoing
repairs, and not available to combat units. (See par. 6.)

GENERAL
Paragraphs
Section I. General 2-5
II. Down time 6-11
Section I
GENERAL
■ 2. Purpose. — The purpose of part one of this manual is to
provide a guide for the training of personnel in the operations
and procedure of an ordnance field shop. No attempt has
been made to distinguish between the various field shops.
The expressions "higher echelon" and "parent echelon" have
been used to cover all the various units which might include
ordnance field shops, such as ordnance maintenance bat-
talions and medium maintenance companies. This part
covers in detail the operations and procedures necessary to
accomplish work in, and to maintain the records of, an
ordnance field shop.
■ 3. Planning. — a. Extent of planning. — Shop officers must
continually plan to meet foreseen and unforeseen contin-
gencies. They must constantly study their personnel with
a view to strengthening the organization where it may be
weak, or where losses that might affect the efficiency of the
shop may be expected to occur. They must be alert for
new noncommissioned officer material, and observe the con-
duct and efficiency of all noncommissioned officers currently
holding the various grades.
b. Planning for supply. — The planning required to meet
the future requirements of the shop for spare parts, materials
and tools is a continuing process based on experience. Such
planning merits the thoughtful attention of every responsible
individual in the organization. All personnel should be en-
couraged to give this matter their best attention, with the
end in view that valuable suggestions for Improvement in
technique and provision of supply may thus be evolved.
4
ORDNANCE FIELD MAINTENANCE

c. Maintenance of records (see pars. 36 and 37) . — The
maintenance of simple and complete records is a prime
requisite to the maintenance of proper stock levels. There
Is nothing cut and dried in the problem of the supply of
an ordnance field shop. Requirements of supply will conr
stantly vary. Conditions of service will materially affect
the quantities and types of materials required. Planning
must be continuous and should be based on experience as
nearly as possible. In this connection it is always important
to make a distinction as to whether a replacement of parts
or materials is due to normal deterioration, or is due to
unusual wear and tear. This is important because if the
replacement was made necessary by normal deterioration,
it is not likely that additional replacement will be necessary
on the same major item in the near future. It is likely,
however, that replacements Will be necessary on all other
items of equal age. On the other hand, if the replacement
was made necessary by unusual wear and tear incident to
service, this fact must be made a matter of record as a basis
for future planning for operations of a similar nature.
d. Anticipating future requirements. — The placing of com-
ments and notes on work orders or on notes attached thereto,
such as is suggested in c above and in paragraphs 9 and 88,
are of invaluable aid to the planner who is trying to anticipate
future requirements from a study of past experience. For
instance, it is known that the wear and tear on under-car-
riage parts and tires of mobile equipment is greater in rocky
terrain than in terrain that consists mostly of clay mud;
whereas in wooded country, the action of trees on such equip-
ment is noticeable on bodies and accessories attached thereto.
Rain and moisture cause difficulties with ignition systems.
Extreme temperature changes may cause lubrication diffi-
culties. The effect of different types of action or operation
cannot be known, with consequent expedition of supply, unless
the responsible personnel study these matters.
■ 4. Chain op Responsibility. — As far as may be practicable
the responsibility for each duty should be placed squarely upon
the shoulders of the individual required to perform that duty.
Such individual should not be unduly interfered with, but
should be required and expected to solve his own problems and
perforin the tasks connected with his duty.
5
5-8
ORDNANCE FIELD MANUAL
■ 5. Instructions to Shop Personnel. — Except in emergen-
cies requiring prompt action, instructions should not be given
direct to shop personnel by persons other than those directly
in charge of the personnel concerned. In every case where
instructions are so given the responsible chief should be
promptlj' notified.
Section II
DOWN TIME
■ 6. Definition. — Down time is the expression used to iden-
tify that period of time during which ordnance materiel is in
the hands of ordnance field shops undergoing repairs. Down
time maj' be divided into three phases:
o. The labor time, actually expended in the performance of
necessary repairs.
b. The awaiting-parts time, lost awaiting the drawing or
the arrival of the necessary parts or materials.
o. The return -to-troops time, lost when the organization
to which the materiel belongs does not immediately remove
the materiel from the shop at the time the materiel is ready
to go.
■ 7. Importance of Reducing Down TTme. — Ordnance ma-
teriel is expensive. It can serve no useful purpose When it is
not available to the troops either for training or for combat.
It is part of the mission of ordnance service to reduce to the
minimum the down time for any piece of materiel brought in
for maintenance work. Means by which this reduction may
be accomplished are discussed in the paragraphs which follow.
■ 8. Reducing Labor Time. — Labor time may be reduced by a
study of the best and most expeditious means of solving par-
ticular maintenance problems. It is the duty of all ordnance
shop personnel to study constantly current maintenance prob-
lems with the purpose of developing methods of maintenance
which will result in the saving of time otherwise lost as down
time for materiel. Such methods may take one form of —
a. Replacement of complete units requiring repairs, and
the repair of the faulty unit on time not charged against
the major item.
b. Methods of repair that do not involve the complete
removal of large units from the major item being repaired.
6
ORDNANCE FIELD MAINTENANCE
8-10
c. The development of two or more specialists in certain
types of work such as carburetor, ignition, brakes, etc. (This
method should contemplate the rotation of specialists, in such
a manner as to insure against the concentration of too much
specialization in certain personnel, that is, experts should be
required to impart their knowledge to others.)
d. The development of preventive maintenance procedures,
such as the periodic inspection of ordnance vehicles.
■ 9. Reducing Awaiting-Parts Time. — Awaiting-parts time
may be reduced by careful planning and by continuous, well-
directed activity on the part of personnel connected with the
supply problem. This time may be saved by —
a. Maintenance oi proper records. — The maintenance of
complete and accurate records of parts used (expenditure
records) , together with proper notes covering circumstances
surrounding the need for repair. For instance, notes should
indicate whether the repair was made necessary by road
accidents, night driving, shell fire, excessive mud, rocky ter-
rain, collision with trees, or falling through bridges.
b. Cross-nosting records. — All shop records pertaining to
any work for which material is requisitioned must be plainly
marked with the number of the requisition on which the
material was requested. The retained copy of the requisition
must bear on its face after the proper item, an adequate
notation of the work order for which the material is required
(see par. 93) .
c. Expediting supply. — All personnel in the supply system
must be alerted to the fact that any item on a requisition
bearing a notation W/O No. is needed at once for
current work now in a shop and the supply of the material
must be made as expeditiously as possible.
d. Use of packing lists. — All materiel packed or shipped
from depots for the supply of ordnance shops should bear
on the outside of the package in a waterproof envelope or
other container such that it will not be lost, a packing list,
covering the items in the package.
H 10. Handling of Ordnance Items by Shop Personnel. — All
personnel in ordnance shops should be trained to determine
quickly what items are needed on current work orders, and
to take immediate action to cause such items to be placed
7
10-11
ORDNANCE FIELD MANUAL
In the hands of the personnel responsible for the completion
of the work order. In general, items required for immediate
use on work orders should not be binned or placed in storage,
but should be placed in the hands of the proper shop section.
If the shop section for any reason cannot immediately receive
the items, they should be plainly tagged with the date of
arrival in the shop, the section, and the work order number to
which they pertain.
■ 11. Reducing Return-to-Troops Time. — Time lost return-
ing materiel to the troops may be reduced by —
a. Scheduling ivork. — Setting a time at which the materiel
will be available for release to the organization to which it
belongs, and notifying the organization in order that a rep-
resentative may be present at the time to remove the materiel.
b. Notifying unit. — Notifying the organization to which the
materiel belongs of the time at which it will be available, as
soon as it becomes possible to determine that time.
e. Returning matdriel. — Physically transporting the mate-
riel to the organization to which it is assigned when such
procedure seems necessary or advisable.
d. Folloiv~up. — Instituting a follow-up procedure in each
section, or in the shop office, whereby, when the organization
mentioned in b above is first notified that the materiel is
or will be available, a notation to that effect is made on the
work order or a slip attached thereto. Subsequently the
organization will be repeatedly notified, at intervals to be
esablished by the shop officer, with notations of such notifi-
cation on the work order or the attached slip, until the
organization calls for and removes the materiel.

ORGANIZATION
■ 12. Organization op Shop Office. — a. Purpose. — The shop
office is organized to supervise and coordinate the activities
of the shop, to keep such records as may be necessary for
the efficient operation of the shop, and to perform such addi-
tional clerical work as may be necessary.
b. Personnel. — The personnel of the shop office normally
consists of one officer and a sufficient number of enlisted men
to perforin the tasks of this office. The chart shown in figure
1 may be used as a guide by the shop officer in organizing the
office.
■ 13. Organization of Shop Sections. — Each shop section
usually consists of a foreman, an assistant foreman, and
additional personnel as required. These sections may be fur-
ther subdivided into specialized units as deemed necessary by
the section foreman. The chart shown in figure 1 may be
used as a guide by the shop officer in organizing these sections.

GENERAL
B 14. General. — The general principles underlying the opera-
tion of all sections of the shop will be the same. This section
of the manual is designed to cover all matters pertinent to the
operation of every section. Matters pertinent only to particu-
lar sections will be discussed under the proper sections of this
chapter.
■ 15. Conservation of Materials. — Every effort will be made
to conserve materials. This is particularly true in the welding
section.
■ 16. Shop Police. — Every effort should be made to maintain
a high degree of cleanliness and order in the shop. To assist
in attaining this end, there should be provided numbers of
cans or deep pits in which may be deposited all scraps and
shop refuse. Cans should be emptied daily; pits may be
burned out when the fire or smoke will not be objectionable.
There should be provided a scrap metal bin. All metal scrap
will be thrown into this bin. Periodically this bin should be
emptied. At this time all metals naving salvage value such
as aluminum and other nonferrous metals should be segre-
gated and sent to the salvage dump.
■ 17. Property Responsibility. — a. Responsibility of the
shop officer. — All shop property, of whatever nature, is charged
to the responsibility of the shop officer or the commander of
11
17
ORDNANCE FIELD MANUAL
the parent echelon. It is the duty of the shop officer and of
all subordinate personnel at all times to safeguard such prop-
erty against loss or destruction.
b. Suballotment Of responsibility. — Since it is impracticable
for one person to exercise immediate supervision over property
that is as widely distributed as is the property of an ordnance
field shop, this responsibility is suballotted to the section fore-
men and the persons actually using the tools and equipment.
c. Responsibility of section foremen and workmen. — Sec-
tion foremen will sign for and be responsible for all special
tools and equipment assigned to the section and not signed
for by the workmen of the section. The workmen of a sec-
tion will sign and be responsible for kits of tools or equipment
assigned specifically to them and necessary in their work.
d. Scope of individual's responsibility. — This responsibility
extends to payment (in the zone of the interior) by the
individual, for such tools and equipment as he may not be able
to produce when he is separated from the organization or
shop assignment or goes on leave.
e. Provision for safeguarding assigned property. — Each per-
son signed for property should be provided with a means for
securing such property. No one shall without the knowl-
edge and consent of the person responsible for the property
take or borrow such property or break into or enter the con-
tainer or place where this property is stored.
/. Reports of property theft. — An immediate report Should
be made to the shop officer whenever there exists evidence of
such breaking and entering.
g. Responsibility for property lost or stolen. — In time of
peace or in the zone of the interior, property lost or stolen,
whether in garrison or in the field, must be replaced or paid
for by the individual responsible for the same, or the loss
may be made the subject of a report of survey. The decision
of the surveying officer that the property was lost through
the fault and neglect of the person concerned, will result in
the responsible soldier being compelled to pay for the property
in question.
h. Memorandum receipts. — Each soldier signing for prop-
erty will receive a duplicate copy of the debit memorandum
receipt, which he will keep for use in checking his property
12
ORDNANCE FIELD MAINTENANCE
17-19
so that he may know what he has signed for. Whenever he
turns in any item of equipment he will be given a credit
memorandum receipt signed by the shop officer. This he will
keep with the debit memorandum receipt.
i. Inventories. — Several times each year a complete check
of all property will be made by the responsible or account-
able officer or his authorized representative. A new consoli-
dated memorandum receipt will be issued to all persons
holding property.
j. Action on departure of soldiers. — When a soldier who has
signed for property leaves his station or organization for a
period in excess of 10 days, he should be required to check
all tools and equipment in to the chief of the stock section.
If the property is not all turned in, the balance not turned
in will be placed on a statement of charges. The shop officer
will be promptly notified in all such cases.
■ 18. Locks and Keys. — a. Custody of keys. — All keys except
those specifically assigned to individuals will be kept in a key
box in the shop office Cone copy of each). Extra keys should
be in the custody of the shop officer and may be kept in the
shop safe. All keys borrowed from the key box will be signed
for on a list provided, and returned as soon as the need for
them has passed. All persons charged with the security of
trucks or storage cabinets will assure themselves that such
places are secure before leaving them.
b. Duplicate keys. — When a key Is lost the lock hasp will
not be sawed. The matter will be called to the attention of
the shop officer who will provide a duplicate key. Persons
sawing locks will pay for them unless such sawing is author-
ized by the shop officer.
■ 19. General Shop Policies and Procedure. — a. Proper
channels for business transactions. — All persons having busi-
ness to transact will go first to the shop office. Shop per-
sonnel will not deal directly with such persons but will direct
them through the proper channels. If it is necessary for
persons requesting work to consult with a section foreman
they will be directed by office personnel directly to the section
concerned.
b. Loitering in shop. — Persons not having business in the
shop should not be allowed to loiter therein. Whenever it
13
19
ORDNANCE FIELD MANUAL
is required that a soldier stay in the shop with a car or
weapon, he will be allowed to do so. He should be required to
assist shop personnel.
c. Tagging unserviceable materiel. — Whenever materiel is
red tagged (OFM 201) and marked unserviceable as a result
of inspection, the tag should show under "Defects" the specific
reasons why the article has been marked unserviceable. In
addition the tag will carry the usual information, including
the proper nomenclature, the dates, and signature of the man
making the inspection. (See pars. 21 and 130.)
d. Records in gun and motor books. — Whenever ordnance
vehicles or artillery are brought to the shop for repairs, modi-
fications, or inspections, the proper motor or gun books should
be brought with them. All work of a major nature, such as
overhaul, replacement or repair of large and important com-
ponents, painting, or application of field service modification
work orders, will be entered in the book, together with the
dates, place of work, and signature of person making the
entry. (See pars. 24 and 25? and k.)
e. Authority for all shop work. — No work other than ord-
nance maintenance will be performed by the shop without
the specific authority of the shop officer in each case. (See
pars. 77 and 82.)
f. Certificates of fair wear and tear. — In time of peace or
in the zone of the interior, except during maneuvers, a cer-
tificate of fair wear and tear will be requested whenever it
seems doubtful that an item was rendered unserviceable
through fair wear and tear. In cases of materiel damaged
through accident, no work will be commenced until specific
orders to repair have been given by the shop officer. (See
pars. 20, 83, and 84.)
g. Receipts for weapons received from troops. — In time of
peace or in the zone of the interior, receipts should not be
given for weapons received from the troops until inspection
has shown that all principal and expensive components are

c. Work order. — The work order is then prepared by the
shop clerk in accordance with instructions of the shop fore-
man (see par. 62a-c incl. and pars. 77-90, incl.) . All sections
to work on the job should be indicated, all intershop work
orders prepared (see par. 101) and the job given a priority
rating. Usually only one section is concerned.
d. Doing the work. — The job and the work order then go
to the section where the work is to be done. The section
17
31-33

mark each Item issued on the bill of material and place it on
the proper hook file (see par. 98c) to await posting to the
bin cards at the earliest opportunity. If any items on the
bill of material for a current work order are not in stock,
prompt action will be taken to post the items Issued to the
stock card and place the incompleted bill of material in the
hands of the noncommissioned officer in charge of the sec-
tion for his action. (See pars. 86c, 91, and 98.)
b. Action when material is out of stock on a particular
truck. — Whenever material requested on a bill of material is
not in stock on a particular truck, the'stock man will promptly
call the matter to the attention of the chief of the stock
section for his action. The chief of the stock section will

the stock of the company is exhausted. If it is not, the
stock man will secure the materials from another stock truck.
The second stock man will post the issue to his bin card.
c. Action when material is low cm a particular truck. —
Whenever the total on a bin card approaches the minimum
amount of stock shown on the card, It Is the duty of the
stock man to prepare a brief memorandum for the chief of
the stock section informing him of the quantity of such items
needed for the replenishment of stock in the vehicles con-
cerned. This maybe done on a want list (OFM 110). (See

found on the retained copy of the requisition or on the want
list attached to the requisition. Care must be exercised that
property delivered to a shop section is received by a respon-
sible person who will know what to do with it. Items for
current work orders, if not immediately acceptable by the
sections, will not be binned but will be properly tagged with
a distinctive tag showing the work order number and section
to which it pertains and placed in a suitable place where
it may be seen. Every effort will be made to keep such prop-
erty moving. (See par. 10.)

DUTIES OP INDIVIDUALS
54. General. — In this chapter will be discussed the duties
ofNspeciflc individuals and classes of individuals in the field
shop.
■ 55. Continuity of Operation. — All personnel, officer or
enlisted, should endeavor to insure continuity of policy arid
work, by keeping the next person in the chain of command
or supervision informed of the current status of work or
of any changes of policy affecting the echelon in question.
An excellent method of crystallizing procedures, and of in-
suring such continuity of policy, is by the use of a "policy
book." All supervisory personnel should familiarize them-
selves with the capabilities and limitations of the personnel
under their supervision. Substitutes should be trained for
each job In the shoP, and men rotated from time to time
to insure continuity of operation in the event that losses
are experienced.
■ 56. Policy Book. — a. Description. — A policy book is a note-
book, or folder, in which is recorded for the future reference
of Interested personnel —
(1) The policies of the officer in charge of the echelon to
which the boob pertains, on problems the solutions of which
are discretionary with such officers.
(3) The procedures adopted for handling matters not
otherwise covered by authorized publications.
i>. Uses. — Such a book is most useful In maintaining a con-
tinuity of policy in operation, on changes of command, during
the absences of officers, and for the training of personnel In
the desires of the officer in charge. Sections of the book
should be properly titled and entries should all contain the
reference which is the authority for the entry, for instance,
"Co. order No. __ date," or "Shop Order No. _. date," or
"VOCO date," etc. As the book develops it should be prop-
454370°— 12 2 27
56-58
ORDNANCE FIELD MANUAL
erly indexed. If properly kept, the policy boob will develop
into a valuable source of information for the Office of the
Chief of Ordnance concerning the operations of type organi-
zations or sections.
■ 57. Shop Officer. — a. Responsibility and functions. — The
shop officer is responsible to the commander of the parent
echelon for the operation of the shop. He will exercise im-
mediate supervision over the shop office, through the shop
foreman. He must be thoroughly familiar with the opera-
tions and status of current work of all sections of the shop.
b. Planning for future requirements. — He will prepare the
necessary plans for future requirements of the shop, for
trained personnel, equipment and materiel (see par. 3).
c. Inspections. — He will make such scheduled and unsched-
uled inspections as may be necessary to insure the readiness
of all sections to function efficiently.

perform the work. (In general this designation is obvious
except where a question arises as to whether or not the service
section could best perform the work.)
£f. Final form and completeness of all inspection reports
(see pars. 127-137, incl.).
h. Completeness of all shop files (see pars. 105-112, incl.) .

any measures, in furtherance of the general policies of the
shop officer, deemed necessary to insure that deterioration of
equipment is not due to negligence or misuse. All cases of
negligence or misuse will be reported to the shop officer for
his action.
b. The officers in charge of shop sections should be expert
inspectors and know the best methods for repair of items
for which their sections are responsible. This expertness
must be obtained by actually performing some inspection and
repair work, by close observation of the performance of spe-
cialists in the section, and contact with the troops using the
materiel. It is not intended these officers will work as me-
chanics all or most of the time, for if this is done they will
neglect their supervisory duties.

Section I
BASIC PROPERTY RECORDS IN SHOP
■ 67. Property Records. — There should be maintained in the
shop, records or accounts covering parts and materials used
in the maintenance and supply of ordnance materiel to the
troops. The principles outlined in paragraph 97, regarding
modifications, are entirely applicable to the records listed
herein.
a. The stock record account may be maintained by a parent
echelon or the shop office. This account includes all items
of whatever nature shipped to or from the parent echelon or
shop on a proper shipping ticket.
b. The shop expenditure record is kept by the shop office.
This record includes all parts and materials used in the opera-
tion of the shop in the maintenance of ordnance materiel.
This record is the most important single record in the shop
for operations, and must be maintained even in the combat
zone.
c. The bin cards are kept by each section of the shop having
a spare parts truck. These bin cards include every item
carried by such trucks.
■ 68. Receipt of Materials. — a. 'When stock record account
is maintained by higher or parent echelon. — When the stock
record account for the parts and materials expended in shop
operation is maintained by a higher or parent echelon,
the following procedures will govern in the cases cited below:
35
68-70
ORDNANCE FIELD MANUAL
(1) Receipts of materials for use by both parent echelon
and shop. — The records cited in paragraph 67 will operate
in the following manner: AH shipments received by the parent
echelon on a shipping ticket will be picked up on the stock
record account. All parts and materials intended for expen-
diture in the operation of the shop will also be picKed up by
the shop office in the shop expenditure record, by shipping
ticket number, in the same manner as is prescribed for entries
in a stock record account. Such items will, when placed in
storage in stock trucks, be entered on the proper bin card.
The receipt of the chief of the stock section for such items
may be given by proper entries on the face of the duplicate of
the shipping ticket for' the items, or the matter may be
handled by the preparation of a memorandum receipt for the
material for the signature of the shop officer. In general,
the latter method will not be necessary.
(2) Receipt of materials for shop only. — Whenever ship-
ments of materials are received which are intended exclu-
sively for expenditure in the shop, the shipment may be sent
directly to the chief of the stock section, who will check the
materia] and initial the duplicate in the same manner as is
customarily done by the office of the parent echelon for other
shipments. The chief of the stock section will then pick up
the material on the shop expenditures record, and the proper
bin cards, and send the shipping ticket with the duplicate
to the parent echelon.
b. When both stock record account and expenditure record
are maintained in shop office. — In this case necessary modi-
fications of the above-cited procedures must be made.
■ 69, Expended Materials. — Material expended on work or-
ders will be entered in the shop expenditure record in the
manner outlined in paragraphs 72 and 89.
■ 70. Dropping Stocks prom Stock Record. — Whenever con-
solidations of parts and materials used (see pars. 74 and 99)
are prepared for higher authority, sufficient additional copies
for the finance officer should be prepared. These copies,
when supported by the proper certificate of expenditure and
approved by proper authority, constitute the authority or
voucher for dropping the material from the stock record
account. (This procedure will usually be necessary only in
time of peace or in the zone of the interior.)
36
ORDNANCE FIELD MAINTENANCE
71-73
■ 71. Shop Expenditure Record <OFM 105) . — The shop ex-
penditure record consists of one stock record card (QMC
Form No. 424; see fig. 2) for each item of parts or kind of
materials used. The caTds will be arranged in the expendi-
ture record book by groups and will be arranged among them-
selves In the same manner in which they appear In the
Standard Nomenclature list for that particular group. This
record constitutes the master record for all parts and mate-
rials that are carried by the shop for use in the maintenance
of ordnance materiel.
■ 72. Entries in Expenditure Record. — The data for the
expenditure record are secured from shipping tickets and
from the work orders of the shop and are posted to the record
by the shop clerk who records receipts by date, shipping ticket
number, quantity, and balance, and expenditures by date,
work order number, the quantity Issued, and balance. When-
ever the clerk posts any voucher to the expenditure record
he should place on the face of the voucher a notation to the
effect "posted to E. R." with his initials and the date.
■ 73. Stock Levels. — a. Maximum and minimum figures. —
Each record pertaining to an item will have marked on it in
the proper place the maximum and the minimum amount of
the material considered necessary to have on hand. These
maximum and minimum figures should not be considered as
fixed beyond all change once they have been determined. The
personnel of the shop office and the stock section should be
constantly alert to note any necessity for change of these
figures and to make recommendation to the shop officer when
changes aTe considered necessary.
b. Basis of maximum and minimum stock levels. — The de-
cision covering the maximum and minimum quantities of
any item of stock to be carried by the shop should be arrived
at only after a consideration of the following factors:
(1) Total number of major items in which the replacement
item is used, in units supported by the shop.
(2) Percentage of failures which may be expected within
a stated period. The period chosen may be one month or
one week or any other period either prescribed or considered
necessary (see par. 3) .
(3) The weight or size of the item. (This is involved with
the tonnage and space available to store the materiel.)

(4) The expense of the item and the difficulties of procure-
ment. Some of the factors listed above may be evaluated
accurately. Others can only be an estimate. Continuous
planning is necessary to insure a completely satisfactory
solution to the problem.
■ 74. Basis for Consolidation op Parts Used (OFM 102)
(see par. 99). — The shop expenditure record not only con-
stitutes the record of the total items in storage in the shop,
but also is used for the consolidation of parts used in the
maintenance operations of the shop (see par. 99). In order
to use this form properly for the preparation of the con-
solidation, two steps are necessary. In the first step the clerks
must go through the entire expenditure record, draw a line
under the last entry and add up the items issued during
the period in question. This figure should then be placed
in the space under the line drawn across the sheet and a
notation of the date and consolidation number placed in the
proper place. When this operation has been completed for
the entire expenditure record, the clerk should then list the
items directly from the expenditure record to the consolida-
tion form. Thus, the items expended will appear on the
consolidation form in the proper order by groups, and no
items will be listed on the consolidation that have not actually
been expended during the period.
■ 75. Replenishment of Stocks. — Whenever stocks within
the shop approach the minimum figure listed on the expendi-
ture record, steps should be taken to replenish such items
at the earliest opportunity. In garrison it may be desirable
to clip a red strip of paper or other marker to the sheet
and to consolidate all such requirements at some later date.
Or, it may be desirable to prepare an abstract containing
the required data for inclusion in a requisition when the
number of items becomes sufficient to warrant the prepara-
tion of one. In the field, however, where the shop may not
remain in the same place long enough to await supply, it
is best to place daily requisitions for requirements (see pars.
91-96, incl.).
■ 76. Bin Cards (see fig. 3, OFM 104) . — a. Function. — Bin
cards are designed to maintain a running record at the point
of storage of all items in storage. OFM 104 should be used
39
76
ORDNANCE FIELD MANUAL
a*
for this purpose. Each form bears sufficient data on its face
to enable its use also as a location card. One card is main-
tained for each item in stock.
6. Description. — OFM. 104 is a visible record form. It is
furnished in two colors, light green and orange. The light
40
ORDNANCE FIELD MAINTENANCE
76-79
green card is furnished in quantity. A lesser number of
orange cards are furnished since it is intended that they
will be used principally as indicators of changes in alphabet.
It is kept in a visible index metallic folder. Each folder has
a capacity of 106 cards, and there are 10 folders in the
metallic cabinet provided for each spare parts truck.
c. Operation. — Whenever an issue is made, or as soon
thereafter as is convenient, the stockman posts to the card
the quantities of materials issued. He must be constantly
alert to the quantities remaining in stock. Whenever such
quantities fa]] near the minimum prescribed on the card,
he should notify the noncommissioned officer in charge that
such is the case, in order that a proper request for addi-
tional stocks may be made before stocks are depleted. The
use of the special markers or flags provided will assist in
reminding of these needs.
Section n
WORK ORDER COFM 103)
■ 77. General. — In the system of shop operation outlined in
this manual, the Work Order (OFM 103), figures 4 and 5, is
the basic shop record for all work done, and for all issues
of material made to the troops by the shop. Work orders
are issued by the shop office as the authority for the accom-
plishment of work or the issue of supplies. Except as de-
scribed in paragraph 82, no work should be performed or
issues made without an approved work order. Unless other-
wise directed by the shop officer, the authority to issue work
orders rests with the shop officer and the shop foreman.
■ 78. Recording Wobk Orders. — A record of each w rk or-
der issued is kept in the work order register (see par. 100).
■ 79. Numbering Work Orders. — a. Normal. — Work orders
issued for each regiment or separate unit should be num-
bered serially for that unit. Each series should begin with
"one" on July 1st of each year. In order to identify the
work order by unit and material, the work order number con-
sists of three parts. A typical work order number w uld be
"l^G-33." In this number group the first number is the
code symbol which identifies the unit for which the work order
was issued. The letter "G" indicates the group in which the
41
79-82
ORDNANCE FIELD MANUAL
material is listed (see Ordnance Publications for Supply Index
(OPSI) for lists of materials by groups). The number "33"
indicates that this was the 33d work order issued to that or-
ganization in the fiscal year. (For work orders covering
FSMWO, see par. 89c.)
b. Numbering for maneuvers in time of peace. — It is some-
times desirable to establish a separate series of work orders
for maneuvers in order to readily separate garrison work or-
ders from field work orders, In this case, the work order
numbers will be started from number one, and the suffix "M"
may be placed after the last number of each group. For
instance, the number cited in a above would thus become
"1-G-33M.*'
c. Numbering for units with which shop does not normally
have contacts. — In this case work orders may be assigned an
identification symbol or number in the first position which
indicates that the work order is for a miscellaneous unit. The
name of the unit should be written after the number group.
An example of such a number would be "X-D-40M-77. F. A."
This indicates that this is the 40th work order issued to mis-
cellaneous units during the maneuvers, that the work was
done on artillery materiel, and that the unit served was the
77th Field Artillery.
■ 80. Issuance of Woek Orders in Theater of Operations. —
In the combat zone, and during peacetime maneuvers when
directed by proper authority, work orders will be issued on
any form of request, written or oral, made by the organiza-
tion requiring the performance of work or the issuance of
supplies.
■ 81. Issuance of Work Orders in Zone of Interior or in
Time of Peace. — In the zone of the interior or during peace-
time, work orders are usually issued on the written request of
the commanding officer of the organization desiring the work
to be done. This request should state the nature of the re-
pairs required and the cause of damage and should bear a
certificate of fair wear and tear (see pars. 83 and 19/) cover-
ing the damage,
■ 82. Performance of Work Without Work Order. — Cir-
cumstances wherein work m&y be performed or supplies issued
without an approved work order are as follows :
a. On the march, when emergency repairs are required.

44
ORDNANCE FIELD MAINTENANCE
82-85
d. In all such cases, sufficient notes should be made by the
shop personnel to form the basis for a work order, and when
opportunity presents itself, a work order will be prepared.
■ S3. Certificate of Fair Wear and Tear. — The following Is
a typical certificate of fair wear and tear. "I, the under-
signed, certify that the loss or damage to the items listed on
this request was due to fair wear and tear in the military
service and not due to the fault or neglect of anyone."
■ 84. Action on Materiel Not Covered by Certificate of
Fair Wear and Tear. — In time of peace or in the zone of the
interior, except during maneuvers, whenever materiel is re-
ceived at the shop for repair that appears to have been dam-
aged by causes other than fair wear and tear, a certificate
will be requested. If none is furnished, the matter will be
called to the attention of the shop officer. The shop officer or
his immediate superior should, through the proper channels,
request of the proper headquarters, the appointment of a
board of officers to determine the responsibility in the case.
No work order should be issued until the board has signified
that the repair or replacement may be accomplished. This
will usually be as soon as the members of the board have seen
the item in question.
■ 85. Procedure Governing Issue of Work Orders by
Shop Office. — o. Requests to shop office. — The materiel upon
which the work is to be done is presented with the proper
request at the shop office. If the question Is one of making
an issue of supplies, the request is presented to the shop office.
If it is one of making an issue of replacement items, the un-
serviceable items should, in time of peace or in the zone of the
interior be presented at the shop office.
b. Inspection of materiel by shop foreman. — The materiel
is inspected by the shop foreman or his representative, for a
determination of the action to be taken in the case.
c. Preparing work order. — When directed by the shop fore-
man, or his representative, the work order is prepared in
proper form and is given a number secured from the work
order register.
d. Number of copies. — Each work order should be prepared
in duplicate and distributed as follows:
45
85-88
ORDNANCE FIELD MANUAL
(1) Original with certificate of organization commander
attached, together with the materiel or equipment, to the
section concerned.
(2) The tally-in section of the original work order is com-
pleted by the chief of section and given to the representative
of the organiaation to which the materiel belongs, as a receipt
for the materiel.
(3) The duplicate copy of the work order with a copy of
the certificate of the organization commander attached, is
placed in the shop office file of work orders (current).
(4) The tally-in section of the duplicate copy is completed
and sent to the parent echelon as a notice that the materiel
is in the shop undergoing repairs.
■ 86. Wokk Orders on Serially Numbered Items. — Every
work order covering serially numbered materiel will show the
serial numbers of such items or if the number of such items
is large will bear a specific reference to the shop record (i. e.,
the work order request of the organization commander),
where these numbers may be found.
■ 87. Action by Workman in Shop. — The workman in the
shop will perform the needed repairs or replacements of parts.
He should make notations on the face of the work order of
the repairs actually performed. He should enter on the re-
verse of the work order the quantities and kinds of parts and
materials used in accomplishing the work.
■I 88. Action by Section Foreman. — When the required work
is completed the section foreman will check the work orders
for completeness, and will assure himself that all pertinent
entries such as materials used, actual work performed, type
of failure involved, time job was completed, etc., are entered
on the work order. He should inspect the job, and assure
himself that it is entirely satisfactory. If the job is an im-
portant one he should notify the shop foreman or the shop
officer. When all necessary steps have been taken to insure
that the job is satisfactory, the organization to which the
equipment belongs should be notified. When the work is
released to the using organization the tally-out portion of
the form is dated and signed by the representative of the
using organization. The work order is then sent to the shop
office.
46
ORDNANCE FIELD MAINTENANCE
89
■ 89. Action by Shop Office on Completed Work Orders. — a.
Action by shop officer and shop foreman. — The shop officer
and the shop foreman should scrutinize the finished work
orders for any details concerning the time the job was in the
shop, the organization to which it pertained and other details
which may be of interest. Whenever the shop foreman or
shop officer checks a work order, he should place his initials
on its face in one corner.
b. Entries in gun and motor books. — Whenever it is required
that entries be made in gun or motor books, this matter may
be handled in either of two ways. The various units may
be required to bring the hooks to the shop with the materiel,
and the entries may be made by the shop office personnel
from the completed work order, or the necessary extracts
may be made from the completed work order and sent to the
organization for entry in the proper book. It will be found in
practice that the former method is the better if the gun and
motor books are to be of any value for future reference.
c. Entries in record of status of field service modification
work orders. — All work orders should be carefully scrutinized
to note whether or not the work performed was required by
an PSMWO. All such work should be recorded on the proper
sheet of the status record (see par. 102) . The PSMWO num-
ber may be placed on the work order with the work order
number.
d. Action by shop clerk. — The shop clerk should check with
the chief of the stock section to insure that he has all the bills
of material (OFM 101) pertaining to a given work order and
should then check the bills of material against the proper
work order. Any discrepancies on the work order should be
corrected. The parts and materials listed on the reverse of
the work order should be posted to the expenditure record.
When practicable the shop time and parts and materials cost
are posted to the work order register. When such postings are
made, the shop clerk should make a notation in the left center
or other suitable part of the work order, "posted to E/R and
W. O. R." followed by his initials. The original work order
together with all pertinent papers such as additional sheets
and the certificate of the organization commander are filed
in the proper file (see par. 106) , The duplicate work order

is removed from the file of work orders (current), is then
completed, and sent to the parent echelon if required.
■ 90. Issues or Materials. — Whenever ordnance general sup-
plies are issued to the using troops by the shop, the work
order (OFM 103) should be used to record the transaction.
The form should be filled out in the usual manner except
that it will bear in the line "Work to be done," the words
"Issue of supplies," and the letter in the identification num-
ber group will be "I." The supplies to be issued will be listed
on the reverse of the form. In this case the duplicate of the
form will be sent to the parent echelon as soon as the trans-
action is completed. This work order is then posted to the
expenditure record in the usual manner (see par. 72) , and filed
in the general file of work orders (completed) (see par. 106),
pertaining to the organization to which the issue was made.
Section ITJ
PROCEDURE GOVERNING REQUISITIONS
■ 91. Priority op Requisitions. — The preparation and dis-
patch of requisitions should as far as practicable take prece-
dence over all other shop office activities. This is necessary
in order to cut to a minimum the "dead time" lost between,
the receipt of a "want list" in the shop office and the receipt
of the material required.
■ 92. Preparation of Requisitions. — Upon receipt of one or
more want lists, the chief of the stock section will examine
them for correctness, completeness, and suitability in meeting
shop requirements. He will secure the approval of the shop
foreman, who should initial each approved want list. The
chief of the stock section should then prepare the neces-
sary requisition on QMC Form No. 400, and assign to it the
proper requisition number.
■ 93. Notes Placed on Requisitions. — Whenever want lists
bear descriptive remarks relating to the type of materiel for
which the items requested are required, these remarks should
also be placed in note form on the face of the requisition for
such items. Whenever the want list shows work order num-
ber for which particular materials are required, the work
order numbers should also be placed below the items on the
48
ORDNANCE FIELD MAINTENANCE
93-98
requisition. These notes are necessary to assist the supply
agency and the battalion supply officer to supply the proper
Items and to know which items are necessary for immediate
use and which may be delayed for a short time if necessary.
■ 94. Action by Shop Officer. — The requisition, when pre-
pared, wiil be given to the shop foreman for checking and
the placing of his Initials on the second copy. It will then
be turned over to the shop officer for his signature. The shop
officer should be promptly notified whenever a requisition is
awaiting his signature.
■ 95. Piling Retained Copy. — As soon as the requisition is
signed by the shop officer, the second copy of the requisition
together with the original copy of the want lists, which should
be attached thereto, should be filed in the file of requisitions
(unfilled) (see par. 107).
■ 96. Transmittal of Original. — The three remaining copies
should be sent by messenger to the proper office for supply
or other action. Requisitions must be delivered to responsible
individuals at the higher echelon of supply, and should be
given immediate attention as soon as received at such points.
Section IV
FORMS AND THEIR USE
■ 97. General. — The forms for use in shop operation de-
scribed herein and elsewhere in this manual have been de-
signed and coordinated one with the other, to provide a
simple, complete, and efficient operating procedure for an
ordnance shop operated by enlisted personnel in time of war.
They are all designed to support the shop expenditure record.
If the requirements of coordinated planning and continued
efficient operation are to be met, practically all of the forms
must be properly used. Modifications of the system may be
made, both by addition and subtraction. Before such modifi-
cations are made, however, the responsible individual should
carefully consider their effect upon the accuracy of the shop
expenditure record.
■ 98. Bill of Materials (OFM 101, fig. 6). — a. Descrip-
tion. — This is the form used by a workman for drawing
materials from the stock truck for use on a work order.
49
98
ORDNANCE FIELD MANUAL
b. Use. — The form should be completely and accurately
filled out giving the exact nomenclature and part number
as listed in the Standard Nomenclature Lists. When ap-
proved by the section foreman, it should be presented at the
stock truck where it Will be filled if the material is on hand.
All items drawn on a bill of materials should also be listed
on the back of the work order by the workman.
c. Procedure "by stockman. — The stockman should issue the
materials carried on the stock trucks only on a bill of mate-
rials. When the issue has been completed, a check mark or

other notation indicating that the issue has been made should
be placed on the form. As soon as is convenient without
holding up other issues, the stockman should enter the issue
on the bin cards. For use in cases where posting cannot be
made immediately, there should be available on a board in
the truck, two hooks for riling the forms. One should be
marked "Unposted" and the other should be marked "Posted."
Until posted to the bin cards, the bills of materials should be
held on the unposted file; after posting they should be trans-
ferred to the posted file. Periodically the stockman should
return all posted Forms 101 to the shop office for checking
against the finished work orders.
50
ORDNANCE FIELD MAINTENANCE
98-101
d. Action when material is not on hand. — Whenever bills
of materials are presented for stock which is not on hand,
the matter should, be promptly called to the attention of the
chief of the stock section for his action.
e. Procedure by shop clerk. — For the procedure of the shop
clerk governing the handling of these forms, see paragraphs
72 and 89d.
f. Filing forms. — After these forms have been checked
against the work orders, they have no further use except
for possible future reference. They may be sent to the office
of the parent echelon.
■ 99. Consolidation op Parts Used (OPM 102, fig. 7). — This
form is prepared by the shop office periodically as required
by higher headquarters. The source of the data for this form
is the Expenditure Record (OFM 105). In general it will be
prepared in triplicate, two copies being sent to 1 higher head-
quarters. One copy is retained on file in the shop office. A
copy of this report, supported by an approved certificate of
expenditure will serve as a voucher to the stock record ac-
count for dropping the material (see pars. 70 and 74).
■ 100. Work Order Register (OFM 106, fig. 8). — This is a
record of all work orders issued. Separate sheets are main-
tained for each regiment and separate organization. Work
orders are numbered consecutively for each unit, beginning
with number one on July first of each year. The record shows
the date the order was issued, the work order number, the
items covered by the work order, and a consolidation of the
shop time and parts and materials cost for each work order.
There should be inserted in some convenient place within the
binder, a code or legend index to the identification numbers
assigned the various units served, and the list of letters used
to identify materiel by groups. (See par. 79 and OPSI.)
■ 101. Intershop Order (OFM 107, fig. 9). — a. Description. —
This is a suborder to a regular work order (OFM 103). It is
made out by the section foreman to secure work under a
regular work order. The work required by the OFM 107
is usually to be accomplished by the service section on the
material sent from one of the other sections, but it may be
made out on any other section if required.
b. Use. — The intershop work order will bear the number
51
101-103
ORDNANCE FIELD MANUAL
of the regular work order, the date, a description of the work
required, and the signature of the section foreman requesting
the work. It Is prepared in duplicate. One copy goes to the
shop office, the other to the section requested to do the work.
The shop office copy should be placed In the file of work
orders (current) with the work orders to which It pertains.
When the work is finished, the OFM 107 will be dated and
signed by the workman doing the work. This copy will be
returned with the job to the foreman of the initiating sec-
tion. It will then be attached to the original work order and
returned with the work order to the shop office when the
original is returned.
■ 102. Status of Field Service Modification Work Orders
(OFM 108, figs. 10 and 11) . — This form is designed to provide
a complete record of the status at any time of any field service
modification work order, (FSMWO) being performed by the
shop. This matter is one which requires constant attention
on the part of all office personnel, because in the daily routine
of shop operation it frequently happens that postings to this
record are not properly made. This record constitutes the
basis for the periodic report on this subject, required by
higher headquarters. The instructions on the reverse of
the form contain complete details covering the use of the
form.
■ 103. Consolidation of unfilled Requisitions (OFM 109,
fig. 12) . — a. Description. — Delays will often be experienced in
receiving supplies on requisitions. In time, numerous requi-
sitions will be added to the unfilled requisition file. In order
to simplify the problem of checking these requisitions it will
sometimes be advisable to establish a Consolidation of Un-
filled Requisitions (OFM 109). This form Is designed to
provide a quick check on the status of unfilled requisitions
and to furnish the basis for action in cases of items unduly
delayed. When the items listed on unfilled requisitions have
been transferred to the consolidation form, these requisitions
may then be placed in the filled requisition file. When such
items are posted from the requisition to the consolidation
a notation should be made on the requisition that such post-
ing to the consolidation has been made, and the entry on the
consolidation should bear the number of the requisition from
which the entry came.

t>. Action on receipt of property. — When items are received
as a result of the requisition, the date of receipt may then
be posted to the consolidation. As items listed on the con-
solidation are checked off as having been received, it may
from time to time be necessary to make a new consolidation.
This will include the remaining items on the old consolida-
tion plus such additional items as may be on other unfilled
requisitions which have been submitted since the first con-

face the date on which it was made.
c. Handling large lists of property. — In cases where the
inclusion of an unfilled requisition of several pages is re-
quired on the consolidation it will sometimes be better to
cite the number of the requisition in the proper place and
to retain the unfilled requisition in the unfilled file, until,
it is filled or reduced to a size that is more easily included
in the current consolidation.

d. Other uses. — There will be circumstances under which"
It will not be practicable or desirable to use section want
lists, however, in general such lists will be of considerable
assistance in maintaining the proper stockage of material
and the required number of tools, etc. This form may also
be used by the stock man from time to time for the listing
of items needed for stockage of spare parts trucks.
Section V
SHOP FILES
■ 105. Work Orders (Current) . — a. Function. — Duplicates
of all work orders issued, except those for issues of supplies,
are filed for all organizations In a single file. This file pro-
vides the check required by the shop officer as to what work
is in the shop. The shop officer should be familiar with
the contents of the file and when a job appears to be unduly
delayed, should take proper steps to determine and correct
the cause of the delay.
b. Securing work orders in file. — All work orders should be
securely fastened into the file to avoid possible loss.
C- Removing work orders from file. — When a job is com-
pleted, the duplicate work order is removed from the file as
described in paragraph 89d, and sent to the parent echelon.
■ 106. Work Orders (Completed). — a. Three categories. — In
order to make readily available for reference any work order
in the shop office files, the following system of files of com-
pleted work orders should be maintained in manila folders:
(1) A separate file for each type of ordnance vehicle.
(2) A separate file for each type of artillery piece.
(3) A separate file for each regiment and separate organ-
ization, for all work orders not included by (1) and (2) above.
b. Register of serial numbers of related items. — This regis-
ter will contain serial number lists of the artillery weapons of
60
ORDNANCE FIELD MAINTENANCE
106-112
each organization served by the shop, together with serial
number lists of all items such as recoil mechanisms, carriages,
fuze cutters, etc., that pertain to each weapon. This register
is useful in identifying serial numbered items which have
become separated from related materiel while in the shop.
■ 107. Requisitions (Unfilled). — The retained copy of each
new requisition goes into this file as soon as it is completed.
It stays there until it is completely filled, or until the re-
maining items on It have been transferred to a consolidation
of unfilled requisitions. When any item carried on a requisi-
tion is received, an entry that it has been received together
with the date of receipt and the initials of the person, making
the entry, should be made on the requisition.
■ 108. Requisitions (Filled). — Each completely filled requi-
sition and each requisition from which the remaining items
have been transferred to a consolidation of unfilled requisi-
tions, is filed in this file. When a requisition is ready to file
here, the notation "Pilled" should be made across the bottom
of each sheet. There may also be placed in this file all
consolidations of unfilled requisitions which have served their
purpose.
■ 109. Requisition Register. — This Is a simple record for
which no particular form is necessary. It should record the
serial number of all requisitions, the date of preparation, and
as a matter of information, the groups (SNL) of the materials
requested thereon. The record may be kept inside of one
of the requisition files, for easy reference.
■ 110. Consolidations of Parts Used. — These consolidations
constitute the record of the parts and materials used by the
shop during any given period. The retained copies are valu-
able for planning purposes.
■ 111. Inspection Reports. — Retained copies of inspection
reports should be filed in the file of the organization respon-
sible for the condition of the weapons or material. Within
this limitation they should also be filed by weapon or type
of material.
■ 112. Miscellaneous Piles. — a. Contents. — These will in-
clude correspondence pertaining primarily to the shop, Ord-
61
112
ORDNANCE FIELD MANUAL
nance Department publications, such as ordnance field
service circulars and bulletins, and various War Department
publications.
b. Use of Dewey Decimal System. — Whenever possible, it is
best to set up the filing system on the Dewey decimal system,
since this is the system in use throughout the Ordnance
Department and the Army.

CHAPTER 7
ORDNANCE INSPECTIONS
Section 1. Conduct of inspections
II. Inspection forms
Section I
CONDUCT OP INSPECTIONS
■ 113. Purpose. — The purpose of ordnance inspections may
be summarized as follows:
a. To determine the serviceability, completeness, and readi-
ness for field use of the ordnance materiel with which the
troops are equipped..
b. To discover the difficulties that the combat troops may
be experiencing with their materiel, and to increase their
combat efficiency by providing remedies for these difficulties.
■ 114. Types. — Ordnance inspections may be divided into two
general types:
a. Type A, which is represented by the formal inspection of
all ordnance materiel in the hands of a unit. In this category
would fall all annual inspections, and inspections of all ma-
teriel in the hands of the troops both before and after combat.
b, Type B, which is represented by the routine inspection
performed on ordnance materiel incident to its repair when-
ever it comes into the hands of ordnance maintenance per-
sonnel. In this category would fall inspections performed
incident to the repair of weapons brought into the shop by
the troops or repaired by contact or maintenance parties in
the field (see sec. n> .
■ 115. Authority , — a. All type A inspections must be au-
thorized through command channels. Ordnance inspection
parties will not inspect units of any command without previ-
ously reporting to all commanders concerned, displaying their
authority therefor, and asking the cooperation of the com-
manders concerned.
b. In time of peace, inspections are conducted in accordance
With the provisions of AR 45-30.
Paragraphs
113-126
127-137
63
115-118
ORDNANCE FIELD MANUAL
e. No special authority is required for type B inspections.
Such inspections are incidental to the repair of materiel, and
are a necessary step in the accomplishment of the repairs.
■ 116. Information. — The information for the Inspection of
ordnance materiel is contained in the Technical Manuals in
the series numbered from 9-1000 to 9-1999, inclusive, and in
the Standard Nomenclature Lists. The technical details are
fully covered in the Technical Manuals. The lists and allow-
ances of spare parts and equipment such as accessories, fire
control equipment, and articles for instructional purposes are
contained in the pertinent Standard Nomenclature Lists.
■ 117. Ordnance Officer Present at Inspections. — Whenever
practicable, an ordnance officer will be present at all inspec-
tions of ordnance materiel in the hands of troops.
* 118. RESPONSIBILITY OF ORDNANCE PERSONNEL. £5. Gen-
eral. — All ordnance personnel charged with the detailed in-
spection of ordnance materiel are responsible that all mate-
riel that oomes into their hands is thoroughly inspected and is
satisfactory for service when it is returned to the troops for
use.
b. Use of unserviceable materiel for training purposes. — If
circumstances occur in which the parts or materials necessary
to place the materiel in serviceable condition are not imme-
diately available and no serviceable replacement for the ma-
teriel is available for issue, it may be possible and necessary
to release the materiel to the troops for training purposes
only, with an agreement covering the use to which it Is to be
put. In such a case the limitations covering Its use must be.
thoroughly understood by the using personnel, and the signa-
ture of the responsible officer covering such an understanding
should be secured before the materiel is released.
c. Stand&rd of maintenance. — It Is one of the duties of ord-
nance personnel to set the standard of maintenance which
is expected of the troops, particularly with regard to the
cleanliness of weapons. It is not intended by the above that
ordnance personnel will be expected to perform all the clean-
ing operations necessary on ordnance materiel. It is, how-
ever, intended that materiel brought to the shop for repairs
will be reasonably clean, and that all metallic parts will be
free of rust, caked dirt, mud, or unauthorized paint. Wfcten-
64
ORDNANCE FIELD MAINTENANCE
118-121
ever practicable, the using arms may be required to clean the
materiel properly. Inspection parties should provide them-
selves with adequate cleaning facilities, and should insure that
materiel returned to the troops is properly cleaned and lu-
bricated. The application of this paragraph in the combat
zone will depend on the situation, and under such circum-
stances should be intelligently interpreted.
■ 119. TJse of Worn Parts as Replacements. — o. It will some-
times happen that a part which is worn so as to be unservice-
able in a certain item of materiel, will fit into and function
satisfactorily in another item of materiel. This is particularly
true In the case of small arms. The use of worn parts as
replacements Is uneconomical, in that it requires the expendi-
ture of the same amount of time and labor as does the installa-
tion of new parts, and provides no insurance against the early
failure of the item, perhaps at a critical time.
b. Worn parts should not be used for replacement purposes
in items of ordnance requiring repairs. New parts will be
used in all cases, and all old parts will be destroyed to pre-
vent their future use.
■ 120. Action Prior to Inspection. — Prior to sending an
Inspection party to a unit which it is planned to inspect, the
shop officer or his representative, should contact the unit
commander personally to determine a mutually satisfactory
time and place for the Inspection, and to request that the
inspection party be furnished with a complete list of all ord-
nance materiel in the unit. In general, this list need in-
clude only major items, with serial numbered items arranged
in proper numerical sequence. This list should be available to
the inspection party a day or two before the inspection is
scheduled.
■ 121. Organization of Inspection Parties. — a. Inspection
parties are organized in the manner best suited to the accom-
plishment of the assigned mission, and the personnel avail-
able. The most general case is the party assigned to make
a type A inspection of a unit. Such a party may, for pur-
poses of discussion, be divided into sections. These sec-
tions may be designated —
(1) Small arms section.
(2) Artillery section.
65
121-122
ORDNANCE FIELD MANUAL
(3) Automotive section.
(4) Instrument section.
(5) Miscellaneous items and accessories section.
b. Each section should include a recorder and a number
of inspectors and repairmen, as required to make a com-
plete inspection of all ordnance materiel in the organization.
It may not always be necessary to use all of these sections.
■ 122. Operation of Small Arms Section. — a. General. — The
operation of the small arms section inspection party is ma-
terially affected by the circumstances under which the in-
spection is conducted. The differences in method of oper-
ation are dictated by the types of records which are required
to be maintained, which in turn is governed by the ques-
tion of whether or not the inspection is being conducted in
the combat zone. The matter of inspection records will be
discussed in detail in section LT. The methods of opera-
tion outlined below are intended merely as a guide. They
outline general methods of procedure. A careful study of
the problem in the light of this manual and the require-
ments of a specific situation should yield a satisfactory solu-
tion to a special problem.
b. Four general methods of operation. — (1) Probably the
most efficient method of operation is that in which the inspec-
tion party is divided into two subsections, the inspectors and
the repairmen. Weapons are laid out according to serial
numbers. The inspectors pass along the weapons and make
a complete inspection of each one. The information con-
cerning each weapon is called off to the recorder by serial
numbers. An inspection ticket (see par. 131d), is prepared
for each weapon requiring repairs and secured to the weapon
by some Convenient means. Repairmen make the necessary
repairs and list the parts used on the inspection tickets,
which may later be collected and the parts used consolidated
in any manner required.
(2) In circumstances where there is neither the space nor
the facilities to conduct the inspection as indicated in (1)
above, the following system is suggested. Each man in the
party, except the recorder, functions as both inspector and
repairman. Each inspects a weapon, calls off the informa-
66
ORDNANCE FIELD MAINTENANCE
122-123
tion to the recorder and repairs the weapon, telling the
recorder what parts he uses in making the repairs.
(3) In circumstances where the inspecting party lacks the
tools or the spare parts to complete the necessary repairs,
the following method may be employed: Each piece in-
spected is tagged with an Inspection ticket properly com-
pleted, and the data are recorded on the proper record form.
The organization commander is requested to bring the
weapons to the shop, or a repair party is later sent to the
organization with the necessary equipment and parts to
finish the job.
(4) Under the most difficult operating conditions in the
field, it may happen that it will be totally impracticable and
undesirable to make any records of the inspection except
perhaps a record of the parts used on a recorded number of
weapons. In this case a list of the parts used may be obtained
by a difference in inventory when a suitable opportunity for a
check presents itself.
c. Procedure when complete inspection report is required. —
A complete inspection report includes a report on each weapon
by serial number showing defects found, repairs made by
ordnance personnel, those to be corrected by organization
personnel, and any other action required. Prior to the-
commencement of the inspection, all weapons in the organiza-
tion, to be inspected, should be listed in numerical sequence
on the appropriate forms (see par. 127). The necessary
records are obtained as outlined in b(l) or <2) above.
d. Procedure when abbreviated reports are satisfactory. —
When abbreviated reports are satisfactory, a study of the
type of report required and of the methods of inspection out-
lined in this paragraph, should yield a satisfactory solution
to the requirement.
■ 123. Operation of Artillery Section. — a. Special consid-
erations. — Because artillery materiel is not easily handled
or maneuvered, the procedure for this section varies some-
what from that of other sections.
b. Forms. — The recorder of the section should be equipped
with all the necessary detailed forms covering every point
which it Is necessary to check on the weapon and the equip-
ment pertaining to it, such as caissons, limbers, bogies, etc.
(see par. 132).
67
123-125
ORDNANCE FIELD MANUAL
c. Simultaneous inspections. — Whenever possible the in-
spection party should be so organized that the simultaneous
inspection of two or more items pertaining to the gun may
be carried out. A single recorder should suffice for the entire
inspection.
d. Shelter. — Whenever possible, the inspection of artillery
materiel should be conducted under shelter where protection
from rain and dust may be secured. In garrison this will
usually be in the shop building of the company conducting
the inspection, but it may be the gun sheds of the organiza-
tion being Inspected. In the field, it may be necessary fo
use existing civilian structures, or in some cases, to erect
storage tents or tarpaulins for this purpose.
■ 124. Operation of Automotive Section. — a. Time re-
quired. — As is the case in the inspection of artillery materiel,
the inspection and repair of ordnance vehicles requires more
time than is required on smaller items of ordnance.
b. Repair. — In general, in performing type A inspections,
it is best to repair automotive vehicles at the time of the
inspection. This reduces the number of times the vehicle
is required to be brought to the shop, thereby reducing the
"downtime," and eliminating the extra inspection which
would be required if the vehicle were released and subse-
quently returned for work.
c. Special considerations. — In some circumstances it may
be desirable to make a complete, rapid inspection of all vehi-
cles for the purpose of determining the quantities and types
of spare parts which will be required. This will be an excep-
tion, however, arid should not become standard practice.
(See par. 48b.)
■ 125. Operation of Instrument Section — a. Require-
ments. — This section should have a quiet space set aside
for its work, with sufficient field of view to enable the neces-
sary tests of optical elements to be made. The space pro-
vided should be dry and protected from dust.
b. Repairs. — In general, this section will complete necessary
repairs that are within its capabilities at the time of the
inspection.
c. Forms. — The recorder should have on hand the required
forms for the type of materiel that is to be inspected. All
63
ORDNANCE FIELD MAINTENANCE
125-126
instruments should be recorded by proper nomenclature and
serial number.
d. Repairs by higher echelon. — The inspection of optical
instruments is complicated by the fact that spot repairs are
frequently not possible because of the lack of skill, tools,
materials, or a proper place in which to work. Under such
circumstances, an adequate record of the results of the inspec-
tion must be made, and the proper steps taken to see that
the repairs are accomplished by a higher echelon of main-
tenance if necessary.
e. Unserviceable materiel. — Materiel which is unservice-
able or which though serviceable, will rapidly deteriorate if
not promptly serviced, should be tagged with a red tag (OPM
201) . This tag will indicate the defects and the place to
which the item should be taken or sent for repair.
■ 126. Operation of Miscellaneous Items and Accessories
Section. — a. Functions. — This section is charged with the
inspection of all items not included in the materiel inspected
by the other sections, and of all the accessories, spare parts,
instruction materials, and ammunition on hand.
b. Preliminary arrangements. — In order to best accomplish
this phase of the inspection it is best to arrange with the
organization commander to have all this equipment and
materiel displayed In proper order. This will expedite the
inspection and eliminate confusion.
c. Forms. — All of the proper forms must be on hand and
the recorder must be alert to recoTd the findings of the in-
spector or inspectors.
d. Unserviceable, items. — Unserviceable items found as a
result of this inspection should be red tagged (using OFM
201) and replaced.
e. Excess items. — AH items found to be in excess of allow-
ances should be turned in to the appropriate ordnance supply
agency.
Missing items. — All items found to be short of the al-
lowances should in time of peace be requisitioned by the
organization. In the theater of operations such items should
be replaced by the inspecting agency.

127-128
ORDNANCE FIELD MANUAL
Section II
INSPECTION FORMS
■ 127. Inspection Records. — a. Purpose. — Inspection records
are, in the final analysis, only the means to an end. In peace-
time that end is usually the maintenance of adequate rec-
ords for reference and statistical purposes. In wartime, the
need or requirement for inspection records may lessen pro-
gressively as the combat zone is approached until finally in
the combat zone no records of any kind may be kept. How-
ever, if the full value of a type A ordnance inspection (see
par, 114) is to be attained, complete and accurate records of
all phases of the inspection must be kept. In general, the
authority that directs the execution of a type A inspection
will also direct the type of inspection report required.
b. Types of record forms. — The form for an inspection
report may vary from one on which practically the whole
record must be written by the recorder, to one which has
many spaces for special data which may or may not be re-
quired. Obviously, the best form is that which achieves a
nice balance between these two extremes. The ideal form
has special spaces for all essential data, and additional space
for remarks by the recorder or inspector,
c. Preparation of suitable record form. — A few sample
forms of various types are included in this section to illustrate
forms which have been found satisfactory by some inspectors.
The number of forms which would be needed to illustrate one
for each type of materiel would be prohibitive in number for
inclusion in this manual. However, each shop or ordnance
office may, by reference to the pertinent Technical Regula-
tions, and other ordnance publications, develop forms which
will incorporate the requirements for a complete inspection
of any type of materiel.
H 128. Ordnance Office Forms. — a. Description. — O. O. P.
7228, and O. O. P. 7229 (see figs. 14 and 15) are the ordnance
office forms designed for use in submitting reports of inspec-
tion required to be forwarded to organization commanders,
adjutants general, and property and disbursing officers of the
various States, and to the office of the Chief of Ordnance.
O. O. F. 7229 is intended for field use only. Additional in-
structions covering the use of O. O. F. 7228 and O. O. F.
70
ORDNANCE FIELD MAINTENANCE
128-131
7229 are given in figure 16. A suggested code legend for use
on these forms is given in figure 17. This code legend with
any changes considered necessary for particular situations
should be ample for all reauirements.
b. Use for abbreviated reports. — The ordnance office forms
are particularly useful when an abbreviated or digested re-
port of the re'sults of an inspection are required. In such
cases the data for the report may be secured from the detailed
reports, or from inspection tickets.
c. Office that prepares ordnance office forms. — The prepa-
ration of the ordnance office forms for transmission to the
organization to which they pertain, may be accomplished in
the office of the shop which performed the inspection, or it may
be performed in the ordnance office of some higher echelon.
The decision covering this question will rest with controlling
ordnance office.
■ 129. Ordnance Field Manual (OFM) Forms. — The inspec-
tion forms listed herein are intended as samples of type forms
for particular uses, which may be used as basis for the
development of other forms.
■ 130. Use of Red Inspection Tags (OFM 201) (fig. 18). —
Whenever items of ordnance materiel are inspected by shop
personnel, and found to be unserviceable beyond the capacity
of the shop to repair such items, but having such salvage
value*as to make it advisable to send the materiel to a higher
echelon of maintenance the materiel will be tagged with a
red inspection tag, OFM 201. This tag should be completely
filled out, should bear the name of the organization to which
the materiel belongs, the name of the ordnance organization
which inspected the materiel, the name and serial number
of the materiel, the defect, and the date upon which the
materiel was inspected, together with the name of the in-
spector and the signature of the shop officer.
■ 131. Type Small Arms Forms. — a. OFM 202 — Inspection
Report of U. S. Rifle Cal. .30 Ml (fig. 19). — This illustrates
the type of detailed report form which lists specific items
which should be checked by the inspector. The "Sheet No.,"
in the upper right-hand corner refers to the number of each
particular OFM 202 in the total of these sheets in the report.
The "Organization" refers to the organization inspected.

ORDNANCE FIELD MANUAL
6. OFM 203 — Inspection report of Browning Automatic
Rifle, M1918A2 (flg. 20).— This illustrates the type of form
which though it lists two items of essential data, i. e. "Serial
No." and "Condition of Bore," leaves to the inspector or
recorder the task of writing in the details of the defects as
found.
c. OFM 204 — Inspection Report of Machine Gun, Col. .50,
M — (flg. 21). — This illustrates a type of form which consoli-
dates the complete data pertaining to a machine gun, its
mount, and the sighting mechanism pertaining to it. This
form also has a place for the listing of the field service modi-
fication work orders completed. This is frequently of im-
portance. The advantage of this form lies in the fact that
it consolidates all the data pertaining to the weapon. A dis-
advantage lies in the fact that It includes optical instru-
ments and would require close liaison with the instrument
section to Insure that the correct data were entered in the
proper place.
d. OFM 205— Inspection Ticket for Rifle. U. S. Cal. .30. Ml
(flg. 22) . — This illustrates the type of form used as an inspec-
tion ticket, as described in paragraph 122b. Such forms are
detailed in order to save writing on the part of the inspector.
■ 132. Type Artillery Forms. — Artillery inspections forms
are usually more detailed than other forms. This is necessary
because of the amount of technical detail that is involved
in the conduct of a proper inspection of artillery materiel.
a. OFM 206 — Inspection of 75-mm Gun Materiel. M1897-
M4 (fig. 23). — This illustrates the type of form used for the
recording of specific details. It should be noted that it con-
tains in appropriate places, notes of certain facts of interest
both to the inspector and to the inspection reviewer.
b. OFM 207 — Inspection Report of 37-mm Gun Materiel
(other than Artillery Units) (fig. 24) . — As in the case of OFM
204. this report consolidates on a single sheet, important
information concerning all the essential materiel required
to operate the weapon. Such a form is best used by an expe-
rienced artillery inspector, who has no need for the detailed
list of items requiring inspection.
c. OFM 208 — Inspection Report of Mortar, M — (flg. 25) . —
This form is Included because it illustrates a use for this
78
ORDNANCE FIELD MAINTENANCE
132-134
type of form which is particularly appropriate. The mortar
is essentially so simple as to require few detailed reminders
to insure a complete inspection.
d. OFM 209 — Inspection Report of Artillery Vehicles
(fig. 26) . — As will be noted, this form has been set up to
care for the equipment in the hands of a particular unit.
There should, in the case of each item of equipment listed,
be sufficient lines to accommodate the number of items in the
hands of the organization to be inspected.
■ 133. Type Automotive Forms.— Forms for the use of the
automotive section may vary from the detailed technical
inspection report such as QMC Form, No. 260, to general
check lists designed for a rapid check of the materiel by the
inspecting party in the field.
a. QMC Form No. 260 (figs. 27 and 28).— This is a complete
form suitable for a shop inspection of all types of ordnance
automotive materiel, including combat vehicles.
b. OFM 210 — Ordnance Vehicle Check List (fig. 29) . — This
is an example of a special check list prepared for use in the
field for the quick inspection of a particular type of auto-
motive equipment, in this case a scout car. It is designed to
guide the inspector to every critical point on the machine
which has been or may be expected to be a source of trouble.
The preparation of such a form is the product of experience.
The best form will usually be the one which is kept up to date
in the light of such experience.
■ 134. Type Instrument Forms. — Because of the limitations
on the extent to which many instruments may be disassembled
in the field, instrument inspection forms will in general not
contain the detail that might otherwise be required.
a. OFM 211 — Inspection Report, Instruments or Sighting
Equipment (fig. 30). — This is a general form designed to illus-
trate some of the items which a detailed inspection form
might list.
b. OFM 212 — Inspection Ticket for Fire Control Materiel
(fig. 31) . — This form is included as an illustration of the type
form which may from time to time be required in field
operations.
c. OFM 213 — Instrument Report (fig. 32) . — This is a type
report designed for a particular piece of materiel. It lacks
79
134-135
ORDNANCE FIELD MANUAL
detail as regards the instrument itself. However, it covers
fully the condition of all accessories.
d. OFM 214 — Inspection Report of Fire Control Equip-
ment (units other than Field Artillery) (fig. 33). — This form
■ § I

consolidates on a single sheet the information concerning all
the fire control equipment pertaining to a given organization.
■ 135. Type Forms for Inspection op Miscellaneous Items,
Accessories, and Ammunition. — These forms are designed to
80
ORDNANCE FIELD MAINTENANCE
135
assist In the checking of the subject items pertaining to major
items of ordnance in the hands of organizations.
a. OFM 215 — Check List of Accessories, Spare Parts, and
Instruction Material for Rifle, Cat. 30, Ml (figs. 34 and 35) .—
This form illustrates the detail that is necessary for a com-
plete check of the items pertaining to major items of ordnance
materiel. Notice that the note numbers provide flexibility
in Indicating the proper quantities in the authorized column.
6. OFM 216 — Inspection Report of Ammunition and Am-
munition Components (fig. 36) .—This form is used chiefly in
peacetime and in the zone of the interior for checking the
81
135-136

basic loads of ammunition in the hands of the troops. It
should be used in connection with the latest revision of
Ordnance Field Service Bulletin, 3-5. Particular attention
should be given to all grade 3, cal. .30 and cal. .50 ammunition,
and to all "RT" cal. .45 ammunition. Ammunition which is
not positively identified should be graded as grade 3 and re-

Section I
GENERAL
■ 138. General. — Part two is a discussion of the various
functions and operations of a maintenance company. It is
of such a nature as to be applicable to any one of the several
types of maintenance companies, and when considered in
conjunction with part one and other pertinent parts of this
manual, affords a thorough discussion of such an organiza-
tion. It is necessary that the reader use proper judgment in
applying this information to his particular situation.
■ 139. Mission. — The mission of the maintenance company
is the provision of ordnance service to the troops. This does
not include the supply of ammunition.
■ 140. Ordnance service. — Ordnance service, as provided by
the maintenance company, includes all activities that may
be necessary to maintain in serviceable condition the ord-
nance materiel of units which it Is assigned to support. This
extends to inspection, repair, manufacture or fabrication,
storage and issue of ordnance general supplies, and any other
activities that properly come within the province and limita-
tions of the equipment and personnel of the organization.
(See FM 9-5.)
■ 141. Additional functions. — The maintenance company
will also, when occasion demands —
a. Inspect and repair salvaged ordnance materiel.
99
141-143
ORDNANCE FIELD MANUAL
b. Arrange for the transportation to the rear of any
materiel which cannot be repaired or which will not be
required for reissue.
c. Conduct any schools that may be necessary to instruct
the combat units in the proper care and technical use of
ordnance materiel.
d. Repair any motor vehicles brought to it for repairs.
(See AR 850-15.)
■ 142. Supply. — a. How effected. — The supply of a main-
tenance company in a battalion is effected through the bat-
talion supply officer, who prepares such requisitions and con-
solidations of requisitions for supplies for the battalion as
he may find to be necessary. These requisitions, when ap-
proved by the officer designated by the army ordnance officer,
are transmitted to the ordnance supply agency designated to
support the battalion.
t>. Supply in zone of the interior. — In army or corps ord-
nance battalions in time of peace or in the zone of the
interior, the battalion supply officer does not prepare requisi-
tions or consolidations of requisitions. In this case he trans-
mits the requisitions prepared by the companies to the proper
supply agency (retains a copy for his file) and takes such steps
as may be necessary to insure prompt delivery of all such
supplies requisitioned.
c. Local procurement of supplies. — It will sometimes hap-
pen that items required in maintenance operations of ord-
nance companies may be procured locally. This will be
particularly true of such items as certain types of automotive
parts, lubricants, cleaning and preserving materials, and
metal stock. Whenever such procurement can be effected, it
should be done.
■ 143. Flow of Requests fob Ordnance Supplies. — a. Troop
units. — Troop units request supplies from the contact parties
serving them or directly, by requisition, from the proper ord-
nance officer, division, corps, or army, as the case may be.
The proper ordnance officer will effect necessary supply In
one of the following ways:
(1) Issues from stock under his control.
(2) Requisition on the next higher echelon.
100
ORDNANCE FIELD MAINTENANCE
143-146
(3) In conformity with any special Instructions on the
subject as issued by the army commander.
b. Ordnance contact parties. — Normally the supply of the
contact parties of the various echelons Is effected by the
proper ordnance officer. However, circumstances will often
make it advisable that they supply one another, as far as
possible, with any spare parts urgently needed. In general,
the field supply of ordnance items Is very flexible, and requires
the cooperation of all ordnance personnel.
C. Army service area. — Ordnance supplies are moved into
the combat zone as the result of requisitions placed by the
army ordnance officer or the army depot officer against credits
in communications zone supply installations. The supplies
may be stocked in the army ordnance depot or may be routed
direct to the using unit.
■ 144. Planning. — Maintenance company commanders must
continually plan to meet foreseen and unforeseen contingen-
cies. Paragraph 3 is entirely applicable in this respect.
■ 145. Assignments. — For a complete discussion of the as-
signments of maintenance companies, see FM 9-5.
Section II
ORGANIZATION AND EQUIPMENT
■ 146. Organization. — a. Requirement. — The organization
tables of maintenance Companies have been designed with a
view to having within each company numbers of trained
personnel and quantities of specialized equipment sufficient
to handle the type load represented by the equipment of the
unit each is designed to support. See figure 37 for a chart of
the general organization of maintenance companies.
o. Flexibility. — The internal organization of a maintenance
company as prescribed in the Tables of Organization is not
to be considered as a rigid requirement, which must be adhered
to under all circumstances. Changes in the strengths of sec-
tions, the assignments of duties, and the disposition of grades
and ratings, in accordance with the personalities and skills
available to him, must be made by the company commander
to best meet the requirements imposed by the problems con-
fronting the company.
101
146
ORDNANCE FIELD MANUAL
102
ORDNANCE FIELD MAINTENANCE
146-149
c. Shop organization. — The organization of maintenance
company shops is based on the Tables of Organization of the
companies, with such modifications as may be necessary
on account of factors such as —
(1) Availability of properly trained personnel.
(2) Loads in the various sections. (See flg. 1.)
■ 147. Equipment. — A complete list of all of the equipment of
a maintenance company may be obtained from Table of
Basic Allowances No. 9.
■ 148. Company Armament. — All ordnance maintenance com-
panies are armed. The types of weapons assigned to par-
ticular companies are governed by the type of the company.
For details pertaining to this equipment, see Table of Basic
Allowances No. 9. In emergencies, full use should be made
of att weapons on hand, for which ammunition should be kept
available.
■ 149. Automotive Equipment — The automotive equipment
furnished a maintenance company is of two general types:
General purpose vehicles furnished by the Quartermaster
Corps and special purpose vehicles furnished by the Ordnance
Department, For details of assignment to particular main-
tenance companes, see latest Table of Basic Allowances No. 9.
a. General purpose vehicles include the following:
Vi-ton truck.
Command and reconnaissance truck.
Cargo trucks.
Trailers.
Pick-up trucks.
As these vehicles are common throughout the Army, no de-
scription of them will be given here.
b. Special purpose vehicles include the following:
Truck, artillery repair.
Truck, automotive repair.
Truck, emergency repair.
Truck, instrument repair.
Truck, machine shop.
Truck, small arms repair.
Truck, spare parts.
Truck, tank maintenance.

Section in
SUPPLY FUNCTIONS OP COMPANY
■ 150. General. — Except when assigned to army troops when
a depot is established, one of the missions of the maintenance
company is the supply of cleaning and preserving materials,
and a small quantity of maintenance parts, accessories, and
major items. In general, the amount of these supplies carried
by the company should be adequate to support its share of
the maintenance load for a definite period of operation de-
pending upon the time lag of supply. In order to accomplish
this supply mission careful planning is essential. Careful
daily scrutiny of the stock record account, the shop expendi-
ture record, and the truck bin cards is necessary.
■ 151. Basic Load. — a. General. — In addition to the organ-
izational and individual equipment authorized by Table of
Basic Allowances, the maintenance company will have on hand
a basic load of ordnance supplies. The transportation facil-
ities of the company put a very definite limit on the stock of
these supplies which may be carried. Within this limit of
transportation facilities the company commander has the re-
sponsibility for determining what quantities of what items will
be carried. The factors affecting the ratio of various supplies
which will be stocked include: the types of weapons in the
organizations being serviced, the mobility and mission of the
combat troops, the terrain expected, and the time element
necessary for resupply. (See appropriate SNL's, ordnance
storage and shipping charts, and ordnance equipment charts.)
b. Maximum-minimum stocks. — When the company com-
mander has determined the ratio of various supplies that will
be carried, he then will assign the maximum quantity of each
that shall be on hand at any one time. Also he shall set a
minimum, quantity (based on time of resupply) below which
the stock on hand should never fall, without a requisition
104
ORDNANCE FIELD MAINTENANCE
151-152
having been placed. These maximum-minimum figures will
be the stockman's guides as to when to reorder each item, and
the quantities to be requisitioned.
* 152. Computation of Stocks of Supplies. — The addenda to
the SNL's include the estimated quantities of major items,
maintenance parts, and equipment for the maintenance for 12
months within the theater of operations of a specified num-
ber of major items. For example: SNL No. A-6 for caliber
.30 machine gun M1919A4 has in its addendum the quantities
of major items, maintenance parts, and equipment estimated
to be necessary to maintain 100 of these guns in the theater
of operations for 12 months. The actual parts to be carried
by a maintenance company will be based on this addendum,
subject to a consideration of the particular mission involved,
past experience with the using troops, time lag for resupply,
and organic transportation facilities available.
a. Entire addendum not necessary. — (1) No company will
ever normally require all parts listed in any particular
addendum, in the exact (total) quantities specified, which are
an estimated 12 months' stock.
(2> The company commander must determine the num-
ber of major items to be maintained. For that number of
items and considering the time of resupply, he can refer to
addenda of the appropriate SNL's and compute the approxi-
mate number of items needed. Modifications of these esti-
mates may be justified on the basis of his past experience with
the organization or the nature of the particular mission in-
volved. It would not be unlikely that the number of items
believed necessary will be in excess of the company's organic
transportation facilities. If this is the case, the balance must
be boxed and shipped in bulk to a convenient resupply point.
b. Illustrations. — Two extreme cases illustrating the ap-
plication of this addendum to the servicing of 100 caliber .30
machine guns M1919A4 are cited below, as follows:
(1) A maintenance company stationed at an army post,
with a supply warehouse across the street from the shop,
Would in all probability requisition items only as they are
needed in daily maintenance work on the 100 guns, regard-
less of the specifications in the addendum.
(2> A maintenance company assigned to a task force with
100 such guns at an Isolated station with a 90-day time lag
105
152-154
ORDNANCE FIELD MANUAL
for resupply would require a much larger number of items.
It is probable that for the 90-day period he would need about
half of the 12-month supply for 100 guns, of each item listed
in the addendum to SNL A-6.
e. References. — In addition to the SNL addenda, other
references will assist the company commander in working
out his estimates of necessary loads. He should also refer
to —
(1) Ordnance equipment charts for tables of equipment
for the organization the company is servicing.
(2) Ordnance storage and shipping charts for determina-
tion of weight and bulk of items that must be transported
either on organic transportation facilities or by some other
method.
(3) SNL K-I and K-2 for cleaning and preserving
materials.
d. If addendum not available. — Addenda including the
above data are being prepared for all outstanding SNL's, but
if any particular addendum with this data is not available,
the estimate of the company's requirements will be a matter
for the good judgment of the company commander concerned.
■ 153. Minimum Stocks. — In order that the Ordnance De-
partment at large may be able to make equitable distribution
of the total stock of any one item, company commanders
should limit their requisitions and stocks to the absolute
minimum requirements that are estimated to be necessary for
each contemplated situation. For example:
A company so located that resupply can be effected within
48 hours should normally carry a considerably reduced basic
load of parts and supplies. Similarly, company commanders
should request stocks of parts and supplies for only those
weapons which they will be called upon to maintain, as per
Ordnance Equipment Charts available for each line organi-
zation.
■ 154. Issue of Supplies. — a. In time of peace or in zone of
the interior. — (1) Replenishment of organizational equip-
ment by using arms and services should be accomplished as
prescribed in AR 35-6540. (See aiso Cir. No. 147, W. D.,
1940.)
106
ORDNANCE FIELD MAINTENANCE
154-156
(2) Replenishment of supplies in the ordnance company
is accomplished by requisition on the next higher ordnance
echeion. In the field army, replacement of maintenance
parts, accessories, and major items are generally obtained
from the army depot.
b. In time of war. — (1) Organizational equipment is issued
by the ordnance company to using arms and services as pre-
scribed in section VT, chapter 2, FM 100-10.
(2) The procedure for replenishing supplies in the ord-
nance company is substantially the same as in time of peace.
<See par. 97a(2) .)
■ 155. Dropping op Property From Ordnance Property Ac-
count. — o. In time of peace or in zone of the interior. — (1)
Expendable property is dropped from ordnance property ac-
counts in the manner prescribed in AR 35-6620. (See also
Cir. No. 33, W. D., 1941.)
(2) Nonexpendable property is dropped from ordnance
property accounts in the manner prescribed in AR 35-6620.
(See also Cir. No. 38, W. D., 1941.)
(3) The expandability or nonexpendability of property
i.iay be determined by reference to the appropriate SNL.
b. In time of war — in theater of operations. — (1) In the
combat zone records of property accountability are normally
dispensed with.
(2) In the communications zone such records of property
accountability will be kept as are ordered by the officer com-
manding that theater of operations.
■ 156. Property Accountability. — a. General. — All public
property whether acquired by the War Department or the
Army at large, by purchase or by transfer from other agen-
cies of the Government, and whether paid for or not, must
be accounted for on an appropriate property account. (See
AR 35-6520; see also Cir. No. 147, W. D., 1940.)
b. In time of peace and in zone of the interior. — Unless
the company is in the theater of operations, durinir war, this
stock record account will be diligently and properly main-
tained, and property will not be dropped from the record
without a proper supporting voucher.
c. In theater of operations, communications zone. — In the
communications zone of the theater of operations, the degree
107
156-157
ORDNANCE FIELD MANUAL
to which accurate and proper records and supporting vouch-
ers are maintained will be determined by the officer com-
manding that theater of operations. The use of supporting
vouchers to drop property from the stock record account will
not be discontinued at the discretion of the company com-
mander in the communications zone.
d. In theater of operations, combat zone. — In the theater
of operations, the stock record account need not be kept in
the combat zone, where all items issued are replaced promptly
and without regard to expendabiiity or nonexpendability of
the item.
e. Changes in property accountability. — Pursuant to AR 35-
6520, also Circular No. 134 War Department, 1941, and also
paragraphs 520, 521, and 522, FM 100-10, accounting for prop-
erty will change as the organization responsible for the prop-
erty moves into or out of the zone of the interior, the
communication zone, or the combat zone.
■ 157, Property Responsibility. — a. All company property,
of whatever nature, is the responsibility of the company com-
mander. It is his duty to safeguard such property against
loss or destruction at all times.
b. Over, Short, and Damaged Report. — When material re-
ceived is incomplete or damaged, or shipped under improper
nomenclature, an O. S, and D. report, W. D. QMC Form No.
445, should be reported in accordance with AR 35-6560, and
Circular No. 38, War Department, 1941.
c. Since it is impracticable for one person to exercise the

An immediate report should be made to the shop officer or
company commander whenever there exists evidence of such
