INFANTRY FIELD MANUAL 

ANTITANK COMPANY, RIFLE BEGIMENT 
Section I 
DOCTRINE 

■ 1. General Methods of Antitank Action. — a. The ac- 
tion of antitank units must be included with the action 
of other combat elements, both in attack and in defense. 
In approach march and attack, the movements and positions 
of antitank units must be coordinated to insure protection of 
the attacking troops and their reserves against counterattack. 
In defense they cover the main line of resistance and favor- 
able avenues for tank approach, or are grouped with Infantry 
reserves and armored units for the support of counterattacks. 
The employment of antitank units as independent defensive 
elements and their distribution with a View to covering every 
possible avenue of tank approach or to affording immediate 
protection to all echelons of the forces lead to uncoordinated 
action and a dispersion of the means of antitank defense with 
consequent loss of effectiveness. The employment of antitank 
units must be included in the general plan of action of the 
entire force. 

b. Within the limitations fixed by the location and mission 
of the troops, the terrain dictates the distribution of antitank 
gun units. 

c. The defense of a position against an enemy force, includ- 
ing armored units, comprises two main elements: 

(1) Tactical localities organized in depth and garrisoned 
for the defense of the main line of resistance and including 
the antitank units (reinforced when necessary) of the front 
line regiments and passive antitank means such as mines and 
obstacles. 

(2) Reserves of large units held out for counterattack and 
including foot infantry, armored units, and antitank units. 

d. Where the organized localities, including active and pas- 
sive antitank means, do not succeed in stopping the attack, 
they disrupt, retard, and canalize the attacking armored units 



1 



1-2 



INFANTRY FIELD MANUAL 



and thus create conditions favorable for counterattack by the 
intact defensive reserves. The reserve antitank units occupy 
positions in such manner as to afford protection against hostile 
tanks, and to disrupt further and canalize the tanks into 
zones where they may be effectively dealt with by the counter- 
attacking forces and other planned active and passive meas- 
ures. The location of antitank mines and obstacles must be 
known to counterattack forces, especially friendly mechan- 
ized elements. Whenever practicable the location of mine 
fields and obstacles should be coordinated in advance with 
counterattack plans. 

■ 2. Training. — a. Members of the antitank company are 
trained as individual soldiers and as operators of crew-oper- 
ated weapons in accordance with PM 7-5. All members of 
the company are trained to operate motor vehicles and the 
automatic rifle against air or ground emergency targets. 

b. Antitank units are trained with tank units, both as 
friendly and hostile forces. They are trained to recognize 
the strong and the vulnerable features of tanks, their dis- 
tinguishing characteristics, and combat methods. Com- 
manders impress on their men that the tank crew's limited 
field of vision Increases the value of cover and concealment; 
that flight before armored vehicles invites certain destruc- 
tion; and that a tenacious spirit and accurate delivery of 
fire give gun crews every chance of success. They are taught 
that premature opening of fire may disclose the gun posi- 
tions and result in neutralization before the gun crew can 
accomplish Its mission, and that the fight between them 
and the armored foe lasts only a few minutes and will be 
decided principally by their skill and moral stamina. They 
are trained to estimate the practicability of terrain for tank 
movement and the relative effectiveness of antitank obsta- 
cles. 

e. Training in driving over varied ground is conducted to 
teach chauffeurs to estimate the clearance of the vehicle and 
piece and the degree of angular turn, and to facilitate hasty 
occupation of positions and rapid displacements. Care must 
be emphasized in operating over rough terrain to preclude 
injury to the vehicle and piece. 

d. When moving in the combat area the prime movers (or 
weapon carriers) follow their leader with 50 yards to 100 yards 



2 



ANTITANK COMPANY, RIFLE REGIMENT 



2-3 



distance. If the vehicle ahead halts, others halt, keeping 
their distances unless signalled to close up. As vehicles halt 
they draw off the road or trail and stop under a tree, against 
a bush, or behind any nearby cover. If possible they stop in 
a shadow. If the leader directs or signals "take cover," the 
trucks endeavor to get behind walls, buildings, banks, or into 
depressions which give better cover from fire and view. A 
few branches are habitually carried to break the outline of 
the vehicles and guns if they are forced to halt in the open. 
Guns and vehicles are parked or concealed so that they may 
readily resume the march. 

e. Over rough ground or hard going the men dismount and 
follow their vehicles, helping if necessary. One man leads 
to pick a route. At night he carries a dimmed light for the 
driver to follow. 

/. Covered routes are sought. Edges of woods, scattered 
buildings, or trees contribute to concealment. Open crests 
are avoided. When forced to cross a crest, a place is sought 
where the outline is broken by trees, houses, etc. 

g. In unfamiliar terrain the leader should proceed (with 
a connecting file and on foot, if necessary) to select a route. 

h. When moving to positions not fully protected by other 
troops, vehicles advance by bounds, each bound being recon- 
noitered by a single vehicle or man on foot or motorcycle be- 
fore the others are signalled forward. 

■ 3. Combat Information and Orders. — Each antitank unit 
commander passes on promptly to his subordinates the fol- 
lowing : 

a. Enemy information. — Emphasize the latest identification 
and reports concerning the movements of tanks and other 
motorized forces. 

b. Information of our own and supporting troops. — Loca- 
tion, identification, and proposed employment of friendly 
troops, especially of mechanized and other motorized forces. 
Missions and locations of nearby antitank weapons, adjacent 
and supporting units. Location of mines, natural and arti- 
ficial obstacles. 

c. Mission of unit. — Indicate the troops, Installation or 
terrain feature to be protected. Assign sectors when ap- 
plicable.

d. Miscellaneous. — Arrangements for local security, am- 
munition and ration supply, alternate positions, supplemen- 
tary positions, prime mover positions, warning service, position 
in readiness, prearranged signals and communications. 

e. Location of — 

(1) Aid stations. 

(2) Ammunition distributing point. 
<3) Command post. 

■ 4. Local Security and Warning Service. — a. Antitank unit 
commanders make provisions for the local security of their 
units and prearrange an effective warning system. On route 
march and approach, In bivouac, in assembly areas, and in 
combat constant vigilance and sure means of communication 
and warning are maintained to preclude surprise and to in- 
sure timely and effective operation of the guns. Antitank 
units coordinate with nearby friendly troops in regard to local 
security, communications, and warning service. Relay posts 
are required frequently in the transmission of signals. Air 
and motor reconnaissance units usually give the first warning 
of the presence of hostile tanks in the vicinity of the unit. 
To give warning of the approach or presence of hostile air- 
craft, mechanized or ground attack, three long blasts of 
whistle or vehicular horn repeated several times, or three 
equally spaced shots with rifle or pistol, or three short bursts 
of fire from machine gun are prescribed. In daylight the 
person giving the signal indicates the direction of the im- 
pending danger. At night or during daylight if necessary 
the alarm signal will be supplemented by voice to indicate 
the direction of the danger. 

b. In moving situations vigorous and continuous recon- 
naissance are conducted. Badio and prearranged signals are 
employed to maintain communications and to give timely 
warning. 

c. An antitank unit in a position in readiness establishes 
observation and warning posts throughout its area of re- 
sponsibility at such distances as to insure the timely arrival 
of gun units at their firing positions. There must be sure 
communications between the unit and its observation and 
warning posts. Sound-powered telephones or voice radio may 
be used where antitank elements are not too widely separated. 

d. In defensive situations where antitank observation and 



4 



ANTITANK COMPANY, RIFLE REGIMENT 4-7 

warning posts are connected with a signal communications 
system, their warning calls are given priority. 

Section n 

CHARACTERISTICS OF 37-MM GUN AND GUN 
POSITIONS 

■ 5. Technical Characteristics. — The 37-mm gun is the prin- 
cipal weapon of the regimental antitank company. Its more 
important characteristics are — 

a. High velocity and flat trajectory. Effective penetration 
up to 1,000 yards against light and medium tanks and against 
concrete emplacements 2 feet thick. Accuracy of fire against 
moving targets falls off greatly beyond 1,000 yards. 

b. A practicable rate of fire of approximately 10 rounds per 
minute. Rate of fire is influenced more by observation of 
effect than by the mechanical properties of the piece. 

c. Relatively wide traverse (60°) in comparison with cannon 
designed for other missions. 

d. High mobility both on roads and cross country. 

e. Limited capacity for movement by hand, with slope- 
climbing ability of about 30° on firm soil. 

/. Limitation to direct fire methods from open positions. 
g. Great vulnerability in movement In the zone of infantry 
fire and considerable vulnerability in firing position. 

■ 6. Tactical Limitations. — a. The foregoing characteristics 
of the piece limit Its fire to short periods and make necessary 
provision for alternate positions. 

b. Long range fire against individual targets may subject 
gun positions to premature disclosure. However, such action 
may be very effective in covering defiles and other points of 
obligatory passage. 

c. Dependence of antitank guns on the prime mover for 
movement in displacements and the vulnerability of the prime 
mover in exposed movement frequently require the guns to 
await the capture of a terrain mask before commencing a 
displacement. Wherever practicable, such delays in displace- 
ment are avoided by the use of covered routes even where 
considerable detours are required. 

■ 7. Position. — The antitank gun and prime mover occupy 
positions in action or preparation for action as follows: 



5 



7 



INFANTRY FIELD MANUAL 



a. Fire positions are occupied by the gun in action to cover 
an assigned sector of fire or a potential avenue of approach. 
Firing positions are primary, alternate, or supplementary. . 

(1) Primary position is the firing position offering the best 
conditions for the accomplishment of the gun's mission. 

(2) Alternate position is a firing position from which the 
same fire missions can be executed as from the primary 
position. 

(3) Supplementary position is a firing position from which 
the gun can accomplish secondary fire missions other than 
those to be accomplished from primary or alternate positions. 

b. A cover position close to the firing position (within 100 
yards) may be selected to provide cover and concealment for 
the gun and crew. In open terrain artificial cover and con- 
cealment are provided. When the observer signals an ap- 
proaching target the gun is moved rapidly to the firing posi- 
tion. A cover position is only resorted to when cover cannot 
be found or provided at the firing position. 

c. Uncoupling position is the point at which the gun is 
uncoupled and moved by hand to the firing or cover position. 
It should be under cover and as near as possible to the firing 
position. 

d. Truck assembly area is a location under cover occupied by 
prime movers of an antitank gun unit when the pieces are 
in firing or cover positions. In moving situations it should be 
close enough to the firing position to permit communication 
by arm and hand signals and reduce the manhandling of 
ammunition to a minimum. 

e. Alternate positions are subject to the same requirements 
as primary positions and cover the same fire sector. They 
must be accessible from the primary position by manhandling 
guns under cover from enemy observation. They must be 
located far enough (at least 50 yards) from the primary posi- 
tion to avoid being included in the radius of effect of fires 
directed on the primary position. 

/. Positions in readiness add flexibility to antimechanized 
weapon defense and are used when available antitank means 
are inadequate to occupy positions covering an extended area 
or several avenues of approach. Gun units are concealed in 
a centrally located area, alert to move quickly to meet the 
hostile attack. Everything possible to insure timely employ- 
ment of the guns is accomplished in advance, to include selec- 



6 



ANTITANK COMPANY, RIFLE REGIMENT 7-11 

tion of positions and routes thereto. Units in a position in 
readiness keep pieces coupled, motors warmed, and in urgent 
situations, crews entrucked. 

g. In selecting a firing position, the gunner must be able to 
see and the gun must be able to Are into the area or sector 
assigned. 

(1) In covering a road, the gun should be sited to fire on a 
portion where movement is restricted by ditches, banks, heavy 
woods, or similar obstructions. The gun is located and con- 
cealed so that hostile patrols operating along the. road will 
not find it and so that hostile interdiction fire on a road will 
not normally include the gun position. 

(2) In attack, positions on high ground with wide fields of 
Are and view are sought. Trucks are kept close at hand. 
Cover and concealment may have to be sacrificed to provide 
the best field of fire and ability to move. 

(3) In defense, maximum concealment and positions cover- 
ing definite avenues of approach are sought. Trucks may be 
sent well to the rear if necessary for effective cover. An 
emplacement for the gun should be prepared if it can be con- 
cealed, and slit trenches for the crew should be dug in the 
immediate vicinity. 

Section III 
ANTITANK GUN SQUAD 

■ 8. Reference. — For mechanical training, gun drill, and 
technique of fire see FM 23-70. For basic training of indi- 
vidual soldier see FM 7-5. For training with motor transpor- 
tation see FM 25-10. 

■ 9. Composition. — The 37-mm antitank gun squad com- 
prises a corporal, gunner (No. 1), assistant gunner (No. 2), 
chauffeur, and one or more ammunition carriers. 

■ 10. Equipment and Transportation. — The equipment 
of the squad comprises one 37-mm antitank gun, with 
accessories necessary to keep it in action, and one prime 
mover, a truck which tows the gun and carries the crew, 
accessories, and ammunition. 

■ 11. Duties. — All members of the squad are trained to as- 
sume the duties of any other member of the squad. For 
detailed duties see FM 23-70. 



7 



12-43 



INFANTRY FIELD MANUAL 



■ 12. Movement. — a. Movements from cover to firing 
positions or from primary positions to alternate positions are 
usually executed by hand. Movement from primary to sup- 
plementary positions may be executed coupled or by hand, 
depending on the distance separating the positions. Move- 
ments from positions in readiness to firing positions are usu- 
ally executed coupled. 

o. On the march and in cross-country movement, the prime 
mover is used to tow the gun and to carry the crew, ammuni- 
tion, and accessories wherever the situation permits. On 
extremely difficult terrain the men dismount, assisting the 
vehicles when necessary. The squad leader often precedes 
his vehicle on foot to select the route and avoid obstructions. 

■ 13. Occupation of Firing Position. — a. Reconnaissance 
prior to the occupation of the position is conducted as in- 
conspicuously as possible. 

b. The squad leader designates the exact location of the 
firing position in the approximate area assigned by the sec- 
tion leader. He locates the cover position and directs the 
movement of the piece thereto from the uncoupling position. 
He supervises the preparation of the gun emplacement and 
shelter for the crew and takes all practicable measures for the 
concealment of the gun emplacement and posts of the crew, 
and clearance of the field of Are. Sufficient ammunition for 
prospective fires is laid down at the emplacement. When 
action is impending it may be advisable to set up the gun in 
the first reasonable position that is found so that the gun can 
fire if tanks appear before the reconnaissance for the final 
position is completed (see fig. 1). 

c. The position is prepared so that the piece can cover the 
entire assigned primary sector by its maximum limit of 
traverse. If natural obstacles do not exist, the immediate 
approaches to the position are blocked by artificial obstacles 
where practicable. Ammunition at the emplacement is so 
located as to avoid interference with the service and move- 
ment of the piece. 

d. Measures for concealment are of extreme importance in 
the preparation of a position from which fire is not to be 
opened immediately. The gun is covered with the camouflage 
net or natural camouflage in both firing and cover positions. 



8 




9 



13-14 



INFANTRY FIELD MANUAL 



Measures are taken to avoid or minimize the effects of muzzle 
blast and flash. 

e. Whenever effective concealment in the firing position is 
impracticable, the squad initially occupies a cover position 
while the squad leader observes and prepares the firing data. 
The crew moves the gun Into the firing position and prepares 
for action on the squad leader's order. 

/. In the prolonged occupation of a position, reliefs of 
observers are established. Observation is so organized as to 
cover the fields of view to the front and to the flanks and 
rear of the position. 

■ 14. Fire Control. — a. Unless the section leader has re- 
served to himself the opening of fire, the squad leader exer- 
cises fire control in accordance with his general instructions. 
He opens Are on targets appearing in the squad primary sec- 
tor of Are when they arrive within the range limits fixed by 
the section leader. Similarly he opens Are on targets ap- 
pearing in secondary sectors under conditions fixed by the 
section leader. He makes certain of the identification of the 
target as an enemy vehicle. 

b. Where emplacements of the section guns are located 
close enough to permit section control, the section leader may 
reserve the opening of fire and also the shifting of fire to 
other sectors. 

c. After the squad leader's order to open fire, the gunner 
selects successive targets in the assigned fire sector on his 
own initiative. 

d. Fire once opened is not interrupted during the progress 
of a tank attack. Short, quick changes of position may be 
necessary to facilitate firing or to meet a flank attack. 

e. Alternate positions are occupied when enemy action 
makes fire from the primary position impracticable. In squad 
training, the movement of the piece to the uncoupling posi- 
tion, the uncoupling of the piece and movement into firing 
and cover positions, change of direction of fire, movement 
into alternate positions, and coupling of the piece are inten- 
sively practiced so as to reduce the time required for these 
operations. 

/. The squad leader must at all times be informed as to 
the ammunition supply and the possibilities of replenishment. 
He signals for replenishment in time to avoid depletion of 
the supply at the gun. 

10 



ANTITANK COMPANY, RIFLE REGIMENT 15-19 

■ 15. Displacement.— -a. In attack the squad executes dis- 
placements to uncoupling positions designated by the section 
leader. Movement over open ground is executed coupled at 
as rapid a rate as the nature of the ground permits. Advan- 
tage is taken of available cover to mask the movement. The 
squad leader executes reconnaissance of the firing positions 
and routes leading thereto, and directs the movement of the 
piece from the uncoupling position to cover position and the 
preparation of the firing position. 

b. Displacements in retrograde movements are effected in 
accordance with the methods indicated for the attack. 

Section IV 

RIFLE SQUAD 

■ 16. References. — For basic training of a soldier and the 
rifle squad see FM 7-5. For technique of fire, rifle and auto- 
matic rifle squad, see FM 23-5 and FM 23-15. 

■ 17. Composition. — a. The squad comprises a sergeant 
(squad leader) , a corporal (second in command) , a chauffeur, 
automatic riflemen, assistant automatic riflemen, and several 
riflemen. 

b. Its organization and equipment permit the formation of 
two automatic rifle groups, each consisting of a noncom- 
missioned officer, automatic rifleman, assistant automatic 
rifleman, and riflemen for attachment to antitank gun sec- 
tions as required. (For further details see app. I.) 

B 18. Equipment and Transportation. — Individual armament 
includes automatic rifles and rifles. A truck is assigned for 
the transportation of the squad. Intrenching tools, dis- 
tributed in the ratio of 5 shovels, 3 pick mattocks, 1 axe, and 
1 wire cutter to every 10 men, are carried in the squad trans- 
portation. 

■ 19. Mission.— o. The principal mission of the squad is the 
protection of the guns in position against the attack of foot 
or motorized elements, and in protected postion areas the 
extension of the warning service. 

b. In detached missions of the antitank platoon or section, 
the squad or an automatic rifle group may form part of a 
security detachment covering the movement. 



11 



20-22 



INFANTRY FIELD MANUAL 



■ 20. Employment. — a. The squad is distributed to sections 
by automatic rifle groups when sections are assigned detached 
missions. 

b. In the defense of antitank gun positions, the squad is 
employed as a unit under the direction of the platoon leader 
or distributed by group to the sections. Unit employment is 
indicated where the situation favors covering the platoon 
front by cross flres of the automatic rifles. Where visibility 
is restricted or the platoon covers a wide front, automatic 
rifle group distribution to sections is usually necessary. 

c. Where practicable the rifle squad precedes the gun units 
in the occupation of a position. In the echeloned displace- 
ment of the platoon in attack, the squad (under platoon con- 
trol) usually displaces by groups. 

d. The platoon leader coordinates the squad dispositions for 
the protection of a position with nearby troops. When sec- 
tions of the position are adequately protected by other troops, 
the squad is employed to extend the warning service. An 
exposed flank may require the employment of the entire squad 
for flank protection. 

e. The rifle squad leader insures that the members of the 
squad understand the squad mission (see par. 3) . 

/. Available riflemen assist the antitank gunners in the 
preparation of firing positions, and where necessary in the 
movement by hand of ammunition for the piece. 

Section V 
ANTITANK GUN SECTION 

■ 21. Composition. — The 37-mm antitank gun section com- 
prises a sergeant (section leader) , a chauffeur, and" two anti- 
tank gun squads. 

■ 22. Equipment and Transportation. — a. The section in- 
cludes two 37-mm antitank guns and three prime movers. 
The section leader is armed with a pistol and is equipped with 
field glasses. The chauffeur is armed with a rifle and 
equipped with compass. Intrenching tools are distributed 
and carried as indicated for the squad. 

b. Two prime movers draw the guns and transport the gun 
squads, accessories, and ammunition. The third (section 
truck) carries the section leader, chauffeur, and ammunition. 



12 



ANTITANK COMPANY, RIFLE REGIMENT 22-24 

and is a reserve prime mover. When the gun squads are 
not operating on separate missions, ammunition carriers may 
be transported on the section truck available to handle am- 
munition. An automatic rifle is provided with each section 
group of trucks for local security and antiaircraft protection. 

■ 23. Duties. — a. Section leader. — The section leader — 

CI) In accordance with instructions from the platoon leader 
or other higher commander, assigns position areas or ap- 
proximate locations for the guns, and prescribes the condi- 
tions governing the opening of Are. 

(2) Assigns positions for each squad and designates a truck 
assembly area for the section. 

(3) Exercises supervision over the firing and assigns pri- 
mary and secondary sectors of fire for each gun. 

(4) Checks the preparation of the firing and cover posi- 
tions and also the security and camouflage provisions at the 
gun and truck assembly area. 

(5) Assigns a mission and a position or position area to 
attached rifle units. 

(6) Insures that the squad leaders understand their mis- 
sions and the mission of the section (see par. 3). 

b. Chauffeur. — (1) The driver of the section leader's truck 
operates that vehicle in conformity with instructions of the 
section leader. Unless otherwise indicated he has super- 
vision over all vehicles of the section. 

(2) Carefully conceals or camouflages his vehicles and su- 
pervises the concealment and camouflage of the squad prime 
movers in the limber position. 

(3) Details one squad chauffeur to operate an automatic 
rifle against ground or air targets and the other squad chauf- 
feur to observe for hostile airplanes and ground patrols. He 
himself observes for signals or messages from the section 
leader and the gun positions. 

(4) Checks the fuel supply and operating condition of all 
vehicles in the limber position. 

■ 24. Fire Mission. — a. The section (in platoon) ordinarily 
receives its combat mission to cover a defined sector of fire. 
The platoon leader's order usually fixes the range limits lor 
opening fire. 

b. The distribution of fire missions to the squads depends 
upon the width of the assigned section sector. Wherever 



315165°— 41 2 



13 



24-27 



INFANTRY FIELD MANUAL 



practicable each squad covers the section sector in order to 
insure that the neutralization of one piece will not leave the 
entire sector without defense. 

c. A section may be detached to defend a designated area, 
to cover an avenue of hostile approach, or to support a rifle 
unit charged with a mission which requires the destruction 
of buildings, concrete emplacements, stone walls, and similar 
defensive works. 

■ 25. Route March. — a. The movement of the section (in 
platoon) is conducted in accordance with the provisions of 
FM 25-10. 

b. In the movement of the regiment, a section is frequently 
attached to a security element (advance guard, flank guard, 
etc.) or to a battalion, and executes the missions directed by 
the commander of the unit to which attached. During short 
halts or march bivouacs, antitank guns are uncoupled and 
placed in appropriate positions for immediate employment. 
Similarly in bivouac single sections are frequently posted to 
cover an approach or are attached to an outpost unit. 

■ 26. Regimental Approach March. — During the approach 
march the section may be employed as an echelon of an 
antitank platoon charged with the flank protection of the 
regiment. A section engaged in this mission ordinarily is 
reinforced by a rifle element. The mission of the section may 
be to cover an avenue of hostile approach for a prescribed 
period or until the regiment or a specified element thereof 
has passed. Depending on the situation, the section may 
execute this mission by improvising a road block, temporarily 
installing antitank mines, or by occupying a firing position 
or position, in readiness. 

■ 27, Reconnaissance and Occupation of Firing Position. — a. 
In preparation for combat, the platoon leader or other higher 
commander assigns the section a position or position in 
readiness to which the section leader moves his gun squads. 
At the same time or as soon thereafter as practicable, he is 
assigned a firing position area and a sector of Are. Accom- 
panied by the squad leaders, the section leader reconnoiters 
the designated position area, points out the fire sectors, and 
fixes the approximate gun emplacements. If there is danger 
of immediate attack the guns are brought forward and set 



14 



ANTITANK COMPANY, RIFLE REGIMENT 27-29 

up in temporary, hastily selected positions so that they can 
defend themselves and cover the area if hostile tanks appear 
before reconnaissance is complete. He locates the section 
observation post and the truck assembly area, and directs 
the movement of the squads into their positions and the prime 
movers into the truck assembly area. He supervises the prep- 
aration of the gun positions. He selects alternate and supple- 
mentary positions In accordance with the mission and the 
instructions of the platoon leader or other higher com- 
mander (see fig. 2) . 

b. The section is usually disposed with the squad Are posi- 
tions echeloned in depth so as to be capable of covering a deep 
field of fire toward a flank. 

c. Where a group of the rifle squad lias been attached to the 
section, the section leader assigns positions to the automatic 
rifle and the riflemen for the close protection of the antitank 
guns in accordance with the general methods prescribed in FM 
7-5. The position will often be located between the guns. 
An exposed flank may however call for the occupation of a 
flank position by part or all of the group. When available 
and required, a rifleman may be detailed as section observer 
and messenger. 

■ 28. Fire Direction and Control. — The section leader directs 
the Are of his guns by the assignment of fire sectors and by 
fixing the limiting range for opening Are. Exceptionally, the 
section leader may reserve the opening of fire on his order. 
He checks the fire-control measures of squad leaders, super- 
vises the ammunition supply, and directs the trucks to the 
proper ammunition distributing point for replenishment when 
required. 

■ 29. Displacement. — a. The section leader regulates dis- 
placements In support of an attacking unit in accordance with 
the mission or the instructions of the platoon leader. He 
executes a timely reconnaissance of new firing and truck 
assembly areas. He frequently displaces the section by squad 
echelons and in such a way as to maintain a distribution in 
depth for flank defense. This may require the rear squad to 
hold its position until the situation calls for the initiation of 
another bound of section displacement; especially will this 
be the case if the section is operating on an exposed flank. 



15 




16 



ANTITANK COMPANY, HIFLE REGIMENT 2&-31 

b. Displacement may be effected on order of the platoon 
leader or on the section leader's initiative. Before initiating a 
displacement, the latter is Informed as to the position area 
to be occupied and the sector to be covered in his new position. 
He reconnoiters the terrain of the displacement and pre- 
arranges the method of movement to the new positions with 
his squad leaders. He moves forward to the new position area, 
observes the location of and establishes liaison with advanced 
friendly troops, and selects an observation post and approxi- 
mate gun positions from which the assigned sector and the 
terrain toward the flanks can be observed and covered by 
fire. He selects a position where the guns can be uncoupled 
under cover and from which movement by hand to cover posi- 
tions in close proximity to the firing positions can be carried 
out. He directs the movement of the squads by prearranged 
signals or by messenger. Where the intervening terrain is 
visible or known, the squad or squads may be directed to pro- 
ceed forward to a specified place or along a specified route 
where further instructions as to the movement forward or 
occupation of positions will be given. 

c. Attached riflemen usually precede the section to new 
positions and are placed in position prior to the arrival of 
the guns. 

Section VI 
ANTITANK GUN PLATOON 

■ 30. Composition. — The antitank gun platoon comprises a 
command group, two antitank gun sections, and a rifle squad. 
Communications, reconnaissance, and pioneer elements are 
usually attached for the execution of detached or isolated 
missions. 

■ 31. Command Group. — a. Personnel, equipment, and trans- 
portation. — See appendix I. 

b. Duties. — (1) Platoon leader. — Commands the two sec- 
tions, the platoon transport (including section transport 
when assembled) , the command group, the rifle squad, and 
such reconnaissance, pioneer, and communications elements 
as may be attached. He may place the transport corporal in 
direct charge of all the vehicles in the truck assembly area 
and will usually do so in defensive situations, He insures that

31-32 



INFANTRY FIELD MANUAL 



the platoon mission is thoroughly understood within the 
platoon (see par. 3). 

(2) Platoon, sergeant, — Assists and replaces the platoon 
leader in the execution of his duties; supervises the operation 
of the command post and ammunition supply; brings up the 
rear of the platoon on the march and maintains contact with 
all elements of the platoon; performs the administrative 
duties of first sergeant when the platoon is detached. 

(3) Agent corporal. — Employed as liaison agent to the unit 
supported and keeps the platoon leader informed of the 
situation at all times. 

(4) Transport corporal. — (a) Conducts the platoon vehicles 
when assembled (ammunition and cargo trucks, command 
car) . 

(b) Directs the movement of the vehicles to the truck 
assembly area when guns are uncoupled. 

(c) Supervises the disposition of vehicles and the provisions 
for local security positions when platoon vehicles are assem- 
bled. 

(d) Designates a chauffeur to observe for signals and to 
receive messages from the platoon leader. 

(e) Checks on fuel requirements and mechanical condition 
of the platoon vehicles. 

(/) Performs duties of supply sergeant when the platoon is 
detached. 

(5) Instrument corporal. — Assists the platoon leader in 
conducting reconnaissance and in establishing an observation 
post. 

(6) One chauffeur. — Operates the command car as directed 
by the platoon leader. 

(7) Two messenger s.~ Trained also as observers and to 
operate the sound-powered telephones and the portable voice 
radio sets. One usually accompanies the platoon leader, the 
other assists the instrument corporal at the observation post. 

■ 32. Distribution of Personnel for Movement. — The pla- 
toon leader, the agent corporal (when not detached), the 
instrument corporal, one messenger (with voice radio set), 
and the chauffeur are usually transported in the command 
car. The platoon sergeant, the transport corporal, and the 
remaining messenger of platoon headquarters ride on other 
platoon vehicles as directed by the platoon leader.

ANTITANK COMPANY, RIFLE REGIMENT 



33 



■ 33. Regimental Approach March. — a. The platoon usually 
operates as a unit under the immediate direction of the pla- 
toon leader. It may be assigned to a specific mission of flank 
protection of the regiment or to support a designated rifle 
echelon or unit. 

b. In assigning a mission of flank protection, the regimental 
development order usually indicates the approaches which 
must be defended so far as this can be foreseen. The initial 
order or subsequent instructions of the company commander 
Indicate the period of release of antitank defense of each 
designated approach or area. The order may also attach rifle, 
reconnaissance, and communication elements to the platoon. 

c. Upon receipt of instructions assigning the platoon a 
flank protection mission, the platoon leader usually prescribes 
a place where the platoon will remain under cover while he 
conducts a reconnaissance accompanied by the rifle squad 
and appropriate personnel. Movement is conducted in ac- 
cordance with the fundamentals of security and reconnais- 
sance. Based on his reconnaissance, the platoon leader se- 
lects a single position or several alternate positions on which 
the antitank defense will be made. In the latter case, he 
locates a position in readiness for the platoon and routes 
leading to the several selected firing positions. He establishes 
observation posts from which the hostile approach can be 
discovered in time to permit the occupation of firing posi- 
tions for antitank action. 

d. The second in command conducts the platoon to the 
designated place of cover, making such provisions for security 
as the situation and the means available permit. 

e. After the reconnaissance the platoon leader rejoins his 
platoon and conducts it as promptly as possible to the un- 
coupling position or position in readiness. He establishes 
some means of communication from his command post 
to the observation post(s). He assigns position areas and 
sectors of fire to the sections and takes the necessary meas- 
ures for the close defense of the platoon. When sufficient 
means are available security groups are established for the 
flank protection of the position. He gives the transport 
corporal the necessary instructions for the dispositions of 
personnel and vehicles in the truck assembly area. He com- 
municates his dispositions to the company commander at the 
earliest practicable moment. 



19 



33-34 



INFANTRY FIELD MANUAL 



/. As the regiment continues its advance the platoon leader 
Initiates reconnaissance for prospective position areas. 
Where practicable one section may be withheld from occupa- 
tion of a firing position and held in readiness for movement 
to the next area to be occupied. 

■ 34. Support of Attacking Echelon. — a. The platoon ordi- 
narily receives its orders in the regimental assembly area. 
It protects the occupation of the assembly position and the 
advance therefrom. Where a platoon is assigned the mission 
of protecting a rifle echelon or unit, it usually follows the ad- 
vance of the echelon or unit in a state of readiness for the 
action required by the situation. Movement is made by 
bounds to successive cover positions, which may be occupied 
with pieces limbered, and from which firing positions can be 
readily occupied. Position areas and sectors of fire are 
assigned to sections. Provision for observation and local 
security are continuous. Plank protection may require an 
echeloned advance from successive firing positions. Sections 
usually displace by squad echelons. The platoon follows the 
unit to be protected as closely as available cover will permit. 
It also protects the troops from being rolled up by tank 
attack from the flank. Echeloned advance is frequently 
necessary. 

b. Based on the regimental order and the instructions of 
the company commander, the platoon leader Issues his orders 
for the protection of the troops in the assembly area and in 
the attack. He assigns initial position areas and sectors of 
Are to his sections and prescribes the method of displacement. 
The terrain and situation may permit him to assign succes- 
sive position areas to his sections to protect the advancing 
rifle units or echelon. Difficult terrain or a vague situation 
may require that he assign a zone of action, to each section, 
in which case the section leaders must execute vigorous and 
continuous reconnaissance of position areas to insure that 
the guns execute timely and effective displacements. The 
platoon leader distributes the rifle squad to the sections or 
assigns It definite security missions. 

c. The situation of the attacking echelon, the terrain of 
the displacement, and the intensity of the hostile fire thereon 
influence the initiation of a displacement. As a general rule 
the attacking echelon should have gained a position in ad- 
vance of a terrain feature which can be utilized as cover for 



20 



ANTITANK COMPANY, RIFLE REGIMENT 34-39 

the antitank guns. Where the terrain of the displacement is 
exposed to intense flat trajectory fire It may be necessary to 
await the capture of a terrain feature masking the movement. 
Level terrain which does not prevent motor movement 
at high speed may permit displacement to a covered position 
in spite of intense hostile fire on the zone of displacement. 

d. With the close approach of the attacking echelon to 
assaulting distance from its objective, the platoon leader 
seeks to concentrate his guns as far forward as the situation 
and the terrain permit. On the capture of the objective he 
disposes the guns so as best to protect the assaulting troops 
from armored counterattack. This may call for movement 
of the guns into a position affording protection against flank 
attack. 

■ 35. Defense. — a. The combat mission of a platoon in the 
regimental defense may be the defense of a designated sector, 
covering an area or avenue of approach for hostile tank 
attack, or the protection of a designated unit or echelon. 

b. The platoon leader assigns a sector of Are, distributes his 
sections, assigns position areas, and directs the fire of his 
sections as prescribed in paragraph 34b.

22 



ANTITANK COMPANY, RIFLE REGIMENT 41-44 

■ 41. Transportation. — a. The command group transporta- 
tion comprises 1 command car, 1 radio truck, 1 truck, weapons 
carrier, and 4 motorcycles. * 

b. The following vehicles are Included in the antitank sec- 
tion of the service company of the infantry regiment for the 
transportation of the antitank company kitchen, baggage, 
and ammunition: 1 trailer (cargo), 1 truck (ammunition), 
and 1 truck (kitchen and baggage) . 

■ 42. Signal Communication. — The communication means 
of the company include radio, visual signaling, sound-pow- 
ered telephones, motorcycle messengers, and foot messengers. 
In stabilized situations and frequently in defense, wire com- 
munication is established by the regimental communications 
platoon between antitank units and the nearest unit having 
communication lines to higher and adjacent units. 

B 43. Mission. — The missions of the antitank company in- 
clude the protection of a rifle unit, the defense of an area, 
or the covering of an avenue of approach or several apn 
proaches available to hostile mechanized units. 

■ 44. Regimental Route Makch.— a. The distribution of the 
company for the protection of the column varies according 
to the terrain, the enemy situation, and the distribution of 
friendly troops. In an interior regiment the most dangerous 
direction of hostile armored attack during an advance is from 
the front, and the bulk of the company marches well for- 
ward in the column. .When the troops to be protected are 
the leading elements it may be necessary to attach one or 
more antitank platoons to the leading advance guard or cov- 
ering units. In an advance with an unsupported flank, a dis- 
tribution of antitank elements between the leading battalion, 
the flank guard (where detached from the regiment) , and the 
remainder of the regiment is usually indicated. Antitank 
units with the main body are carefully coordinated with 
advance and flank detachments with a view to providing 
depth to the defense. 

b. The company commander initiates early reconnaissance 
of areas to be occupied as bivouacs or during long halts with 
a view to the most effective distribution of the company for 
the antitank defense of the troops. Dispositions are coor- 
dinated with outposts and local security detachments. As 



23 



44-45 



INFANTRY FIELD MANUAL 



far as practicable troops are bivouacked in areas impracticable 
or difficult for tank movement or protected by a natural anti- 
tank obstacle. 

c. Dispositions for antitank defense are taken, both on the 
march and in shelter, by all regiments in leading infantry 
divisions regardless of the presence of covering forces in their 
front. 

d. The company command group habitually marches with 
the regimental command, group. 

■ 45. Regimental Approach March. — a. On development of the 
regiment from route column, the command group usually 
functions in the vicinity of the regimental command group. 
The development order of the regimental commander assigns 
protective missions to the antitank company. These may 
Include — 

(1) Flank protection of the regiment against armored at- 
tack from specified directions or areas. The order may desig- 
nate the successive areas or avenues of approach to be de- 
fended against tank approach. 

(2) Protection of the advance of a battalion or echelon of 
the regiment. (The regimental order may attach an antitank 
platoon to a rifle battalion.) 

b. The company commander distributes the platoons for ■, 
the execution of assigned missions. He reinforces them where 
necessary with additional means in reconnaissance, communi- 
cation, and rifle elements placed at his disposition by the 
regimental commander. 

c. Exclusive of forces required by the situation for flank 
protection, the distribution of the antitank company during 
an uncovered approach of the regiment is frequently as 
follows : 

(1) One platoon attached to or supporting each leading 
battalion. 

(2) Remainder of the company to provide protection for 
the second echelon of the regiment. 

d. Missions assigned to platoons include — 

(1) For flank defense (where necessary) , covering successive 
areas or routes of approach against hostile armored -forces. 

(2) Protection of a designated rifle battalion or echelon. 
(The initial position of the platoon and the method of move- 
ment are prescribed by the company commander.) 



24 



ANTITANK COMPANV, RIFLE REGIMENT 45--47 

e. The company commander maintains contact with his 
platoons by voice radio and motor vehicle. The reconnais- 
sance officer with one or more messengers accompanies the 
regimental reconnaissance detachments. He reconnoiters the 
terrain especially to locate antitank obstacles; routes favor- 
able to hostile tank approach, stream crossings, obstacles to 
motor movement, and necessary detours. He reconnoiters 
the approach objectives designated by the regimental com- 
mander with a view to the possible antitank defense of the 
regimental assembly areas and the location of positions in 
support of the regimental attack. He promptly transmits im- 
portant items of information to the company commander by 
messenger. 

■ 46. Regimental Assembly for Action. — a. Dispositions of 
the antitank company for the protection of a regimental 
assembly for action are anticipated by early reconnaissance 
of assembly areas. Redistribution of antitank elements for 
this purpose and for the support of an attack is usually 
necessary. 

b. The company commander assigns position areas to the 
platoons and locates an observation post affording a field of 
view over the foreground of the area and toward the flanks. 
He assigns a position to the company command group vehicles 
as near the command post as requirements for cover and 
proper distribution will permit. 

■ 47. Attack. — a. The regimental attack order assigns sup- 
porting and flank protection missions to the antitank com- 
pany as required by the situation. Exceptionally, It may 
direct the attachment of platoons to rifle battalions. This 
may be the case where the attack Is made on a particularly 
wide frontage or where visibility is restricted by terrain 
features. 

b. Supporting missions may require platoons to protect 
designated battalions. More frequently regimental orders 
specify the number of platoons to be assigned to provide 
antitank protection for the attacking echelon as a whole, and 
leave the assignment of platoon missions to the company 
commander. 

c. Where the regiment attacks with an exposed flank or 
where for any other reason possible armored counterattack 



25 



47-48 



INFANTRY FIELD MANUAL 



may be anticipated, a portion of the company is held in 
reserve or disposed in depth. The position and mission of 
the antitank elements so employed are coordinated with the 
regimental reserve. 

d. The mission initially assigned to a platoon protecting 
the attacking echelon will usually be to cover a defined sector 
of fire, and as the troops advance to displace forward with a 
view to providing continuous protection. Sectors of fire may 
be redefined on each displacement, or zones of action may be 
assigned each platoon. Where terrain conditions along the 
entire front are substantially the same, a platoon may be 
assigned to the protection of each battalion in the attacking 
echelon. 

e. A platoon in reserve may be assigned to an initial posi- 
tion area with the mission of covering a defined sector of Are 
or blocking a specified approach, or It may be assigned a 
position in readiness with the mission of blocking several 
approaches to hostile armored forces. The company com- 
mander restates the mission as required by the progress of 
the attack. 

■ 48. Displacement.— a. The company commander prepares 
for displacement by suitable instructions pertaining to the 
new position areas of the platoons on initial displacement. 

b. The reconnaissance officer, accompanied by the recon- 
naissance and signal sergeant and one or more messengers, 
closely follows the attacking echelon. He reconnoiters the 
position areas indicated by the company commander and the 
foreground with special reference to tank obstacles and ap- 
proaches. Where practicable he recommends platoon posi- 
tion areas and sectors of fire to the company commander. 
In making these recommendations, consideration is given 
to the existing or planned dispositions of battalion antitank 
weapons so as to insure coordination of effort. 

c. The company commander may regulate the displace- 
ment of platoons by the assignment of zones of advance to 
the platoons or by the indication of platoon position areas 
based on the reconnaissance of the company reconnaissance 
officer. He may delegate the initiation of the displacement in 
accordance with general instructions to platoon leaders or 
reserve execution of the movement on his own order. The 
displacement of supporting platoons must be initiated as soon 



26 



ANTITANK COMPANY, RIFLE REGIMENT 48-50 

as the attacking rifle echelon clears terrain masking the 
fire of the antitank guns. Where the attacking echelon oc- 
cupies a position on or near a crest, the guns may move into 
the lines of the leading rifle units or occupy cover in readiness 
for such movement. 

■ 49. Pursuit. — Platoons are usually attached to rifle battal- 
ions with a view to defending the pursuit force against hostile 
armored forces which may attempt to block or retard the 
pursuit. Full advantage should be taken of opportunities to 
engage retreating enemy armored vehicles or motorized units 
in march column or when traversing defiles. 

■ 50. Regimental Defense. — o. The principal mission of the 
antitank company is the Immediate protection of the regi- 
mental area. The guns are disposed to cover avenues of tank 
approach leading into the defensive area of the regiment. 

b. The method of defense of the main line of resistance is 
greatly influenced by the time available for the preparation 
of the position. In the hasty organization of a defense, it is 
advantageous for some antitank guns to occupy a crest posi- 
tion within close range of the main line of resistance that 
affords cover for the guns and that facilitates covered move- 
ment to alternate positions. Whenever possible gun positions 
are selected in terrain which is unfavorable for tank opera- 
tion but from which antitank guns may deliver effective 
flanking fire against favorable avenues of approach. Guns 
are located in depth and in concealed firing positions along 
the flanks and irregularly across the approaches so that hos- 
tile tanks are compelled to advance against a continuous vol- 
ume of effective frontal, oblique, and enfilade fire. The con- 
figuration of the ground, available means, and the enemy 
situation will influence the depth of antitank dispositions. 
Antitank means must be flexibly disposed to permit timely 
employment either to the front or to a flank. Antitank units 
of reserve regiments should be assigned definite missions 
which may include the reinforcement of the front line regi- 
ments and the protection of avenues of tank approach lead- 
ing Into the regimental area from the flanks or rear. 

e. Outpost guns occupy crest positions covering avenues or 
areas feasible for tank employment with a view to disrupting, 
canalizing, and retarding the hostile tanks in their advance to 
the main position. 



27 



50-53 



INFANTRY FIELD MANUAL 



d. A platoon protecting the regimental reserve conforms to 
the plan for the employment of the reserve. Its positions and 
plan of action are coordinated with natural and artificial 
obstacles so as to protect the departure positions of the re- 
serve in counterattack against hostile foot troops follow- 
ing attacking tanks. It locates and prepares positions In sup- 
port of the plan for the tentative flank lines of resistance to 
be occupied by the regimental reserve In case the enemy pene- 
trates an adjacent sector. A platoon In support of the regi- 
mental reserve usually occupies a position in readiness and 
establishes observation posts to cover the approaches to the 
several alternate firing positions selected. 

■ 51. Withdrawal. — Antitank units are usually attached to 
the covering force. Where necessary an element is held under 
regimental control for flank protection and detached mis- 
sions. Positions are occupied with a view to facilitating the 
withdrawal of the regiment by defending against hostile 
armored elements of the pursuing forces. 

Section VIII 

AMMUNITION 

■ 52. General. — Eighty rounds of ammunition are considered 
sufficient for one battle mission and are therefore carried on 
the squad prime mover. Two missions (160 rounds) are 
transported in the section leader's truck. When the squad 
goes into action as part of the section, the ammunition trans- 
ported on the section leader's truck is carried to the gun 
position for initial use. The ammunition transported on the 
prime mover and in other company transport is available as 
reserve. 

■ 53. Replenishment. — The platoon leader is responsible that 
the ammunition supply is promptly replenished and that 
sufficient ammunition is available at the gun positions to in- 
sure the successful completion of prospective fire missions. 
The squad leader reports ammunition requirements to the 
section leader, who transmits the information promptly to 
the platoon leader. When the squad requires immediate re- 
plenishment, the squad and section leaders obtain ammuni- 
tion from the section vehicle.
