COMMANDER'S ATTENTION
Soldier's Manuals are designed to tell soldiers what tasks they must be
proficient in to be MOS qualified. If soldiers follow the road map these
manuals provide, they should progress readily to positions of responsibility
commensurate with their aptitude and motivation .
Initial distribution of Soldier's Manuals will be made to the unit level, based
upon assigned strength in the particular MOS and Skill Level . In the event
additional manuals are needed by the unit for MOS study, libraries, or other
training needs, requests for publications may be sent directly to the US
Army Publications Center, 2800 Eastern Boulevard , Baltimore, MD 21220 .
When soldiers are issued Soldier's Manuals by their units , they are
responsible for retaining and maintaining them . If they transfer, they must
return the manuals to their units.
This Soldier's Manual was prepared by the US Army Armor School , Fort
Knox, Kentucky.

CHAPTER 1
INTRODUCTION
Recent battle experience has shown that long range , high velocity tank
cannon and long range antiarmor missile systems will dominate future
battlefields. These weapons are so lethal that:
WHAT CAN BE SEEN CAN BE HIT.
WHAT CAN BE HIT CAN BE KILLED .
To defeat the Threat, US forces must be able to find the enemy first,
outmaneuver him , and outshoot him to achieve a kill ratio of five to one . The tank
driver plays a key role within the US forces.
As a tank driver, you serve as a member in a unit that conducts armor
operations. To accomplish these missions , you and your unit must be well
trained. This Soldier's Manual is designed to help you train . It tells you what
tasks you are expected to perform , the conditions under which you are expected to
perform , and the standards you are expected to meet in your performance. If you
use this manual , you and your unit are on the way to becoming trained .
Remember, only the well- trained soldier and unit are successful on the battlefield .
When you are promoted , you should obtain the next higher skill level manual
by mailing the order blank enclosed in the back of this manual .

HOW TO GET READY FOR THE SKILL
QUALIFICATION TEST ( SQT)
Being able to perform the skill level of the next higher grade is part of the
requirement for promotion , and award of thenext skill level is determined by how
high your SQT score is . Therefore, it is important that you be ready to take the
SQT . You get ready for the SQT by training . This Soldier's Manualis designed to
help you train yourself . The task summaries in this manual tell you the tasks and
standards for the skill levels of your MOS . Remember , you will be tested on some
of the tasks and must meet these standards when you take the SQT. In addition to
the Soldier's Manual there are other learning materials you can use on your
own : training extension course (TEC ) lessons , supplemental texts and TV tapes ,
subcourses , correspondence courses , field manuals ( FMs ) , and technical manuals
( TMs ) . See your squad leader or first sergeant for a catalog . The Armor School
publishes catalogs which list all the Army training lessons and materials
available for your use .
If no one can help you find the training items , write:
Director of Training
US Army Armor School
ATTN : Field Support Branch (AWTS )
Fort Knox , Kentucky 40121
Your skill level is determined by how well you do on the SQT. At least every 2
years ( 4 years for Reserve Component personnel ) you must take an SQT for the
skill level just above your present one . The test will be made up of tasks from the
Soldier's Manual . If you don't pass the SQT , you are not qualified at your present
level and must take the SQT again within a year . If you pass the test (by
achieving a minimum score announced each year) , you " verify ” (keep your
present skill level . If you score high enough , you are eligible for the next skill
level .
For example , if you are a soldier in MOS 19G10 , you must take SQT2 to reach
SL2. This test has both written and performance parts.
SQT 2 requires you to show that you can do the tasks at SLl and SL2 . These
tasks and their standards are described in the task summaries in this manual .
Remember , you can be tested on any of these tasks , so learn them .
If you score below the minimum level on SQT2 , you are not qualified at SL1
and must retake the SQT within the next year . If you score above the minimum
level , you verify your SL1. If you score above a higher passing level ( announced
each year) , you are eligible for SL2. You can then begin training for SL3.
1-10 FM 17-19F
COMPONENTS OF THE SQT
Hands - On Component ( HOC )
Included in all SQTS .
Requires the soldier to perform actual tasks in a job - like test
situation .
Given during the test period at a time determined by the test control
officer (TCO ).
Performance Certification Component ( PCC )
Included in all SQTs.
Requires the commander / supervisor to evaluate the soldier's
performance of tasks on the job .
Given any time during the test period .
Skill Component ( SC )
Uses a test booklet and answer sheet which is filled out by the
soldier .
Given during the test period at a time determined by the TCO .
Test critical tasks which cannot be readily tested in the hands - on or
performance -certification components .
Sixty to 90 days before the SOT is given , you will receive an SOT notice . It will
inform you of the tasks to be tested in each part of the SOT and how the tasks will be
tested . There are three different ways to test a task . First , you may be asked to answer
a written question about how a task is performed ( skill component ) . You will pick the
correct answer from a list of answers and mark the correct answer on a machine
scorable answer sheet . Second , you may be asked to actually do the task . For example ,
you may be given a coax or M60 machinegun ( depending on your MOS ) and be asked
to prepare it for firing . This is called a hands - on component . Third , your unit
commander n.ay observe your performance of a task and report your ability to perform
it (performance certification ) as a part of your SQT score . Your performance on the
SQT will be reported to you on an Individual Soldier's Report ( ISR ) within 30 days from
the day you complete the last component of the SQT . The report will be sent to the test
control officer for dispatch to you and your commander . An example of an ISR is on the
next page .

ever apply a tourniquet are when an arm or leg has been
cut off or when there very heavy bleeding which
cannot be stopped by the pressure methods described
above .

the wound and the heart . The object is to stop bleeding and
save as much of the arm or leg as possible .
(1 ) If an arm or leg has been cut off below the elbow or
below the knee , place the tourniquet above the elbow
joint or knee joint to get good bleeding control and to
keep the tourniquet from slipping off .
(2) If the arm or leg has been cut off above the elbow or
the knee , place the tourniquet as close as you can to
the wound and still be able to get a firm hold on the
arm or leg so that the tourniquet will not slip off .
CAUTION : If only part of a hand or foot has been cut
off , you should stop the bleeding using the
pressure methods .
(3) If a wound is bleeding very heavily and you have not
been able to stop the bleeding using the pressure
methods , place the tourniquet as close as you can to the
edge of the wound .

ACQUIRE TARGETS
CONDITIONS
In a field environment with or without optics , given friendly and
enemy targets with or without camouflage at various ranges and
positions surrounding your location .
STANDARDS
Detect and locate each target within your sector and identify each as
friendly or enemy within 10 seconds during daylight and 15 seconds at
night .
PERFORMANCE MEASURES
1. Detect and locate friendly and enemy targets .
a. Continuously scan your assigned area of responsibility ( fig
1 ) . Without optics , make a quick overall search for obvious
targets using all your senses to detect tell- tale target
signatures . Concentrate on areas where targets are most
likely to be employed .
(1 ) Soldier signatures foxholes , trash , torn out vegeta
tion used for camouflage , fires , and odors such as
cooking food , burning tobacco , or aftershave lotion .
(2 ) Track vehicle signatures OO tank tracks on the ground ,
track and engine noise , dust clouds , fuel smoke and
odor , white puff of smoke followed by
followed by a loud sharp
report , and a bright white flash at night . Look for
these signatures in open areas and rolling terrain .
(3) Antitank signatures OO swishing sound of missile launch ,
long thin wires from previously fired ATGMS , tracers of
slow flying ATGMs , sharp crack of antitank guns , and
dismo unted gunner up to 80m away from the launching
rail . Look for antitank employment in open areas where
tanks are likely to be used .
FM 17-19F 2-129
TASK SUMMARY 171-121-1008 ( cont )
PERFORMANCE MEASURES ( cont )
(4) Artillery signatures loud , dull report ; grayish white
cloud of smoke ; bright orange flash ; black smoke from
airbursts ; and a rushing noise heard several seconds
before impact of the round .
(5) Aircraft signatures -- aircraft noise , glare of sun from
aircraft canopies and rotor blades , vapor trails from
aircraft or fired missiles , and dust and movement of
foliage from hovering helicopters . Look for these
signatures where terrain masks such as ridges or forests
are available for aircraft to hide behind .
(6 ) Obstacle and mine signatures loose or disturbed dirt
in a regular pattern . Look for positions between
uncrossable terrain features and areas covered by enemy
fire ( usually infantry with antitank weapons ) .
b.
With the aid of optics , make a more detailed search of your
area of responsibility using the 50 -meter method to locate
specific targets .
(1 ) Search a strip 50 meters deep from right to left .
(2 ) Search another strip from left to right farther out ,
overlapping the first strip .
(3 ) Continue this method until the entire sector is covered .
(4 ) When a suspicious spot is detected , stop and search it
thoroughly .
c. To locate suspected enemy air targets , start by searching
from far to near .
d. Use optics whenever suspected targets are too far away to
identify with the naked eye or when buttoned up in a vehicle .
Binocular efficiency can be improved by using only one
eyepiece or cupping the eyepiece with your hands to prevent
stray light from entering your eyes .

TASK SUMMARY 171-121-1008 ( cont )
PERFORMANCE MEASURES ( cont )
e. Detect and locate targets at night using the same techniques
described above ; however , do not look directly at a suspected
target but a few degrees off to the side since the sides of
your eyes are more sensitive to dim light and movement . When
scanning with this off - center vision , move your eyes in
short , abrupt , irregular movements . When using optics at
night , use a dim reticle or none at all to improve night
observation .
2. Identify the target as friendly or enemy ( see Task Summaries 071
331-0814 , Identify Friendly and Threat Vehicles , and 171-091-1015 ,
Identify Friendly and Threat Aircraft ) .
3. Identify the degree of danger presented by each target and engage
the most dangerous first .
a. Most dangerous targets are those that see you , have the capa
bility of killing you , and appear to be preparing to engage
you .
b. Dangerous targets are those that can kill you , but apparently
do not see you .
C. Least dangerous targets are those that do not have the
immediate capability of killing you , but can report your
position to someone who is capable of killing you .
4. Report the acquisition of a target or targets to your supervisor
or vehicle commander .

COMMUNICATE USING VISUAL SIGNALLING TECHNIQUES
CONDITIONS
Given a combat or field training situation with necessary flags or
flashlights , and you are moving dismounted or mounted . Radio
communications may not be available and radio silence may or may not
be imposed .
STANDARDS
Demonstrate the correct procedure for each signal in the performance
measures below .
PERFORMANCE MEASURES
1. Visual communication is a means available to all units . Visual
signals are transmitted by flags , lights , pyrotechnics , panels ,
and arm - and - hand prearranged messages rapidly over short distances
as well as for recognition and identification of friendly forces .
2. Visual signals also facilitate ease in controlling the action ( s )
or movement ( s ) of the follower and conversely visual signals can
influence the action ( s ) or movement ( s ) of the leader .
3. It is important that you familiarize yourself with all the visual
signals used on the battlefield . However , it is more important
that you know those signals which can assist you in performing
your specific job effectively in event alternate means of
communication are not available .
4. Signals for combat formations and battle drill .
a.
These signals may be used , as appropriate , by either mounted
or dismounted troops . They give the soldier a means of
communication between himself and other persons or units .
They must be practiced until their use becomes second nature .

a• Take the tow hook ( or tow shackles ) off the disabled vehicle .
b. Chock or block the tracks of the disabled vehicle if the
final drives ( or drive shaft ) of the disabled vehicle are to
be removed . This will hold the vehicle in position since
there are no brakes or steering control once the final drives
( or drive shaft ) are removed . ( If another vehicle is present
with a tow bar , hook up the tow bar and skip the chock and
block steps . )
c. Disconnect the final drives ( or drive shaft ) under
supervision of the track recovery vehicle crew or
organizational maintenance personnel .

SELECT TEMPORARY BATTLEFIELD POSITIONS
CONDITIONS
During daylight or darkness ; at an overwatch postion ; after initial
movement into tentative defensive positions ; at a halt during
movement ; or upon receiving direct fire .
STANDARDS
1. Select and occupy a firing position which allows observation ,
fields of fire , and provides ( in order of priority ) :
a. Cover and concealment , or
b. Cover only , or
c. Concealment only .
2. Remain as low as possible ( prone where possible ) and look ( aim )
around rather than over objects .
PERFORMANCE MEASURES
Select temporary firing or observation positions which take advantage
of available cover and concealment ( fig 1 ) .
1. Observe and fire around the side of an object . This conceals most
of your head and body .
2. Stay low to observe and fire whenever possible . You can aim
better and take advantage of concealing vegetation to present the
smallest possible target to enemy observation and fires .
3. Select a good background before observing . A good background does
not silhouette the individual .
4. Follow your leader's directions after your initial selection of
temporary battlefield position ; he might reposition you to gain
better team coverage of the area .

cannot hold a good sight picture of your vehicle for more than 10
continuous seconds .
PERFORMANCE MEASURES
1. Select a route .
a. Select a route that is as level as possible to keep the main
gun level .
b. Take the shortest route to the objective as possible , but
allow for maximum cover and concealment . Make every effort
to prevent exposing the sides or rear of your vehicle to
suspected enemy gun emplacements or ATGM fire .
c. Drive the tank So that the gunner can always orient the
turret to allow for full fields of fire for the main gun .
d. Where possible , select terrain that makes it difficult for
the enemy to detect your tracks .
e. Drive around areas where the vehicle could become mired .
2. Use cover and concealment along the route .

BATTLESIGHT ZERO AN M16A1 RIFLE
CONDITIONS
On a 25 -meter firing range , given an M16A1 rifle equipped with either
the standard M16A1 sights or the low light level sight system ( LLLSS ) ,
18 rounds of 5.56 - mm ammunition , battlesight zero target , sandbag for
support , and a rifle shot group analysis card : semi - automatic fire
with M16A1 and M14 rifles ( GTA 21-1-4 , Mar 74 ) .
STANDARDS
Place the center of a three - round shot group at the X which is 2.4
centimeters below the Canadian bull's - eye , and have the shot group
touch or fall within a 5.2 - centimeter - diameter circle centered on the
X.
PERFORMANCE MEASURES
1. Sights . The M16A1 rifle has two adjustable sights . Elevation
adjustments are made on the front sight , and windage adjustments
are made on the rear sight . The rifle comes equipped with either
the standard sight system or LLLSS .
a. The standard sight system .
( 1 ) The rear sight has two parts :
( a) An aperture marked " L " for ranges beyond 300 meters
and an unmarked aperture for ranges from 0 to 300
meters .
( b) A windage drum for windage adjustments .

(1 ) The rear sight in this system also has two parts :
(a) A 2 - mm aperture marked L which is used for zero and
ranges to 460 meters under normal conditions . The
other ( 7 - mm ) aperture is larger than the standard
sight and is used for night and limited visibility
firing .
( b) A windage drum for windage adjustments ( same as the
standard system ) .
(2) The front sight has only four notches ( clicks ) of
elevation ( the standard system has five ) . This permits
the firer to adjust the sight so he can see the luminous
part through the rear sight .
CAUTION : The front sight post contains a small glass
vial of radioactive promethium 147 . Take care
not to bump , abuse , tamper with , or alter the
post in any manner . Do not blacken or soot up
the front sight .

arrow and letter R. Το move to the left , move the drum
counterclockwise . Each graduation ( notch ) moves the point of
impact of bullet as indicated in chart .
b. Front sight . To adjust elevation , depress the detent , rotate
the post . To raise the strike of bullet , rotate the post in
the direction of the arrow marked UP . Reverse the direction
of rotation to lower the strike of bullet . Each graduation

3. Battlesight zeroing .
a. Sight picture . In aiming , the firer is concerned with
correctly pointing his rifle SO the bullet will hit the
target when he fires . To do this , he must have the rear
sight , the front sight post , and the target or aiming point
in their proper relationship --known as sight picture . A
correct sight picture is obtained when the sights are
perfectly aligned and the aiming point ( target ) is in the
correct relationship to the front sight post ( fig 2B ) . Sight
picture includes two basic elements : sight alignment and
placement of the aiming point .
b. Sight alignment . To obtain the correct sight alignment , the
sights are aligned as shown in figure 2A . Notice that the
top center of the front sight post is exactly in the center
of the rear sight aperture . If an imaginary horizontal line
were drawn through the center of the rear sight aperture , the
top of the front sight post would touch this line . If an
imaginary vertical line were drawn through the center of the
rear sight aperture , the line would bisect the front sight
post . The firer makes sure he has perfect sight alignment by
concentrating his attention and focusing his eye on the front
sight post through the ind istinct
indistinc t or fuzzy appearing rear
sight aperture . By doing this , any errors in sight alignment
can be easily detected and corrected .
c. Placement of the aiming point . The aiming point ( target on
which firer has aligned his rifle sights )
the is correctly
placed when it is centered on and appears to touch the top of
the front sight post ( fig 2C ) . If the aiming point is
correctly positioned , an imaginary vertical line drawn
through the center of the front sight post will appear to
split the front sight post in half .
Battlesight zero target . The standard 25 -meter target ( fig
1 ) is used when determining the battlesight zero for the
M16A1 rifle . Vertical and horizontal lines are printed on
the target , forming 1.4 - centimeter squares . One click of
elevation or windage will move the strike of the bullet 0.7
centimeters at a range of 25 meters . Thus , on the 25 -meter
target , two clicks of elevation or windage will move the
strike of the bullet one square .

Note . The LLLSS has only four clicks of elevation , but it is

e. Determining the battlesight zero . The 250 -meter battlesight
zero is determined by firing a series of three - round shot
groups at the 25 -meter target . The firer aims at the
distinctive aiming point at the bottom center of the black
rectangle ( base of the white cutaway portion ) and adjusts his
sights until the center of this acceptable shot group is
located 5.2 centimeters directly below the aiming point
( fig 3 ) on or around the x .

Note . To battlesight zero , adjust your sights so you can hit
an aiming point at 250 meters . Zeroing can also be
done on
on a 25 - meter range by adjusting the sights 30
that the bullet will strike 2.4 centimeters below the
point of aim . If your M16A1 has an LLLSS and you
cannot see the vial after zeroing , turn front sight
post one click down for use during periods of limited
visibility .

At night and in limited visibility , use unmarked ( 7 - mm )

sight post within the 7 - mm aperture on target and fire .
Under certain light conditions , the front sight post can
be seen , but you can't determine whether you are looking
through , above , or to the side of rear sight aperture .
Practice positioning the stock against your shoulder and
looking through rear aperture .

3. If your rifle stops firing with a live round in the chamber
of a hot barrel , remove the round fast . However , during
training , if you cannot remove it within 10 seconds , wait 15
minutes with the rifle pointing in a safe direction , This
way you won't get hurt by a possible ammo cook- off , which
.
could happen 10 seconds after contact with a hot chamber .
4. Use only authorized ammo that is manufactured to US
specifications .
5. If your bolt fails to unlock and you try to free it by
banging the butt stock on the ground , keep yourself clear of
the muzzle .
6. If there's water in the barrel , don't fire the rifle . It
could explode .
7. If a noticeable difference in sound or recoil is experienced ,
STOP FIRING . Either condition could indicate an incomplete
propellant burn and a bullet still in the bore . Retract bolt
slowly and remove fired cartridge case . Clear weapon and
check for unburned powder grains in the receiver or bore and
for a bullet in the bore . Remove unburned propellant or
bullet from bore before resuming firing , oror barrel

IDENTIFY FRIENDLY AND THREAT ( OPFOR ) VEHICLES
CONDITIONS
In a field environment with friendly and Threat ( opposing force / OPFOR )
vehicles in sight .
STANDARDS
Within 8 seconds , identify each vehicle sighted as friendly or Threat .
PERFORMANCE MEASURES
1 . Tank characteristics .
a. Identification . Tank identification is designed around four
areas common to all tanks :
( 1 ) Track and suspension system .
(2) Turret .
(3) Main gun .
(4) Cupola .
b. Track and suspension system . Many tanks can be recognized by
their track and suspension systems . However , recognition by
this feature alone is often difficult as the tracks will
often be obscured by grass or other objects . To identify the
track and suspension system , check to see if it has support
or return rollers . Except for the T- 10 , M- 1970 , and T - 72
tanks , most Warsaw Pact vehicles do not have these rollers .
Note . When using this method to help identify tanks , keep in
mind that the M551 Sheridan in the US Army also has no
return rollers .

2. Tanks . Threat main battle tanks are smaller than the US main
battle tank . They have a cruising range of about 300 miles
without auxiliary fuel and can attain speeds of about 30 mph .
Threat tank fire control is relatively simple compared to that of
US tanks . Currently , they mount no rangefinder similar to those
on US tanks . Most Threat main battle tanks are equipped with
active infrared ( IR ) night viewing devices , and have a superior
underwater snorkeling capability .

PERFORMANCE MEASURES ( cont )
The T- 10 heavy tank is rarely seen in Threat forward areas . This tank
stays in the rear and is used in counterattacks or with tank killer
units . It is equipped with infrared sights or devices for all crew
members , and has seven pairs of roadwheels . Its primary weapon is a
kinetic energy armor- piercing cap and
122 - mm stabilized gun firing kinetic
chemical energy high explosive antitank ammunition . It has two
12.7 - mm machineguns , one for antiaircraft and another mounted
coaxially with the main gun .
3. Strengths . The strengths of Threat main battle tanks are :
a. Low silhouette , which makes them harder to hit .
b. Simple fire control , which makes them easier to operate and
maintain .
c. Infrared night vision devices , which increase their
effectiveness at night .
d. Underwater snorkeling , which permits them to cross water
barriers quickly .
e. The high- velocity 115 -mm APFSDS tank- defeating round , which
travels a mile every second . The accuracy of this round
gives T - 62 tank crews a 50 % chance of hitting a stationary
target in the open with the first round at ranges to 1,500m ,
or a moving target traveling at a constant speed in the open
at ranges to 1,000m .
THE HVAPFSDS IS THE FASTEST TANK CANNON ROUND IN THE WORLD .

NO 4. Weaknesses . The weaknesses of Threat main battle tanks are :
a. T- 62
BV Threat tank fighting com
? partments are considerably
smaller than those in US
tanks , The crew is cramped
ted and freedom to Move is
restricted . Crew fatigue can
therefore be a bigger factor
in Threat tanks .
40
b. Smaller turret interior and
larger ( 115 - mm ) main gun
and ammunition means that Threat
tanks have a slower rate of
fire than US tanks .
eir
c. Because of its small fighting
compartment , the T - 62 tank M60A1
1 has 23 fewer rounds of main
gun ammunition than the
M60A1 . Therefore , in tank
duels Threat tanks may run
out of ammunition sooner than
US tanks .
63
d. Some main gun ammunition is
strapped along the turret
walls , and hits above the
turret ring
secondoni
Positions increase Threat crew vulnerability. A
penetration of the left front of the hull could hit
the driver and gunner; a penetration of the left
front of the turret could hit the gunner and TC .

DRIVE A TANK OVER VARIOUS TYPES OF TERRAIN
CONDITIONS
Acting as driver , and given a tank with crew .
STANDARDS
You must not deviate from the procedure outlined in the performance
measures .
PERFORMANCE MEASURES
1 . Drive vehicle over various types of terrain .
a. Refer to the operator's manual for information on the
controls , gages , and instruments used to drive and maneuver
the tank under all conditions .
b. You should choose a gear that allows you to maintain momentum
without injuring crewmen . Select the proper gear according
to the chart below :
SHIFT MINIMUM MAXIMUM GROUND
RANGE SPEED SPEED CHARACTERISTICS
Low O mph 10 mph mud , snow , deep sand ,
steep grades
High 0 mph 30 mph semihard or hard surface
moderate slopes , rolling
terrain
Reverse 0 mph 5 mph as needed
.
2
Select a good route .
a. Take advantage of all possible cover and concealment ( see
Task Summary 171-121-1003 , Negotiate a Route Using Terrain
for Cover and Concealment ) .
2-420 FM 17-19F
TASK SUMMARY 171-139-1005 ( cont )
PERFORMANCE MEASURES ( cont )
b. Keep the tank as level as possible when driving in order to
keep the gun level ( avoid trunnion cant ) , especially at
temporary halts in an overwatch position .
3. Drive the tank in sandy terrain .
a. Before entering sand , select a gear that will allow the tank
to keep its forward momentum without spinning the tracks .
This will minimize any change of gears .
b. Shake the tank
tank with
with the
the steering controls or back up in
reverse to throw off any sand that has built up between the
rear sprockets and the tracks . This build - up causes a lack
of steering response , and excessive build - up may throw the
track .
C. Drive on available vegetation when possible ; this will reduce
the excessive track wear caused by sand .
4. Drive the tank in rocky terrain .
3
a.
Avoid rocks as much as possible , especially the largest ones .
Rocks will cut rubber from track blocks and road wheels ; they
can bend or break center guides and can throw the track .
b. Keep your speed down to reduce the impact of the track with
the ground . At slower speeds rocks that are picked up by the
track will not be thrown into the suspension and cause
damage .
5. Drive the tank in marshy terrain .
a. Avoid marshy areas where possible ; marshes ( and tundra in
arctic areas during thaws ) can cause vehicles to bog down and
become immobile .
b. Cross such terrain by following a straight , steady course and
maintaining momentum . Avoid spinning the tracks .
c. When a tank is mired so that it cannot proceed under its own
power , do not continue attempts to get it out without
assistance . Continuing to spin the tracks will only dig it
in deeper
6. Drive the tank in mud , sand , and snow .
a. Avoid unnecessary halts or changes in direction .
b. Reach a speed that lets the tank move without spinning the
tracks or losing control in a skid . Should the vehicle skid ,
do not try to apply the brakes ; instead , decelerate and try
to regain control .

7. Drive the tank under unusual weather conditions .
a. After а shutdown period in extremely cold weather , drive
slowly for about 100m . This will warm up the lubricants and
prevent breaking parts .
b. In extremely hot weather , avoid the continuous use of low or
reverse at high engine speeds whenever possible . This will
help prevent overheating of the engine .
8. Drive a vehicle over manmade and natural obstacles .
a. Cross a ditch or crater .
( 1 ) Enter the ditch slowly , and as squarely as possible ( fig

c. Drive the tank up a steep slope .
(1 ) Place transmission in low 30 that the tank will not
require manual shifting during the climb .
(2) Drive a straight course up the slope . ( Steering reduces
the tank's ability to climb . )
Drive the tank on a slide slope ( along the slope instead of
up or down it ) ,
( 1 ) Keep the tank straight . This will reduce its tendency
to drift down the slope .
(2) Make smooth corrections in steering , avoiding abrupt
turns which may throw a track ,

TASK SUMMARY 171-139-1008 ( cont )
PERFORMANCE MEASURES ( cont )
CAUTION : Avoid traversing turret with turret seal inflated . If the
tank should enter water deeper than four feet , do not stop
engine while it is submerged . Protection of the engine
exhaust system against the entry of water is dependent on the
exhaust pressure , which requires the engine to be operating
continuously . Should the engine accidently stop while it is
submerged , do not attempt to re - start the engine . The tank
should be towed out of the water as soon as the tactical
situation permits. If it becomes necessary to stop forward
movement of the tank while the engine is submerged , place
transmission shift lever in H ( high ) . Apply and hold brakes ,
depress accelerator , and engine accelerator pedal locking
lever to maintain engine speed at 1,000 rpm .

DETERMINE THE GRID COORDINATES OF A POINT ON A MILITARY MAP
USING THE MILITARY GRID REFERENCE SYSTEM
CONDITIONS
Given a standard 1 : 50,000 scale military map , a 1 : 50,000 grid
coordinate scale , a pencil and paper , and a point ( such as Point A ) on
the map which is labeled for identification .
STANDARDS
Within 2 minutes , determine the six - digit grid coordinates for a point
to within 100 meters ( grid coordinates must be preceded by the correct
two - letter 100,000 - meter- square identifier ) .
PERFORMANCE MEASURES
To
T herkeep from getting lost you have to know how to find your location .
e are
no street addresses in a combat area , but the military map
can spot your location accurately . It has black lines running up and
down (north and south) and crosswise ( east and west ) . They form small
squares called grids .
These lines are numbered along the outside edge
of the map picture .
Using these numbers you can name each square ( fig
1) . No
two squares have the same number . To get the correct number
for a certain grid square , first read from left to right along the
bottom and find the line that borders your grid square on the left .
Then read
along the up and find the east - west line that borders your grid square
bottom . Always read right , then up .

Grid square 1181 gives your general neighborhood , but there is a lot
of area inside that grid square . To make your address more accurate ,
just add another number to the first half and another to the last
half-- 30 your address has six numbers instead of four .
Here's how to get those extra numbers . Pretend that each grid square
has ten lines inside it running north and south , and another 10
running east and west . This makes 100 smaller squares . You can
estimate where these imaginary lines are .
Note . These six numbers are called coordinates ; they give your
location to within 100 meters .
Suppose you are halfway between line
11 and line 12 . Then the extra
number is 5 and the first half of 82
your address is 115 . Now suppose you
are also 3/10 of the way between line
81 and line 82 . Then the second half
of your address is 813 . ( If you were
exactly on line 81 the second part
would be 810. ) Figure 2 shows that
if you were located where the dot is 81
in grid square 1181 , then your
address would be 115813 .

DETERMINE THE ELEVATION OF A POINT ON THE GROUND USING A MAP
CONDITIONS
Given a standard 1 : 50,000 scale military map , pencil , a designated
point on the map , and a requirement to determine the elevation of that
point .
STANDARDS
Within 1 minute , determine the elevation of the designated point to
within 1/2 of the value of the contour interval .
PERFORMANCE MEASURES
To determine the elevation of a point on a map :
1 . Locate the point on the map . ( It may already be plotted on the
map , or given as an eight - digit coordinate . )
2. Determine the contour interval of the map from the marginal
information .
3. Locate the index contour line nearest the
the point
point for
for which the
elevation is being sought .
4. Count the number of contour lines that must be crossed to go from
the numbered lines to the point and note the direction -- " up " or
" down . "
a. If the point is on contour lines , its elevation is that of
the contour .
b. For points between contours :
( 1 ) Points less than one- fourth the distance between lines
are considered to be the same as the elevation of the
nearest line .
(2) Points one - fourth to three - fourths the distance from the
lower line are considered to be at an elevation half the
contour interval above the lower line .

c. To estimate the elevation of the top of an unmarked hill , add
half the contour interval to the elevation of the highest
contour line around the hill .
d. To estimate the elevation of the bottom of a depression ,
subtract half the contour interval from the lowest contour
around depression .
e. On maps that do not show elevation and relief in as much
detail as needed , supplementary contour lines may be used .
Marginal information indicates the interval , and the
supplementary lines are used exactly like solid contour
lines .
f. Bench marks and spot elevation also indicate points of known
elevation .
А.
Figure 1 .
Note . The brown lines on the map are called CONTOUR lines .
Each line shows the height above sea level . Contour
lines never cross one another . Printed at the bottom
of the map is the CONTOUR INTERVAL , which is the
difference in height ( elevation ) between one brown
line and the one next to it . On a map with a scale of
1 : 50,000 contour interval is usually 20 feet . This
would make point " A" 80 feet higher or lower than
point " B " .

You tell from the brown lines whether it's uphill or downhill . Every
fifth line is heavier than the rest and has a number that gives its
elevation ( fig 2 ) . Let's say that the contour interval is 20 feet
again . You can tell that point " A " is 80 feet higher than point " B" .
Also , if you know the ground distance between " A " and " B " , you can get
an idea of how steep the slope is . Contour lines widely spaced show a
gentle slope . When they are close together the slope is steep ( see
fig 3 ) .

MEASURE DISTANCE ON A MAP
CONDITIONS
Given :
1. A standard 1 : 50,000 topographic map on which is plotted :
a. Point A and Point B , 3,000 to 4,000 meters apart .
b. Point C and Point D , 3,000 to 4,000 meters apart , on a road
( trail ) which changes direction at least twice .
2. A strip of paper with a straight edge .
STANDARDS
1. Determine the straight - line distance , in meters , from Point A to
Point B within 50 meters , in 3 minutes .
2. Determine the road ( curved - line) distance from Point C to Point D
within 100 meters , in 3 minutes .
PERFORMANCE MEASURES
1 . You can use your map to measure distance-- how far it is between
two places , The map is drawn to scale , This means that a certain
distance on the map equals a certain distance on the earth . The
scale is printed at the bottom and at the top of the map , like
this-- Scale 1 : 50,000 .
2. This means that 1 inch on the map equals 50,000 inches on the
ground , In fact , any ground distance equals 50,000 times that
distance on the map .
Note . Make sure you have located the meter sgale on the
particular map you are using . Military maps have different
scales and you must use the meter scale to determine the
proper distance between two points in meters .

Suppose you want to find the
distance between A and B around
a curve in a road ( see fig 4) .
Take a strip of paper , a make
1000 0 1000 small tick mark on it , and line
500
up the tick mark with Point A.
SO
Align the paper with the road
edge until you come to the

repeating this until you get to
Point B. followw the

road edge with your paper .
Make a mark on your paper where
it hits B , and then go to your
bar scales to get the distance .
Figure 3 .
Normally , you will be required to measure distance in meters , and you
may receive a problem that goes off the bar scale . The meter bar
scale allows you to measure distances up to 5,000 meters . If you have
to measure distances greater than 5,000 meters , follow these steps :
a. Place your starting point on the paper under the zero on the
bar scale . Measure off 4,000 meters and place a new tick
mark at that point on your paper .
b. Place this second tick mark also under the zero on the bar
scale and determine if the distance on the paper now falls
within the bar scale . If it does , add this value to 4,000 to
give you your total distance . If it does not , repear step a
until the distance on the paper falls within the bar scale .
Remember to add this last value to the total number of meters
your've already measured .

ORIENT A MAP USING A COMPASS
CONDITIONS
Given a standard 1 : 50,000 scale military map and lensatic compass , in
a field environment , under daylight conditions .
STANDARDS
Within 1 minute , orient the map to the ground using a compass so that
the north - seeking arrow of the compass is within 3 degrees of the
angle shown in the G -M angle of the declination diagram shown on the
map .
PERFORMANCE MEASURES
1 . With the map in a horizontal position , the compass is placed
parallel to a north- south grid line with the cover side of the
compass pointing toward the top of the map . This will place the
black index line on the dial of the compass parallel to grid
north . Since the needle on the compass points to magnetic north ,
we have a declination diagram on the face of the compass formed by
the index line and the compass needle .
2. Rotate map and
and compass until the directions of the declination
diagram formed by the black index line and the compass needle
match the directions shown on the declination diagram printed on
the margin of the map . The map is then oriented .
3. If the magnetic north arrow on the map is to the left of grid
north , the compass reading will equal the G - M angle ( given in the
declination diagram ) . If the magnetic north is to the right of
grid north , the compass reading will equal 360 ° minus the G -M
angle .
4.
Remember to point the compass north arrow in the same direction as
the magnetic north arrow (2 above ) , and the compass reading ( equal
to the G -M angle or the 360 minus G M - angle ) will be quite
apparent .

5. Some maps have a built - in protractor consisting of a pivot point
" P " on the south neatline of the map and several degrees of arc
along the north neatline of the map . The G -M line is obtained by
connecting pivot point " p " with the appropriate value of the G-M
angle ( taken from the declination diagram ) on the arc . The map
may then be oriented by placing the compass parallel to this line
and rotating the map and compass until the needle point is aligned
with the continuous line formed by the index line and the sighting
wire . The map is then oriented .
6. An alternate method is to draw a magnetic north line on the map
from any N - S and E - W grid line intersection using the protractor .
Align the straightedge of the compass along this magnetic north
line and rotate the map and compass together until the north arrow
falls beneath the fixed black index line on the compass .
Note . If G -M angle is less than 3 degrees , do not line up north
arrow .

CONDITIONS
Given a standard 1 : 50,000 scale military map in a field site , under
daylight conditions .
STANDARDS
You must orient the map to north within 30 ° in 10 minutes .
PERFORMANCE MEASURES
There are many good ways that you can use to locate your position on
your map , but first you have to do one important thing . Point your
map so that NORTH , SOUTH , EAST , and WEST on the map point the same way
as they do on the ground . This is called orienting your map .
Look at the map and the ground to find two linear features common to
both , such as hilltops , saddles , valleys , ridges , and depressions . Ву
aligning the features on the map with the same feature on the ground
( figs 1 and 2 ) , the map is oriented .

USE AN AUTOMATED CEOI
CONDITIONS
This task is performed under all weather conditions in a field or
garrison location . Your tank commander will provide you with an
automated CEOI , scratch paper , and a pencil .
STANDARDS
The task standard has been met when , in 5 minutes , you have used the
automated CEOI to determine your call sign , operating frequency , and
suffix item number identifier , and you have entered a net in which you
do not normally operate in accordance with performance measures 1
thru 5 below .
PERFORMANCE MEASURES
1 . Determine call signs .
a. To find the call signs for a given element , turn to the index
( fig 1A ) of the CEOI . Follow the left - hand column of items
until you find the unit you are looking for .
EXAMPLE : 1-77 INF BN , A CO , 1ST PLT . After finding the
unit , look in the right - hand column under ITEM NO
heading to find the correct page and turn to that
page ( fig 4A ) .
b. Determine the correct time period ( 01 ) and look under the
column for that time period . After finding the call sign for
that unit ( call sign for 1ST PLAT , A co , 1-77 INF BN is J1M ) ,
go back to the index ( fig 1A ) and find the ITEM NO for
SUFFIXES . Turn to that item number ( fig 2A ) and find
PLT / SEC / TEAM LDR . Located to the left of PLT / SEC / TEAM is the
two - digit suffix for PLT / SEC / TEAM LDR . You now have the
five- character call sign for the PLT LDR of the 1ST PLAT , A
CO , 1-77 INF BN ( J1M13 ) .

2. Determine operating frequency .
a. Frequencies are assigned to each radio net according to
command echelon .

b. To find the frequency for a given net , turn to the index ( fig
1) of the CEOI and find the organization you wish
wish to
communicate with .
EXAMPLE : A CO , 1ST PLT , 1-77 INF BN . Turn to that item
number ( fig 4B ) . Look under the left - hand column
until you find the unit you want to communicate
with ( A CO , 1ST PLT , 1-77 INF BN ) . After finding
the unit , look to the right under the correct time
period ( Day 01 ) . The frequency for A Co , 1ST PLT ,
1-77 INF BN is 52.450 MHz .

Determine ITEM NUMBER IDENTIFIERS .
a. Unknown station call signs can be identified by use of the
ITEM NUMBER IDENTIFIER .
b Each station should know the two - letter identifier for its
own net for each time period . To find your ITEM NUMBER
IDENTIFIER , follow these steps :
STEP 1 : Go to the index of your CEOI ( fig 1B ) and find ITEM
NUMBER IDENTIFIER and the page where it is located in the
CEOI .
STEP 2 : Turn to the correct page for identifiers in your
CEOI ( fig 7 ) and read down the appropriate time period column
until you find your CEOI item number . Then follow that line
to the far left column of two- letter identifiers . This is
your item number identifier for that time period . You will
use this identifier when entering a net in which you do not
normally communicate . When you enter such a net , you will be
asked by the NCS to identify your station by referring to the
item number identifier . Send this two - letter identifier .
This provides the NCS of the other net with your CEOI item
number , and by referring to that item , the NCS can readily
identify your station .
4. Enter a net in which you do not normally operate .
a. When entering a net in which you do not normally operate , use
the following procedures :
FM 17-19F 2-469
TASK SUMMARY 113-573-8001 ( cont )
PERFORMANCE MEASURES ( cont )
SITUATION : You are the driver / radio operator for the CDR , B
CO ,1-77 INF BN , with a requirement to enter the 1-79 INF BN
CMD net , a net in which your commander does not normally
communicate , and send a message to the CDR , CO B. ( Time
period is 01 , first day of the month . ) The 1-79 INF BN call
sign is C3056 ( fig 5 and fig 2A ) and your CDR is Y6Y75 ( fig
4A and fig 2B ) .
STEP 1 : Go to the index of your CEOI ( fig 1B ) and find the
item number identifier page , turn to that page ( fig 77 ) , and
determine your two - letter identifier ( AB ) .
STEP 2: Determine the operating frequency of the NCS of the
1-79 INF BN as described in performance measure 2 and call
the NCS station :
EXAMPLE : CHARLIE THREE OSCAR FIVE SIX -- ( THIS IS ) YANKEE
SIX YANKEE SEVEN FIVE -- REFER TO ALPHA BRAVO -- I
HAVE TRAFFIC FOR VICTOR ZERO CHARLIE SEVEN
FIVE -- REQUEST PERMISSION TO ENTER NET-- OVER
Note . Before transmitting , monitor the frequency to
make sure you do not cut in on someone else's
transmission ,
STEP 3 : The NCS will require you to authenticate prior to
giving you permission enter
to enter the net . Refer to the
explanation of correct authentication procedures in Task
Summary 113-573-4002 , Use KAL- 61B and KTC 1400 Numerical Code
to Authenticate Transmissions and Encrypt / Decrypt Numbers and
Grid Zone Letters . After permission is granted to enter the
net , contact the station for which you have traffic , and send
your message .
b. Upon completion of your message , advise the NCS that you are
leaving his net . You may or may not be required to authenti
cate your departure .
5. Determine identification of an unknown station . To determine the
identification of an unknown station , by use of item number
identifiers , use the following procedure :
2-470 FM 17-19F
TASK SUMMARY 113-573-8001 ( cont )
PERFORMANCE MEASURES ( cont )
SITUATION : You have just received a call from an unknown
3 station . The individual identified himself by utilizing his
call sign of A8C69 and stated that his item number identifier
is AB . It is the second day of the month ( 02 ) and the
individual authenticated correctly when you challenged him .
To find out who the individual is , perform the following
steps :
STEP 1 : Go to your CEOI index ( fig 1 ) and locate the page of
ITEM NUMBER IDENTIFIERS . Turn to that page ( fig 7 ) , then
look down the left - hand column until you find the two - letter
item number identifier ( AB ) , follow this column across to
time period 02 , this will give you the the correct
correct CEOI item
number of the unknown unit ( 19B ) .
STEP 2: Turn to the CEOI
item number page for the station
calling ( 19B ) ( fig 6 ) . Look under the correct day ( 02 ) for
the first three characters of the unknown call sign ( A8C ) .
1 You find this then to be the 52 S& T BN .
STEP 3 : To determine who in the 52 S& TBN is calling you ,
look at the last two characters of the call sign ( 69 ) . Go to
the CEOI item for SUFFIXES , day 02 ( fig 3 ) , read down the
left - hand column until you find the last two characters . You
can now determine the identity of the unknown station to be
G2 / S2 of the 52 S& T BN .

receiver , rear sight assembly , cocking handle , and carrying
handle . General disassembly of the M60 is completed after
the removal of the other seven groups from the receiver
group .
2. Clean the M60 .
a. The M60 machinegun should be kept cleaned at all times . If
the gun is not being used for training or firing , it should
be inspected weekly and cleaned and lubricated as necessary .
At least once every 90 days it should be cleaned as
thoroughly as if it were just fired .
b. If the gun has been fired , follow the steps outlined below :
(1 ) Break the gun down into its eight major groups .
(2) Using a cleaning rod and patch soaked in cleaning
compound solvent ( CR ) , swab out the bore several times
until most of the powder fouling is removed .
(3) Using a rag soaked in CR , clean the chamber and the bolt
until most of the visible powder fouling is removed .
(4) Using a rag soaked in dry cleaning solvent ( SD ) , wipe
down all parts of the gun and the tripod with the
exception of rubber coated parts .
(5) Dry completely all parts cleaned with SD .
(6 ) Second day -- repeat procedures outlined for day 1 .
(7) Third day-
( a) Using a cleaning rod and patches soaked in rifle
bore cleaner ( RBC ) , swabout the bore of the gun
until all powder fouling is removed . Then swab the
bore out with clean patches until it is completely
dry .
Note . Be sure to duplicate all bore cleaning steps
on spare barrel .

c. If the gun has not been fired-
( 1 ) Inspect weekly and clean the gun as outlined in perfor
mance measure 2b ( 7 ) above .
(2) If the gun has not been fired in the last 90 days , clean
it using the complete procedure in performance measure
2b above .
d. Important points to remember .
( 1 ) Do not submerge the buffer group in any cleaning
solvents . Clean as prescribed in above outlined
procedures .
(2) Use of gasoline , kerosene , benzene , or high pressure
water , steam , or air is prohibited for cleaning .
(3) When cleaning the barrel assembly , care should be taken
to prevent getting any solvent or oil in the gas
cylinder . This is easily done by keeping the barrel in
an inverted position while cleaning .
(4) SD is flammable .
e. Lubrication :
(1 ) Using general purpose lubricating oil ( PL special ) , run
a cleaning patch with several drops of PL special on it
through the bore .

rides feed pawl carrier on underside of cover
assembly .
f. Special considerations for lubrication must be taken in
climates with extreme temperatures ( refer to FM 23-67 , chap
5 , sec II , p 53 ) .
8. Make sure of proper care and use of the barrels .
( 1 ) To prolong the life of the barrels , to retain accuracy ,
and to allow continuous firing for prolonged periods ,
two barrel assemblies are issued with each gun .
(2) During continuous firing , change barrels every 10
minutes when firing at the sustained rate of 100 rounds
per minute ; every 2 minutes when firing at the rapid
rate of 200 rounds per minute ; and every minute when
firing at the cyclic rate which is in excess of 550
rounds per minute .
3. Inspection ( machinegun and tripod ) . A detailed inspection check
list can be prepared by consulting FM 23-67 ( w / C1 , chap 4 , sec II ,
pp 51 thru 53 ) .
( 1 ) This will give you correct nomenclature ,
(2) It will also give you the correct functioning for the various
parts .

3. Apply correct traversing and search techniques .
a. Traversing . This is moving the muzzle of the weapon to the
left or right to distribute fire laterally . With the
bipod - mounted gun , this is accomplished by selecting
successive aiming points in the target area ( fig 3 ) . The
gunner shifts his shoulders slightly to the right or left for
minor changes . For major changes in direction , he moves his
elbows and realigns his body to remain directly behind the
gun .
b. Searching This is moving the muzzle of the weapon up or
down to distribute fire in depth and is accomplished by
selecting successive aiming points in the target area ( fig
3) . To make changes in elevation , the gunner moves his
elbows closer together or farther apart .
4 . Use observation and adjustment of fire .
a. Observation of Fire . Machinegun fire is observed by noting
the strike of the projectiles in the target area , by
observing tracers in their flight or , in the case of the
10 -meter range , by noting the holes made in the target .
b. Adjustment of Fire . When firing the bipod -mounted gun , fire
is adjusted by changing the gunner's body position by using
the traversing and searching method .
5. Apply the adjusted aiming point method .
a. The adjusted aiming point method is a means of rapidly and
accurately adjusting fires without going through the process
of making sight adjustment .
