2. OPERATING INSTRUCTIONS Section Secti on I. PREOPER PREOPERATIONAL ATIONAL INSPECTIONS 2-1. INTRODUCTION
Now that you are familiar with some of the basic characteristics and capabilities of the M202Al rocket launcher, you are ready to prepare the M202Al for operation. However, before placing the launcher into operation, you should perform a preoperational inspection and function check. 2-2. PREOPERATIONAL INSPECTION INSPECTION
a. Visually inspect the exterior of the launcher for damaged, loose, or miss issing ing parts; parts; dents; dents; cracks; separat separations; ions; and loose loose fiberglass fiberglass.. Also, Also, check next to the data plate, on the left side of the launcher, to insure that both MWOs have been apphed. If so, there will be a number two (2) stamped after the MWO number. If not, turn the launcher in to maintenance for application of the MWO. b. Check the reflecting sight for defects such as dents and missing or loose parts. Insure that the sight lock (18, fig 1-1) can be placed into both the firing and stowed positions. With the sight in the firing position, lift the lens cover. Sight through the lens and check for improper alignment of the reticle, obscured vision, or a broken reticle. 2-3. FUNCTION CHECK
After you have completed the exterior examination, you must perform a function check. a. Unfasten the latch on the rear dust cover and rotate the cover down. Insure the latch, hinge, and cover are serviceable. b. Check the front cover trigger-handle interlock system as described below: (1) Unfasten the latch on the front dust cover (2, fig 1-1),rotate the front cover handle (1, fig 1-1) outward until it stops, and rotate the front cover down below the launcher tubes, applying sufficient pressure to -release the trigger-handle (14, fig 1-1) from its retracted position. NOTE: If the trigger-handle will not release, check to insure the front cover is in a fully locked position.

(3) To prevent an accidental firing when pressing on the rocket clip to insure it is locked onto the firing pin housing, check that the firing pins do not extend more than I/8-inch past their -rubber seals. c. To check the firing pin mechanism assembly (fig 2-1) and trigger safety (fig2-2), proceed with the following steps: (1) Grasp the firing pin mechanism housing (4, fig 2-1) and fully extend it from the launcher, holding it firmly. Do not allow the firing pin housing to rotate. (2) Place P lace the trigger trigger safety safety to the the rear (fire) position position and pull the trigger. (3) Upon firing, the firing pin should protrude from the housing. This may be observed from the rear of the launcher. (4) Move the trigger trigger safety to to the forward (safe) position. pos ition. Pull P ull the trigger. The trigger should not operate. (5) Retract the firing pin housing back into the launcher. Figure 2-1. 2-1. Firin Firin g pi n m echanism echanism assembly. assembly.

d. Inspect the interior of the launch tubes for dents or cracks; raveled, frayed, or loose fiberglass; or visible signs of bums in any tube. Check for sand, dirt, or other foreign matter which could damage the rocket warhead when fired. 2-4. ROCKET CLIP INSPECTION
When satisfied with the inspection and functioning of the rocket launcher, inspect the rocket clip for defects such as leaking rockets, loose warheads, bail not under spring tension, dented rocket canister, rust or corrosion, or other foreign matter such as sand or dirt. Insure the clip latch is present and each rocket has a retainer. If the clip latch (6, fig 1-2) is missing from the clip manifold (9, fig 1-2), a spare latch is stored in the rear cover of the launcher (10, fig 1-1).
Section Secti on II. ENGAGING ENGAGING TARGETS TARGETS 2-5. LOADING
Once you are satisfied with the inspection of the rocket clip, you are then ready to load the launcher. The following procedures should be used in loading the clip into the launcher.

TC 23 23-2
a. Place the trigger safety in the "SAFE" position (fig 2-2). b. Pos P osition ition the the launcher on the ground, ground, resting on its (closed) (clos ed) front cover with the front cover handle in the stowed position (fig 2-3). c. Open the rear cover (5, fig1-1) by releasing rear-cover latch and rotate it down and beneath the launcher. d. Supporting the launcher with the left hand on the sight, partially insert the rocket clip into the rear end of launcher tubes (with bail toward rear dust cover) using rocket warheads as guides. e. Grasp the end of clip support strap nearest two black snaps (3, fig 1-2) and pull it outward to remove the strap and spacers from the clip. f. Once the support strap has been removed, depress the launcher clip lock button (9, fig 1-1). This will allow you to fully insert the rocket clip into the launcher. (You should hear a "click" as the clip latch locks onto the firing pin assembly. If not, press firmly on the rear of the rocket clip; the clip latch should lock onto the firing pin assembly. To check, pull outward on the bail. If the firing pin assembly remains attached to the clip latch manifold, the firing pin assembly is locked in position.)

Figure 2-3. 2-3. Loading Loading the clip into the launcher.
g. Make a manual and/or visual check to insure that the prongs of the clip latch are fully seated in the clip attachment slot of the firing pin mechanism assembly (fig 2-4). The launcher is now loaded. If the launcher is not to be fired right away, close and latch the rear cover, and the rocket system is ready for you to carry until an appropriate target is available. With the rocket clip in the forward position and the rear cover closed, the weapon is in a "safe" condition. Before you shoot the weapon, you must prepare it for firing.

NOTE: DO NOT attempt to pull trigger handle assembly down if front dust cover is not locked in the open position. To do so will prevent the dust cover from locking in the open position which will prevent the weapon from firing.
c. With thumb and forefinger, grasp the trigger-handle assembly immediately behind the locked front cover. Extend the triggerhandle, insuring it is fully seated in the firing position and the safety switch is in the SAFE position. Check the area to the rear of the launcher to insure that all personnel, material, and obstructions that would interfere or present a safety hazard are clear of the rear danger zone. P aragraph 2-14 provides provides additional additional information information on safety. Next, extend the sight by depressing the sight lock, and moving it to the rear detent position. Raise the protective lens cover and the launcher is ready to fire (fig 2-7).

2-7. SIGHTING EQUIPMENT AND AIMING
a. Reflecting sight assembly (fig 2-8). The sight is bore sighted at the factory and by organizational maintenance personnel as necessary. TM 31055-456-12 gives a detailed explanation of the procedure used by organizational maintenance personnel for bore sighting. The reflecting sight assembly consists of the-(1) Sight. The reflection sight has a ladder type reticle pattern (fig2-9) with curved stadia lines on both sides of the vertical center line. Current sighting procedures do not require use of the stadia lines to obtain approximate target distance. distance. P aragraph aragraph 2-8 discusses discusses techniques echniques of range range determination /estimation. The vertical range line is graduated in 100-meter increments from 0 to 500 meters from the top to the bottom of the sight reticle. On either side of the vertical range line are horizontal lead lines which aid the gunner in engaging moving targets. (2) Sight lock (11, fig2-8). The sight lock is a spring lock is a spring loaded arm used to lock the sight in either the stowed or firing position. (3) Mounting plate (1, fig2-8). The mounting plate contains an elevation adjustment plate which has two notches for placing the sight in the stowed or firing position. Also the plate allows adjustment to be made on the sight.

(2)Area-type targets. When engaging area-type targets, the weapon which poses the greatest threat should be engaged first. When the "greatest" threat is eliminated or does not exist, engage the target at the center of the near half of the target (fig 2-11). Figure 2-11 2-11.. Aimi ng point for areaarea-type type target.
c. Sight picture. A proper sight picture is obtained by centering the target within the sight reticle at the appropriate range. Figure 2-12 depicts the sight picture for a stationary target at 150 meters. Figure 2-12. Sight picture

TC 23 23-2
d. Applying lead. Each lead line or space represents 8 kph (5 mph) of apparent speed. Lead is applied to targets moving across the gunner's front. Determination of range and speed is discussed in paragraphs 2-8 and 2-9. (1) Targets moving directly across the gunner's front (fig 213 and 2-14). Estimate the target's speed as either slow (8 kph or less) or fast (9 kph or more). For slow moving targets locate the proper range mark on the vertical range line, locate the lead line which is horizontal to the range mark, place one lead line distance on center of mass of the target and fire. For fast moving targets use the same procedure as for slow targets except that the lead line is placed on the front leading edge of the target. Be sure to select the left or right lead line which places the vertical center line in front of the target. NOTE: Figure 2-13. Target moving across gunners Front (slow target). target).
Figure 2-14. Target moving across gunner's Front (fast target)
(2) Target moving at an angle toward or away from the gunner (fig 2-15 and 2-16). If more of the vehicle's side is visible than its front or rear, engage the target as if it were moving directly across your front. The fast or slow speed determination will be based upon the target's speed straight across your line of fire. If more of the front or rear is visible
2-12

2-8. RANGE RA NGE DETERMINATION.
The The probab obabil ilit ity y of hitt itting ing any any targ arget with ith the M20 M202Al rock ocket laun aunche cher is greatly atly increased if the gunner actually knows the range of the target. It is important that methods of range determination be taught and frequently used by all soldiers who may have to employ the M202AI. Some of the methods of determining the range to targets are rangefinders, measurement of the distance by map inspection, intersection using compasses, pacing, use of direct fire weapons such as machineguns, or visual range estimation. Visual range estimation is the least desirable method due to its inaccuracy; however, in the offense or in a hasty defense, it may be necessary to use this method. Therefore, all troops should receive training and frequent practice in the methods of visual estimation of range. Two methods are: a.100-meter unit-of-measure method. To use this method, the soldier must be able to visualize the number of 100-meter increments on the ground between his position and the target. A more detailed explanation of this method can be found in FM 23-9, para 6-8c (2) (a). b. The appearance-of-objects method. It is often impossible to see all of the terrain to the target, which makes it impractical to apply the 100-meterunit-of-measure method. Ranges must then be
2-13
TC 23 23-2
estimated by the appearance of-objects method. To use this method, the soldier, must learn through practice how familiarobjects look at various known ranges. For example, he studies the appearance of a man standing 100 meters away and fixes his appearance firmly in mind--his size and the details of his uniform and equipment. Next, he studies the man in a kneeling position, then in a prone position. This same procedure is followed at various known ranges out to 500 meters. By comparing the appearance of the man in these positions at known ranges, the soldier can establish a series of mental images which will help him to estimate range on unfamiliar terrain out to 500 meters. Training should also include the appearance of other familiar objects such as weapons and vehicles. Factors which affect the appearance of objects are shown in table 2-1. Table 2-1. Factors Affecting Range Estimation.

2-9. SPEED DETERMINATION
a. Although the M74 rocket was designed primarily as a flame/ antipersonnel round for use against stationary targets, it may be used effectively against enemy vehicles carrying troops, ammo, or other supplies. Normally, these targets are in motion and accurate engagement depends upon the gunner's ability to determine speed as well as range. b. The The ability to determ determine ine speed is developed by constant constant practice. The soldier should begin by determining the speed of vehicles at known ranges and moving in a constant direction. As the soldier improves, the range, direction, and type of vehicles can be varied. c. One method of determining target speed is to compare the speed of the target with the speed of a running man. If the target is traveling at the speed of a jogging man or slower, its speed is about 8 kph or less and the gunner should use the slow speed lead. If the target is traveling at the speed of a slow running pace or faster (9 kph or more), the gunner should use the fast speed lead. Due to the difference in size between a man and a vehicle, a gunner may tend to underestimate the vehicle's speed, but this can be corrected with practice. 2-10. SPECIAL AIMING TECHNIQUES TECHNIQUES
a. Targets at a range of 500 meters or less. When firing on targets at 500 meters or less and the first round misses, the burst-on-target technique of fire should be used to gain a second round hit. The
2-15
TC 23 23-2
burst-on-target technique is very easily applied by following the procedures below: (1) After firing the weapon, hold your original sight picture until the rocket impacts. (2) Note the point on the sight reticle where the round burst appears (fig 2- 17) and move this point onto the center mass of the target (fig 2-18). (3) Fire again. This should give you a target hit; if not, apply the same principle (steps 1 and 2) and fire again--this time you should have a target hit. Figure 2-17. Burst-on-target aiming technique.
Figur e 2-1 2-18. 8. Center Center of m ass of target.
b. Targets at ranges beyond 5OO meters. At ranges beyond 5OO meters and out to 700 meters, the M202Al rocket launcher can be used to suppress enemy troops in fortified positions or wooded areas with smoke and flame. To sight on target areas beyond 500 meters, the gunner should center the target in the bottom of the sight (fig 2-19 and 2-20). If he misses with his first round he should observe the round burst on his sight and try to move that point onto his target. Since the reticle is graduated only out to 500 meters, the
2-16
TC 23 23-2
burst may appear within the sight but not within the sight reticle itself. Figur e 2-19 2-19.. Woodl ine at 600 600 meters

The The gunner must hold old the M20 M202A1 ste steady ady while firin iring g to obt obtain ain an accu accurrate ate first round and to properly employ the burst-on-target technique. The following principles of steady hold should be applied. a. Whenever possible, fire from a supported position. A stable weapon delivers a more accurate shot. b. Don't breathe during aiming and firing. Chest movement in and out will make aiming difficult. c. Relax; muscle strain or tension causes trembling. d. P Pull ull the trigger; trigger; don't jerk it. it. J erking will will pull the weapon weapon off target. e. With the left hand, hold the weapon so that the rear dust cover rests snugly against the right shoulder. 2-12. TRIGGER TRIGGER MANIPULATION MA NIPULATION
Now that you know the sighting procedures, how to adjust fire, and understand the principles of holding the weapon steady, you are ready to fire the weapon (fig 2-21). To do this, release the trigger safety by moving the switch to the rear, then using two fingers and applying a smooth and steady rearward pressure, squeeze the trigger fully. After each rocket has fired, relax your fingers to allow the trigger to return to the fully forward position. This method must be repeated to fire each of the rockets. Only one rocket can be fired with each trigger squeeze.

Section III. MISFIRES, MALFUNCTIONS, AND SAFETY 2-15. MISFIRE
A failure to fire may be caused by a faulty firing mechanism or a faulty element in the propelling charge explosive train. 2-16. MISFIRE PROCEDURES
When a misfire occurs, you should take the following actions: CAUTION: Do not assume that an initial failure of a round to fire is a complete misfire--it could be a hang fire or a mechanical delay. However, the misfire procedures outlined below are appropriate for either a complete misfire or a hang fire. a. In combat.
(1) Squeeze the trigger four times after the last misfired rocket. If this clears the weapon, remove the empty clip and inspect the launcher before firing again.
2-19
TC 23 23-2
(2) If this does not clear the weapon, place the trigger safety in the SAFE position, keeping the weapon pointed toward the enemy, lower it from your shoulder and place it on the ground, resting on the front and rear dust covers. (3) Grasp the side of one clip tube and remove the clip latch to separate the firing pin mechanism from the clip. If separation does not occur, carefully insert a knife blade between the firing pin mechanism and clip manifold and apply pressure to obtain at least a 1 -inch separation between the two. (4) Depress the clip lock button, grasp either of the top two rocket tubes, and remove the clip. NOTE: Failure to depress the clip lock button will cause damage to the launcher.
(5) Place P lace the rocket clip on the ground as far away from your position as practical (60 meters desirable). Dispose of the rocket clip as described in paragraphs 3-3 to 3-5. (6) Inspect the launcher prior to loading again. In a training environment (1) Shout "MISFIRE" to warn all personnel that you have a misfire. Keep the launcher pointed at the target. (2) Squeeze the trigger four times after the last misfired rocket. if this clears the weapon, remove the empty clip and inspect the launcher before firing again. (3) If this does not clear the weapon, place the trigger safety in the SAFE position and keep the weapon on your shoulder pointed down range for 1 minute. (4) Keeping the weapon pointed down range, lower it from your shoulder and place it on a firm surface resting on the front and rear dust covers. (5) Grasp the side of one clip tube and remove the clip latch to separate the firing pin mechanism from the clip. If the separation does not occur, carefully insert a knife blade between the firing pin mechanism and clip manifold and
2-20
TC 23 23-2
apply pressure to obtain at least a 1-inch separation between the two. (6) Depress the clip lock button, grasp either of the top two rocket tubes, and remove the clip. NOTE: Failure to depress the clip lock button will cause damage to the launcher.
(7) Dispose of the rocket clip in accordance with your installation/unit SOP, AR 75-1, and TM 3-1055-456-12. (8) Inspect the launcher prior to reloading. 2-17. LEAKING ROCKET
A leaking rocket is characterized by burning fuel coming out of the rocket warhead. This can happen in three different situations: a. Before loading the rocket clip--immediately take cover at least 60 meters from the rocket clip. Do not move in front or to the rear of the rocket clip. Wait until the rocket clip stops burning. b. While loaded in the launcher without the clip being extended-place the launcher on the ground. Evacuate the area at least 60 meters and take cover. Do not move in front of the launcher or into the rear danger-zone area. c. When the rocket is fired--keep the launcher pointed toward the target area and pull the trigger to clear the weapon. If this clears the weapon, and triethylaluminum (TEA) is on the launcher, place the launcher on the ground and allow the TEA to bum itself out. If the weapon cannot be cleared of all rockets follow the procedures in 217b above. 2-18. DAMAGED ROCKETS
a. If in combat the rockets become damaged by shrapnel or small arms fire the following actions should be taken: (1) Defense--drop the launcher in the fighting position and move to an adjacent position. (2) Offense-drop the launcher on the ground and continue the attack.
2-21
TC 23 23-2
b. In a training situation, insure that all personnel take cover as far as possible from the damaged rocket. Let the rocket burn out and then dispose dispose of the the unexpended unexpended rounds rounds in accordance with with local SOP SOP . 2-19. SAFETY
a. Back Back blast area (fig 2-24). Propellant P ropellant gase gases s escaping escaping to to the rear of the the launcher can cause severe injury to personnel and damage to equipment located close to the firing position. The total back blast area extends 40 meters to the rear with a base of 38 meters. Figur e 2-24 2-24.. Back b last area. area.
(1)The danger zone extends 15 meters to the rear with a base of 15 meters. All personnel, equipment, and flammable materials must be kept clear of this area. (2) The caution zone extends an additional 25 meters with a base of 38 meter meters. s. P ersonnel in this area could be injured from secondary missiles thrown to the rear by the blast. (3) In a tactical situation, it is unlikely that the back blast area will be completely clear. Consequently, the launcher may be fired without injury to the firer as long as any rear vertical obstructions are at least 5 meters away from the launcher. Friendly troops providing security must be protected in a fighting position, behind a solid object, or lying prone with steel helmets facing the firing position. Addi Ad diti ti on al Safety Saf ety cons co ns iderat id eratio io ns. ns .
(1) The firer's body must be clear of the front and rear of the weapon while firing. (2) Do not engage hard targets less than 20 meters from the firing position.
2-22
TC 23 23-2
(3) Ear plugs must be worn by the firer as well as other troops in the immediate area. (4) The firer should exercise care when firing the launcher near bushes and trees. Rocket impact with a heavy branch may detonate the rocket warhead. (5) Targets at ranges greater than 200 meters should not be engaged from the prone firing position. The launcher elevation could cause exhaust gases and material to deflect from the ground and injure the gunner.

Section I. FIRING POSITIONS
4-1. GENERAL
The The M20 M202Al rock ocket lau launche cher is fire ired on the righ ight sh shou ould lde er in the stan stand ding ing, kneeling, or prone position. These positions will enable the gunner to fire from any cover on the battlefield. Each position has several factors which facilitate a steady hold, and is representative of how the weapon should be fired in training and in combat. The exact position may vary slightly to conform to the configuration of the gunner's body or the location of the target in relation to his firing position. Y ou must must insure that the position selected is stable, s table, comfortable, comfortable, and most suitable for engaging the target. Regardless of the position used, keep the launcher pointed toward the target with the muzzle end up. A modified sitting position may may have to to be used in a fighting position or on an AP C. These These are discussed later in this chapter. 4-2. STANDING.
a. The first firing position to be discussed is the standing unsupported position (fig 4-1). This position is very similar to the standing position when firing a rifle. To get into this position, face the target and execute a half right face. Spread the feet a comfortable distance apart, and place the weapon on the right shoulder. The body should be well balanced with the hips level. The left hand should be placed on the front cover handle or under the trigger handle assembly of the launcher. The right shoulder should be placed against the rear cover and launcher for stability. The left hand is used to further steady the weapon by grasping the front cover handle and applying a steady rearward pressure.
4-1
TC 23 23-2 Figure 4-1. 4-1. Standing Standing Unsupport ed Position.
b. The standing supported position is designed to make use of any cover the gunner might find and to aid in stabilizing the weapon for more accurate firing. The type of support that will be most commonly found on the battlefield will either be vertical (a tree or high wall) or horizontal (a berm, fallen tree, fence, or a partially fallen wall). (1) To use a tree or high wall for support the gunner would use the position shown in figure 4-2. His left shoulder, forearm, thigh, and knee should rest against the tree or wall. His left knee is flexed and the right leg straight. The gunner should not bring the front of the launcher too close to the support or his sight will be blocked. When using this position the gunner is highly vulnerable to fire from his right side. It should not be used unless the target cannot be seen from the kneeling position.

TC 23 23-2 Figure 4-2. 4-2. Standing Standing Supported Posit ion.
4-3
TC 23 23-2
(2) The gunner may choose to fire over his cover in the standing position. A great deal of support can be obtained from a fallen tree, berm, fence, or partially fallen wall. To fire over his cover the gunner would use the position as shown in figure 4-3. His left hand would be on the handle on the front dust cover with only his index finger through the hole in the handle. The remaining fingers should form a fist and the bottom of the fist should rest on the cover. His feet would be spread a comfortable distance apart. The gunner elevates or depresses the weapon by either increasing or decreasing the distance between his legs.

TC 23 23-2 Figure 4-3. Standing Supported Position (Over Cover).
4-3. KNEELING.
a. The kneeling supported position is similar to the kneeling unsupported position for firing the rifle (fig 4-4). Kneel on the right knee with the right thigh at a 90 degree angle with the line of aim and sit back on the right heel, shifting the weight forward to a comfortable position. As viewed from the front, the lower left leg is vertical. vertical. P lace the launcher on the right shoulder, keeping the rear cover forward of the right shoulder. Rest the upper left arm forward of the left knee, with the the left hand on the front cover handle. P lace the right arm against the side, right hand on the trigger assembly. This This posi osition is more ore su suit itab ablle for engagin aging g stat statio ion nary ary targ argets. To engage moving targets, the gunner should straighten his body and remove his elbow from his knee to aid in tracking the target.

TC 23 23-2 Figure 4-4. 4-4. Kneeling Kneeling Unsuppo rted Positi on.
b. The kneeling supported position can be used to fire around or over the gunner's cover. (1) To fire around the cover the gunner would use the position shown in figure 4-5. He would lean his left shoulder, upper arm, and thigh against the support. He should sit back on his right heel. The left elbow should rest on the upper portion of the left leg, near the knee. The left hand can be moved to support underneath the right hand for long-range targets. The gunner should not bring the front of the launcher too close to the support or his sight will be blocked.

Thi This pos posit itio ion n (fig (fig 4-7) -7) is the most ost stab stable le of the three posit ositio ion ns; howe owever, its its use use is limited to a maximum range of 200 meters. (To engage targets beyond this range requires elevating the front of the launcher which may cause injury from the backblast.) To get into this position, lie down at an angle of not less than 45 degrees to the line of fire in order to keep clear of the backblast area. Your back should be straight and the right leg directly on a line running through the right hip and right shoulder (if possible). possible). P osition osition your your elbows well under the launcher in a comfortable comfortable position. Y ou must must insure insure your legs do not extend extend into the the backblast backblast area. The front dust cover or left wrist can rest on the ground for support. This position is very difficult for some gunners to attain. One or two sandbags under the upper arm or forearm may help, but this procedure is time-consuming and therefore impractical on the battlefield. This position should not be used unless it is absolutely absolutely necessary.

Section Secti on II. EMPLOYMEN EMPLOYMENT T 4-5. INTRODUCTION
The The M20 M202Al rock ocket lau launche cher can can be used sed in both oth an off offensiv sive and and defensiv sive role ole because it is lightweight, has an extended range, and has a minimal maintenance requirement. Due to the weapon's accuracy and the trajectory of the rocket, it can get into areas and enclosures which other weapons cannot enter. It can produce personnel casualties in bunkers, buildings, and covered or open foxholes, as well as damage unarmored vehicles and destroy combustible supplies, ammunition, and materiel. The M202Al rocket launcher produces a psychological effect--the brilliant splash of the bursting warhead makes it an excellent weapon to to suppress RP R P G and Sagger S agger miss issile ile firing sites and when fired near armored vehicles, will normally make the crew button-up. 4-6. GENERAL GENERAL EMPLOYMENT.
The The M20 M202Al rock ocket lau launche cher may be employ loyed like ike oth other dire irect fire weapon apons s wi with the assault element or with a supporting element as a supporting or covering weapon. The M74 rocket is normally employed by infantry elements in the assault for the same purpose as flamethrowers; however, targets can be engaged at a greater range and with greater accuracy with this weapon than with
4-9
TC 23 23-2 the portable flamethrowers. Thus, the M202Al gunner is less vulnerable to enemy fire than flamethrower operators. a. The decision to use this weapon in combat is based upon its availability, the availability of ammunition, and its relative contribution toward mission accomplishment. W14 planning the attack, the company commander and leaders consider the use of the M202Al rocket launcher as part of their plan for fire support. Defensively, the weapon can be used in the coordinated plan for fires and in support of the counterattack. The M202A1 can be employed on likely avenues of approach against enemy over watch positions, to cover dead space, or to set disabled vehicles aflame. Because of its range, lethality, and psychological pa the M202Al should routinely be employed in defensive situations and given specific targets or target areas that are incorporated into the platoon's final protective fires. b. The M202AI can be employ at night using artificial illumination from the M203 grenade launcher, mortars, artillery, or field expedients. In the absence of illumination or if the available light is poor, it is difficult to distinguish the sight reticle. For this reason gunners must observe where rounds impact and shift to the target. If the gunner sees the first round impact through the sight, the burst-on -target technique can be employed using the light produced by the first round. Initial rounds can be fired at targets by using radar sightings, unattended ground sensors, directions from LP/OPs, muzzle ashes, noises, or reflections of light. Adjustment should again be accomplished using the illumination produced by the first round. Consideration should be given to disclosing friendly positions prior to firing at night. c. The M202Al rocket launcher can be employed against disabled armored vehicles, dismounted troops, crew-served or individual weapons positions, wooded areas, fortified positions, or built-up areas. The M202Al is a particularly effective counter suppression weapon when when employed employed against enemy enemy RP RP Gs and and machineguns. machineguns. d. When contemplating employment of the M202A1, Consideration must be given to the smoke which will be produced. Firing the M202A1 close to your defensive position can start fires and the smoke can obscure your vision and aid the enemy. 4-7. FIRING FROM FIGHTING POSITIONS.
a. The M202A1 may be fired from a fighting position (fig 4-8), but special attention must be given to the backblast area. A fighting
4-10
TC 23 23-2 position generally limits the maximum range of the M202A1 to 200 meters, as targets in excess of this range require the muzzle of the launcher to be elevated to aim and fire the weapon. Elevating the muzzle of the launcher directs the backblast into the fighting position, creating the possibility of injury to personnel in the position. Overhead cover on the fighting position will not affect the maximum engagement range as long as the rocket will clear the overhead cover and the backblast area is clear. To engage longrange targets, the gunner must sit on the back edge of the position, firing over the front berm, or he may kneel behind an adjacent berm. Special berms may be constructed. Figure 4-8 4-8.. Firin Firin g fro m a Fighting Position.
b. The M202Al should be positioned so that its backblast will not interfere with nearby friendly positions. In no situation should friendly positions be located within the weapon's 15-meter danger
4-11
TC 23 23-2 zone. If possible, position the M202Al so that no friendly position is within the 25-meter area between the outside edges of the danger and caution zone. If this is not possible, insure that positions within the caution zone are covered and the soldier is protected from flying debris. c. A field expedient method of aiming and firing at preselected probable targets can be constructed for the most important probable target areas in both sectors. To construct the field expedient, six stakes (2-3 feet long) and some wire or rope are required. Figure 4-10 shows the construction. Figure 4-10. Field Expedient Aiming Method.
(1) The rear stakes are driven in first. They should be at least 6 inches into solid ground and perpendicular to the target. The cross member is lashed to the target side of the rear stakes; it should not be too high. (2) The front right stake is positioned next. Its position should be marked by an assistant as the gunner sights on his target. When the weapon is aimed at the target, this stake must be flush against the right side of the launcher and positioned between the front dust cover and the trigger mechanism. When the gunner is aiming, the rear of the weapon should be on the rear stakes. The bridge on the rear dust cover should rest on the rear cross member with the rear dust cover itself flush on the cross member. The right
4-12
TC 23 23-2 side of the launcher should be up against the right rear stake. (3) The left front stake and front cross member are added last. To obtain the proper elevation the front cross member must be lashed at the proper height. This height should be marked by an assistant, as in 4-7c(2) above, while the gunner is aiming. (4) The gunner may fire the launcher by placing it in the field expedient, pushing it up against the right posts, and squeezing squeezing the trigger. 4-8. FIRING FROM FROM AN A N APC.
The The M20 M202Al can can be fired from an APC. Firi Firing from the ope open car cargo hatch atch requires close coordination with all squad members to insure the backblast area is clear. Additionally, the gunner's distance of traverse is limited as the muzzle and rear of the launcher must be outside of the open cargo hatch. EXTREME CAUTION MUST BE USED TO INSURE THAT THE SQUAD MEMBERS INSIDE THE APC ARE NOT INJURED BY THE MUZZLE MUZZLE OR BACKB BA CKBLA LAST, ST, EAR PLUGS MUST BE WORN BY ALL PERSONNEL . If the situation permits, the gunner should sit sit on top top of the APC AP C to fire the the launcher (fig 4-11). 4-11). This This will provide a stable firing position while providing greater flexibility in engaging targets. Caution must be exercised to insure the backblast is clear and ear plugs should be worn. In this vehicular firing position the gunner may fire from either side of the hatch. The driver and caliber.50 machinegunner should button up when the M202Al is fired to the front. The gunner sits on the open cargo hatch. His outside leg (away from the cargo hatch opening) is bent, foot resting to the side of the cargo hatch. His inside leg is extended, foot resting on the front edge of the cargo hatch opening. Support for the launcher is gained by resting the right, or left, forearm on the outside knee. The left hand is placed under the right for additional support support..

4-9. COMBAT IN CITIES.
The The M20 M202Al is an an extremely effecti ctive weapon apon for com combat in cit cities or built ilt up areas. Flames can be delivered on distant targets through windows, doorways, or other holes in the structures with pinpoint accuracy. The detonation of rockets within a structure will create panic and confusion among the enemy occupying the structure. The launcher can be fired from inside a room provided there are no vertical surfaces within 5 meters of the rear of the launcher and the room has another opening to prevent the creation of overpressures. The backblast area must be clear of personnel, debris, and other items and ear plugs must be worn by all personnel in the room.

d. The training program is based on performance-oriented training. Time devote oted to con conference, ce, explan lanati ation, on, and and demonst onstrratio ation n has been minimized. The soldier will learn by doing rather than by listening and watching. Emphasis should be on the small group, hands-on-method of achieving the training objectives. Soldiers
B-10
TC 23 23-2 should practice the actions in the training objectives until they become proficient. When the soldier appears proficient, he should be tested by a noncommissioned officer on a pass/fail or GOINO GO basis. The evaluation tests in the proficiency examination in section II of this appendix may be used for this purpose. If the soldier fails an evaluation test, he should continue to practice and be retested. Those soldiers who have passed the evaluation tests may be used to assist in the training/evaluation of the soldiers experiencing difficulty. difficulty. The recommended recommended soldier/instructor soldier/instructor ratio ratio is 4:1. e. The training program, as written, is compressed to minimum time. When scheduled, consideration must be given to poor weather, training equipment availability, and soldier/instructor ratio greater than 4:1. Any of these conditions will dictate additional time. Recommend normal scheduling of 7 hours. f. The training program should be conducted quarterly with instructional firing accomplished annually. This is necessary since the rocket launcher, M202Al, is issued under the arms room concept and is not assigned a dedicated gunner. As a minimum, it is recommended that the platoon leader, all noncommissionedofficer leaders in the platoon, and one soldier per squad be proficient with the M202Al. g. Training aids and equipment. The actual rocket launcher, M202Al, is considered to be the best training aid available for conducting training on this weapon. Whenever possible, the launcher should be used. Additionally, other training aids may be constructed using the photographs and diagrams contained within this training circular. These training aids should not limit the instructor's imagination nor replace any other training aids which may be available or listed in training aids catalogs. Wherever possible, possible, local Trai T rainin ning g Aids Serv S ervice ice Offices Offices (TASOS (TAS OS)) should be utilized to obtain desired training aids and devices. These TASOs will loan or fabricate the required aids and devices. The following aids and equipment are recommended. (1) Rocket launcher, M202Al-one per two soldiers. (2) Chart depicting sight reticle--one each. (3) Plas P lastic tic reflecting reflecting sight meter meter reticle-one reticle-one per soldier. soldier. (4) Silhouette sheet depicting targets-one per soldier.

(2) Personnel. Personnel. One O ne instructor instructor per four soldiers. soldiers. Should S hould more more than four soldiers be taught by an instructor, the time to conduct the training program will be increased. A trained safety officer/noncommissioned officer must be present during all firing. i. Ammunition. Four 66-mm M74 rockets per soldier. One 66-mm M74 rocket clip for use in the introduction portion of the program to give the soldiers a demonstration of the capability and potential of the rocket launcher. j. For add additional onal inf inform ormatio ation n on how to con conduct a train aining ing progr ogram, see see FM 21-6, How to to Prepare P repare and Conduct Military Military Training. FM F M 21-6 provides provides detailed guidance on the preparation of lesson plans.
B-12
TC 23 23-2 NOTES:
1. Range should be constructed on a generally flat, open piece of terrain out to the maximum range of the weapon with at least 10 meters between firing points. 2. Targets can be salvage vehicles, fabricated bunkers, and/or dirt-filled 55-gallon drums. drums. 3. If available, an M72A2 LAW range may be used to accommodate the firing of the M202Al by increasing the width of the danger and caution zones. The backblast area is 40 meters long and 38 meters at the base.

1. Although specific targets are cited in the table, the local availability of targets is a consideration. Therefore, any meaningful and realistic target may be constructed or used. Targets should be placed at the ranges specified. 2. At present there is no subcaliber device for the M202Al. A program to develop a subcaliber device is underway, but due to the limitations of the device, the date of fielding a subcaliber device is unknown. Until a subcaliber device is fielded, each soldier should fire four 66-mm M74 rockets as shown in the firing table.
