Section II. SYSTEM DESCRIPTION

1.5 GENERAL

a. SRAW Predator. The SRAW Predator MK 40, Mod 0, (DODIC PL61), shown in Figure 1-1, is a man-portable, fire-and-forget assault weapon designed to defeat advanced armor threats. The weapon is shoulder fired and can be carried by an individual Marine. Once the weapon has been fired, it cannot be reloaded and the launcher should be destroyed. The tactical weapon consists of a launcher and missile. After launch, the missile flies a trajectory about 2.75 meters (9 feet) above the gunner’s line-of-sight (LOS). This enables the missile to attack the vulnerable top of the target by over-flying and detonating an Explosively Formed Penetrator (EFP) warhead down into the target. The missile senses the magnetic signature of the vehicle (designed for main battle tanks) using a magnetometer, and the leading/trailing edges of the vehicle using a laser range finder. The target detection system

TM 10687A-OR/C fires the warhead at a point determined to produce a lethal, top-down blast into the target. Table 1-1 lists the physical characteristics of the weapon.

NOTE

The SRAW Predator and SRAW MPV can be distinguished by the bandings on the launch tube. SRAW Predator has three bands: black signifying anti-armor, yellow signifying high explosive, and brown signifying low explosive. SRAW MPV has two bands: yellow and brown.

b. SRAW MPV. The SRAW MPV MK 41, Mod 0, (DODIC PM78), shown in Figure 1-2, is a man-portable, fire-and-forget assault weapon designed to defeat fortified positions and light armor threats. The weapon is shoulder fired and can be carried by an individual Marine. Once the weapon has been fired, it cannot be reloaded and the launcher should be destroyed. The tactical weapon consists of a launcher and missile. After launch, the missile flies a flat trajectory along the gunner’s line of sight (LOS). Upon impact with the target, the fuse senses a hard or soft target. If the target is a “hard” target (e.g., a brick wall), the fuse detonates on impact. If the target is a “soft” target (e.g., sandbags), the fuse will delay detonation to further penetrate the target. Table 1-2 lists the physical characteristics of the weapon.

OPERATING INSTRUCTIONS

Section I. CONTROLS AND INDICATORS

2.1 TRIGGER HOUSING ASSEMBLY The trigger housing assembly, as shown in Figure 2-1, is located on the right side of the launcher (when looking forward). The gunner’s primary controls are the battery activate plunger, fire bar, fire bar cover, and battery activate indicator.

a. Battery Activate Plunger. The battery activate plunger (1)

is a thumb-operated plunger that activates the missile’s autopilot battery allowing, a 2-12 second tracking window. Once the battery activate plunger is pressed and held, the gunner must press the fire bar within 2-12 seconds or the weapon’s performance becomes severely degraded.

2-1

TM 10687A-OR/C

CAUTION

If the target is not tracked for at least 2 seconds and the weapon is not fired within 12 seconds of battery activation, the weapon’s performance becomes severely degraded.

b. Fire Bar. The fire bar (2) is a lever device designed to be

pushed downward by the fingertips. Once the battery activate plunger is pressed and held, the fire bar mechanism is unlocked. Pressing the fire bar activates the ordnance battery and commands missile launch.

c. Fire Bar Cover. The fire bar cover (3) is a hinged

protective device that helps prevent damage to the fire bar mechanism. A notch in the end of the cover slips behind the head of the battery activate plunger to prevent accidental activation. The notch is fitted with a spring-clip that secures it to the battery activate plunger. The cover is lifted by the gunner’s thumb and fingers to gain access to the battery activate plunger and the fire bar.

d. Battery Activate Indicator. The battery activate indicator

(4) is a window in the link bar of the trigger housing assembly. A green field in the window indicates a non-activated autopilot battery condition; a battery with a line through it indicates the autopilot battery has been activated, as shown in Figure 2-2. The battery activate

2.2 TELESCOPE ASSEMBLY The telescope assembly, Figure 2-3, provides a 2.5x magnification, 8-degree field of view of the target area. The telescope assembly is equipped with a day sight, eyecup, and night sight mounting rail.

a. Day Sight. The day sight (1) contains a series of lenses and mirrors. Between two of the lenses is a reticle used for sighting the target. Although an internal filter reduces the chances of eye damage caused by enemy laser transmitters, laser eye goggles must be worn when under laser threat conditions. During transport, the eyepiece is stowed down against the launch tube. When ready, the gunner moves the eyepiece up and out from the stowed position to the first detent for missile firing. The second detent is used for boresighting the night sight.

b. Eyecup. The eyecup (2) is soft and conforms to the

gunner’s eye.

2-5

TM 10687A-OR/C

c. Night Sight Mounting Rail. The night sight mounting rail (3) accepts the AN/PVS-17C night sight, as shown in Figure 2-4. The mounting rail is a standard design capable of receiving various night vision devices.

d. Night Sight. The AN/PVS-17C provides 2.5X magnification.

Section II. FUNCTIONAL DESCRIPTION OF THE SRAW

To properly destroy targets with the SRAW, five major functions must occur; target tracking, missile launch, missile flight, arming, and target detection/destruction.

2.3 TARGET TRACKING

When the gunner presses and holds the battery activate plunger, the missile autopilot battery is activated and initiates the missile guidance circuitry contained in the autopilot module. While the gunner holds the crosshairs on the target, the autopilot senses and stores acceleration and angular rate data until the fire bar is pressed. (Once the battery activate plunger is pressed and held, the target must be tracked for a minimum of 2 seconds before pressing the fire bar.) The autopilot battery allows for a maximum tracking interval of 12 seconds to ensure a steady, constant track of the target. When the fire bar is pressed, the missile launch sequence is initiated.

2-8

TM 10687A-OR/C

2.4 MISSILE LAUNCH The launch sequence includes initiation of the Round Release Mechanism (RRM), ignition of the launch motor, and ignition of the Jet Reaction Control Assembly (JRCA). When the fire bar is pressed a gas cartridge within the RRM is fired, causing ejection of the aft closure and RRM out of the aft end of the launch tube. The launch motor ignites and burns out before the missile exits from the launch tube. The entire process, from pressing the fire bar to tube exit by the missile, is completed in approximately 0.250 seconds. As the missile moves down the launch tube, the forward closure is pushed away. When the missile clears the launch tube, four spring-loaded, 3-inch fins deploy to stabilize the missile’s flight. The JRCA provides missile steering for the missile flight. 2.5 MISSILE FLIGHT

a. SRAW Predator. After coasting for approximately 5 meters

(16 feet) downrange, the flight grain portion of the rocket motor ignites. The flight grain burns for approximately 1 second and provides sufficient boost for the missile to

2-9

TM 10687A-OR/C

cover the maximum operational range of 600 meters (1,968 feet) in approximately 3 seconds.

The autopilot compensates for moving targets, as shown in Figure 2-5. While the gunner is tracking a moving target, the system calculates the target’s rate of movement. The rate is stored in memory and during missile flight produces steering commands causing the missile to follow the calculated rate of the target. A 7° fixed elevation angle (relative to the gunner’s sight) is held by the missile for about 50 meters (164 feet). The missile then pitches down to a flight level 2.75 meters (9 feet) above the sightline. This elevation is maintained for the remainder of the flight.

2-11

TM 10687A-OR/C

The autopilot compensates for moving targets, as shown in Figure 2-6. While the gunner is tracking a moving target, the system calculates the target’s rate of movement. The rate is stored in memory and during missile flight produces steering commands causing the missile to follow the calculated rate of the target. The missile flies out to the target along the gunner’s line of sight.

TM 10687A-OR/C

2.6 ARMING

To protect the gunner from premature warhead detonation, neither the Safe and Arm (S&A) mechanism of the SRAW Predator nor the fuze of the SRAW MPV will arm the warhead until several events have occurred. The events are as follows:

• The missile has departed the launch tube.

• The flight motor has ignited.

• The missile has sustained a specified acceleration.

The SRAW Predator missile is armed at 17 meters (55 feet).

The SRAW MPV missile is armed at 25 meters (82 feet).

2-13

TM 10687A-OR/C

2.7 TARGET DETECTION/DESTRUCTION

a. SRAW Predator. The Target Detection Device (TDD) for

the SRAW Predator includes a laser transmitter/receiver for target ranging and a magnetometer for sensing the presence of valid targets, as shown in Figure 2-7. The laser system constantly measures changes in range (from the TDD to any surface). A target’s leading edge is detected by a sudden decrease in laser range and the target’s trailing edge is detected by a sudden increase in laser range. The missile’s magnetometer senses disturbances in the local magnetic field. When the missile approaches a target with enough magnetic disturbance (designed for main battle tanks), the magnetometer informs the TDD microprocessor of a valid target detection. Combined with laser ranging and magnetic sensing, the TDD ensures the warhead is directly over the target’s vulnerable turret, and then delivers a warhead fire command, causing the Explosively Formed Penetrator (EFP) to form and penetrate down through the turret.

b. SRAW MPV. The SRAW MPV has a dual mode fuze

that automatically discriminates between hard and soft targets. Upon hard target impact (e.g., brick wall), the fuze functions in the super quick mode, causing the warhead to detonate immediately. Upon soft target impact (e.g., sandbag bunker), the fuze functions in the delay mode, allowing the warhead to penetrate the target prior to detonation.

Section III. OPERATION, NORMAL CONDITIONS

2.8 PREPARATION This section provides instruction on using the SRAW under normal conditions. To prepare for a mission with the weapon, perform the following actions:

When transporting an unpacked SRAW in a vehicle, the gunner must ensure the weapon is not standing with its forward end down. Failure to comply with this caution may cause internal damage to the weapon.

CAUTION

a. Remove the weapon from its container as prescribed in Paragraph 3-1.

b. Perform the PMCS inspections as prescribed in Table 3-3.

c. Adjust the sling for desired length.

d. Ensure the day sight is stowed.

2-17

TM 10687A-OR/C

2.9 CARRYING TECHNIQUES

There are three basic methods of carrying the SRAW weapon: the hand carry, the sling carry, and the back carry. Tactical situation should be considered when choosing a carrying technique. The back carry should not be employed when on icy or rocky terrain. During transportation of the SRAW the forward end of the weapon should be pointed up.

a. Hand Carry. The hand carry is

shown in Figure 2-8.

Figure 2-8. Hand Carry.

2-18

TM 10687A-OR/C

CAUTION

When transporting the SRAW using the sling, the gunner must ensure the forward end is not pointed straight down. Failure to comply with this caution may cause internal damage to the weapon.

2.11 FIRING SITE SELECTION

There are six site selection concerns for successful firing of the SRAW and the safety of the gunner and other friendly forces in the area. These concerns are as follows:

• Field of Fire

• Backblast Area

• Enclosure Firing

• Bunker Firing

• Elevation/Depression Firing Limitations

• Cant

a. Field of Fire. The gunner must ensure that the field of fire is completely free of obstructions, as shown in Figure 2-12. Trees, brush, rocks, or buildings blocking the gunner’s line of sight to the target will block the missile’s flight. When employing the SRAW Predator, overhead obstructions such as trees and powerlines 2.75 meters (9 feet) above

2-23

TM 10687A-OR/C

the gunner’s line of sight will also block the missile’s flight. If engaging moving targets, the gunner must ensure there is a sufficient kill window for the missile to reach the target before the target becomes obstructed. The missile will reach a moving target at 200 meters (656 feet) in approximately 1.6 seconds and a moving target at 100 meters (328 feet) in approximately 1.2 seconds. For clean-shot confidence, the gunner should assume a missile flight of 3.0 seconds in all moving target situations.

ENSURE CLEARFIELD OF FIRE

2-24

TM 10687A-OR/C

a. Field of Fire – Continued.

Determination of the kill window must include: – Time to acquire the target with the bare eyes. – Time to align the target in the weapon sight and to make a firm decision to fire. – Time to track – minimum of 2 seconds. – Time for the missile flight.

NOTE

(SRAW PREDATOR ONLY)

Once the SRAW Predator missile is launched, it will engage the first target for which it is designed (main battle tanks and armored vehicles). Destroyed tanks and armored vehicles within the missile’s line of flight may cause the missile to detonate. If destroyed or nondesired targets are in the flight path of the missile, the gunner must move to an alternate firing position or wait until the flight path is clear.

2-25

TM 10687A-OR/C

WARNING

The SRAW backblast is hazardous. The gunner must ensure that no friendly troops are in the backblast area before firing. Failure to comply with this warning may result in severe injury or death.

b. Backblast Area. Ensure there are no friendly forces within 25 meters (82 feet) of the backblast area (Figure 2-13).

e. Elevation/Depression Firing Limitations. The SRAW

can effectively fire at targets up to a maximum of 30 degrees downward or 30 degrees upward from the gunner’s position.

f. Cant. The SRAW can effectively fire up to a maximum

15-degree cant angle.

2.12 FIRING POSITIONS Once the firing site has been selected, the gunner can choose from one of four positions for firing the SRAW. The positions are:

– Standing

– Kneeling

– Sitting

– Prone The surroundings and tactical situation may determine which position to choose. When possible, use standard marksmanship

2-34

TM 10687A-OR/C

principles to employ the position that provides the most stable platform for accurate aiming and firing of the weapon. When using any of the positions, supporting elbows on sandbags, walls, etc., will greatly improve stability and ensure more accurate shots. However, tracking of moving targets is difficult when the elbows are grounded.

a. Standing Firing Position.

The standing position, as shown in Figure 2-18, is suitable when the gunner has most of his body protected with a structure, such as a low brick wall or embankment. It is not recommended to use this position in an open area; to do so would make it difficult to steady the weapon for sighting and increase the gunner’s vulnerability. Figure 2-18. Standing Firing Position.

2-35

TM 10687A-OR/C

b. Kneeling Firing Position. The

kneeling position, as shown in Figure 2-19, is suitable when firing from behind low structures. It offers the advantage of being able to use the knee to steady the weapon while also reducing the gunner’s exposure to enemy fire.

Figure 2-19. Kneeling Firing Position.

2-36

TM 10687A-OR/C

c. Sitting Firing Position. The sitting position offers both a

low profile and maximum support to steady the weapon. Two variations for the sitting position are shown in Figure 2-20.

NOTE

• A click or a snap indicates that the fire bar cover has been released.

• When aiming at the target, do not lead the target. The weapon’s guidance system will compensate for distance and target movement.

2-57

TM 10687A-OR/C

CAUTION

• The gunner must not raise the fire bar cover or press

the battery activate plunger until a positive decision has been made to fire the weapon. If the weapon is not fired within 12 seconds of battery activation, its performance becomes severely degraded.

• Once tracking of the target has begun, it must not be interrupted. If tracking is interrupted or erratic for any reason, a full 2 seconds of steady tracking must be performed prior to pressing the fire bar. Failure to observe this caution may result in degraded missile performance.

(1) Make fire/no-fire decision. (2) Using thumb and fingers of right hand, lift fire bar

cover up and forward to gain access to battery activate plunger and fire bar as shown in Figure 2-32.

(4) Track target for at least 2 seconds, but no more

than 12 seconds.

NOTE Missile launch will occur in less than one-half of one second after fire bar is pressed.

CAUTION

Gunner must ensure aim point is maintained throughout the firing process. Pulling the weapon down while depressing the fire bar could cause the missile to drop below the line of sight causing a misfire.

(5) While maintaining reticle on target, press fire bar.

(6) Remove night sight (if installed).

(7) After weapon has been fired, if possible destroy

launch tube as follows: 2-60

TM 10687A-OR/C

a. Remove sling. It may be kept for other purposes. If destruction is desired, cut sling into pieces so that it is not usable by the enemy.

b. Using a rock, brick, or E-Tool, smash day sight and trigger housing assembly so neither can be used by the enemy.

Destroying the expended SRAW launch tube may be hazardous. The gunner should wear eye protection and gloves when using rock, brick, or E-Tool to destroy weapon. Failure to comply may result in injury.

WARNING

c. Destroy launch tube by running over it with a vehicle. If a vehicle is not available, tube should be destroyed using a large blunt object, such as a rock, brick, or E-Tool.

TM 10687A-OR/C

Section IV. OPERATION, UNUSUAL CONDITIONS

This section addresses two conditions considered unusual or abnormal for the SRAW. These conditions are weapon malfunctions and operation in Nuclear, Biological, or Chemical (NBC) conditions.

2.15 WEAPON MALFUNCTIONS

When the SRAW fails to operate properly, one of three events has occurred: a misfire, a hangfire, or a flight motor failure.

a. Misfire: A misfire is characterized by a failure of any

pre-launch events to occur (i.e., failure of activation of the autopilot battery and/or the ordnance battery).

b. Hangfire: A hangfire is characterized by a failure of the

missile to depart the launch tube after the pre-launch events have occurred.

2-62

TM 10687A-OR/C

Immediate action procedures are the same for both misfires and hangfires and are as follows:

When the SRAW missile fails to launch properly, the weapon is in the hangfire/misfire condition. The gunner must observe proper procedures if a hangfire/misfire condition exists. Failure to observe proper procedures may result in serious injury or death.

WARNING

The gunner must continue to aim the weapon at the target while conducting immediate action procedures. The missile may launch when fire bar is released.

CAUTION

(1) If missile does not launch immediately after pressing fire bar, keep weapon pointed downrange and shout MISFIRE to alert nearby personnel.

2-63

TM 10687A-OR/C

(2) Release fire bar and battery activate plunger.

(3) Press and hold battery activate plunger again, track for at least 2 seconds, and press fire bar again.

(4) If missile still fails to launch, keep weapon aimed at target or downrange for at least 60 seconds.

(5) While keeping weapon aimed downrange and backblast area clear of personnel, unshoulder the weapon and place on the ground with the carrying handle up.

(6) Alert nearby personnel of the misfire condition.

(7) Notify immediate supervisor and/or range safety personnel who, in turn, will contact Explosive Ordnance Disposal (EOD) personnel for disposal.

c. Flight Motor Failure. This condition exists when the missile’s launch motor successfully ignites and the missile is launched out of the tube, but the flight motor fails to ignite when the missile has traveled

2-64

TM 10687A-OR/C

approximately 5 meters (16 feet). When this happens, the missile will fall to the ground after coasting a short distance. The warhead will not be armed and will be a dud. Perform the following procedures in the event of a flight motor failure:

WARNING

(FOR SRAW PREDATOR ONLY)

The SRAW Predator’s Target Detection Device (TDD) contains a Class 3 laser that can continue to transmit if the warhead fails to detonate. Stay at least 5 meters (16 feet) away from a dud missile for at least 5 minutes. Failure to comply with this warning may result in eye injury.

(1) Alert nearby personnel of the dud missile and its location.
