CHAPTER 6


TRAINING EQUIPMENT
AND INSTRUCTOR TRAINING

Training equipment provides units with a low-cost means to develop and maintain gunner skills. Instructors must know the Dragon and training equipment to train gunners. This chapter describes the training equipment for the Dragon and provides a program to train instructors on training equipment use.

Section I. GUNNERY TRAINING EQUIPMENT

The training equipment is used with the tactical tracker and other tactical hardware for realism. Gunnery training equipment is issued to units equipped with authorized tactical trackers. Units are responsible for proper maintenance of assigned training equipment. (See Figure 6-1.)

6-1. LAUNCH EFFECTS TRAINER


The LET simulates the tactical round in appearance, weight, center of gravity, and some launch transient characteristics (Figure 6-2). The LET uses the M64 blank rifle grenade cartridge to simulate the noise, recoil, and weight shift from the gunner's shoulder and the time delay between trigger squeeze and launch.

NOTE: The weight shift of the Dragon round is more than the LET. If the gunner has adopted the correct holding technique, the weight shift will not be noticed.

a. The LET does not simulate Dragon launch. During the launch, there is a temporary obscuration of the gunner's view. The Dragon LET does not simulate the heat, flame, and dust of the launch or the appearance of the missile to block the gunner's view.

b. The LET consists of a bipod, launcher, tracker support assembly, and LET subassembly. Attached to the launcher are the forward and rear shock absorbers and the sling. The bipod assembly includes a tube and yoke assembly with a brace latch. A modified tactical version of the tracker support assembly is employed for multiple use, which supports and secures the tactical tracker in place. It also provides the electrical interface between the tracker and LET (Figure 6-2).

c. The LET allows a gunner to use any firing position shown in Figure 6-3. One set of training equipment ideally should not be closer than 6 meters to another set. The LET can be fired by itself or with the monitoring set, which evaluates gunner performance data and displays the results.

d. The LET shipping and storage container (Figure 6-4) is used when the LET is transported or stored. The cleaning brush is used to clean the LET and has a pushrod for resetting the weight.

6-2. AN/TSQ-1 MONITORING SET


The monitoring set monitors and evaluates the gunner's tracking performance (Figure 6-5). The set is powered by self-contained, rechargeable batteries.

a. The monitoring set case assembly consists of two sections. The top section of the monitoring set provides storage for the five electrical cables and operator's manual. The bottom section (base) contains the monitor control and display panel, electronic assemblies, humidity indicator, battery packs, and battery charger.

(1) The monitoring set battery packs consist of four 10-VDC batteries, which provide power for the regulated plus or minus 13-VDC needed to operate the monitor and tracker. The battery packs are rechargeable by using any of the following power sources: 18-VDC to 30-VDC, 190-VAC to 230-VAC (50 to 100 Hz), and 105-VAC to 130-VAC (50 to 400 Hz).

(2) The control panel has a mounting for the monitoring set controls, indicators, lights, and connectors. (See Figure 6-6.) The J connectors are on the control panel to provide connection points.

(a) The J1 LET connector, used with the trainer, provides for input stimuli to the monitoring set circuits.

(b) The J2 recorder connector is used to supply input signals to a chart recorder.

(c) The J3 MON TEST SET connector provides test points for use during maintenance and calibration of the monitoring set.

(d) POWER INPUT connector is used during battery charging.

b. The monitoring set provides two scoring functions. One function indicates the probability of the missile hitting or missing the target, and the direction and range at which the maximum aiming deviation was exceeded, resulting in the monitoring set registering a MISS. The other function indicates numerically the gunner's ability to maintain a steady aim point.

(1) HIT or MISS indications are not directly related to numerical scores. The monitoring set can register a high score with a MISS indication, or a low score with a HIT indication. This depends on whether the gunner's aiming deviations exceeded the maximum aiming deviation limits.

(2) The gunner's aiming deviation shows his aim point with respect to the desired target aim point (Figure 6-7).

6-3. M89 INFRARED TRANSMITTING SET


The infrared transmitting set is vehicle-mounted and is used with the LET or LES and monitoring set (Figure 6-8).

a. The target set can be used in any simulated tactical operation. It operates in all weather conditions in which the gunner can track the target. The target set is used for gunner indoctrination, tracking instruction, practice, and qualification.

b. The infrared transmitter operates with any 24-VDC 40-amp system. It can be mounted on the M113 APC, M151 1/4-ton truck, HMMWV 1 1/4-ton truck, M60A1 tank, or M561 Gamma Goat. The target source generates an infrared beam that simulates an in-flight missile. As the gunner tracks the target board, the infrared receiver in the tracker picks up the beam. This information is processed by the monitoring set to score the gunner. The components of the infrared transmitting set areas follows:

WARNING: During operation, do not look into the target source lamp when in the danger zone. (See Figure 6-9.) Do not look at the target source through vehicle mirrors or any other reflective surface. Serious eye damage could result, requiring immediate medical attention. Also, do not look into the infrared lamp (target source) when within 3 meters of the target source.

(1) Target source. The target source operates at training frequency (5 KHz) and simulates the missile flare. Personnel must not enter the danger zone while the target source is operating (Figure 6-9).

(2) Target source support. The target source support is an aluminum, rectangular box that houses the target source, provides a mounting surface for the target board, provides cable storage, and mounts to the pedestal.

(3) Target board assembly. The target board assembly is an aluminum alloy board with a red cross painted on a white background. It is used as the aiming point for the gunner.

(4) Power supply modulator. The power supply modulator provides power to and controls the operation of the target source.

(5) Connecting cables. The target source cable carries starting and drive currents from the PSM to the target source. The power supply/modulator battery cable connects the PSM with the vehicle electrical system.

(6) Target mounting kit. The target mounting kit consists of a pedestal, universal adapter plate, four cargo slings, and related hardware. It serves as a base for the infrared transmitter.

6-4. FIELD HANDLING TRAINER


The FHT is a spent tactical round refurbished to simulate the tactical round in weight and shape. It provides a gunner with practical experience in tactical deployment, handling, aiming, and tracking. An FHT consists of the following modifications:

a. The remains of the rear shock absorber are removed from the spent round, and a new rear shock absorber is bonded in place. The tracker electrical connector is removed. A weight simulator, M8E2, is secured in the spent round with three screws, and a forward shock absorber is installed on the round.

b. The launcher color band and warhead color band are painted over. The propulsion color band is changed to a 1-inch (2.54 centimeters) bronze band. The word EMPTY is painted in 1-inch (2.54 centimeters) white letters on the side of the launcher.

6-5. LAUNCH ENVIRONMENT SIMULATOR


The LES is about the same size, shape, and weight as the tactical round and simulates its launch environment. (See Figure 6-10.) The LES uses a combination of MAPP gas, oxygen, and biodegradable end caps to produce a realistic simulation of the Dragon launch. The LES launcher is shipped with a blast deflector, which should be installed on the rear of the launcher. The blast deflector causes the rear of the launcher to rise during the firing sequence. This simulates the shoulder weight loss experienced when launching a missile.

a. The LES is used with the Dragon trackers, monitoring set, and infrared transmitting set, This gives an accurate evaluation of gunner performance during training exercises.

b. An electrical pulse, generated by the Dragon tracker's firing mechanism, activates the LES control box electronics. This supplies current to the glow plug inside the launcher. The glow plug ignites the MAPP and oxygen gas mixture. An electronic time delay is incorporated in the LES control box electronics to simulate the delay between trigger squeeze and launch.

c. The LES control box (Figure 6-10) case assembly consists of two sections. The top section (cover) provides hose and cable storage space. The bottom section (base) contains the LES control panel, electronics assembly, battery pack, and MAPP gas and oxygen bottles and their respective regulators.

Section II. INSTRUCTOR TRAINING

WARNING: Explosive gases are being used. Ensure there are no open flames, sparks, or sources of ignition from the operating area.

8. Have the loader conduct a test fire and notify the gunner that the LES launcher is ready.

TRAINING NOTE: Ambient temperature and humidity affect LES firing performances. Optimum firing results in the end cap being fragmented, thereby dispersing flour. Set the regulators initially at 16 psi MAPP and 46 psi oxygen, and perform a test fire. If the end caps are shattered, the mixture is correct. If the end caps are expelled intact and an orange flame is observed (indicating fuel rich condition), reduce the MAPP gas setting while holding the oxygen setting constant to a minimum of 14 psi. If still rich, increase the oxygen pressure to a maximum of 50 psi. To reset regulators to a lower pressure, turn the regulator control full counter-clockwise, remove both end caps, depress the FILL switch, install end caps, adjust regulators to new pressure, and proceed to STEP 5.

9. Have the gunner track and engage targets.

NOTE: To repeat the firing exercise, have the loader install new end caps.

WARNING: Before subsequent firings, ensure there is no glowing residue from end caps near either end of the LES launcher tube.

10. Have the gunner perform immediate-action procedures. If a NO FIRE occurs (gases fail to ignite) apply immediate action as follows:

a. Waits five seconds and squeezes the firing mechanism again.

b. If the LES does not fire after the second attempt, the instructor immediately sets the ARM-SAFE switch on the control box to SAFE.

(1) Sets PWR ON-OFF-CHARGE switch to OFF.

WARNING: Do not allow any part of the body to extend in front of or behind the LES launcher while performing the following steps.

(2) Removes both end caps from the launcher and allows a minimum of two minutes for the gases to vent.

(3) Unlatches and reseats the tracker.

(4) After two minutes, reinstalls both end caps.

(5) Sets PWR ON-OFF-CHARGE switch to ON.

(6) Performs BATTERY and GLOW PLUG tests. (See Training Objective 6, Conduct a LES System Checkout.) If the BATTERY TEST indicator does not illuminate, see Table 6-1. If the GLOW PLUG circuit test does not illuminate, set the GLOW PLUG select switch to the alternate circuit and retest. If the light still fails to illuminate, see Table 6-1. Check the oxygen pressure.

(7) If all of the above indications are satisfactory, proceeds to STEP 5 of Table 6-1.

(8) If immediate action does not correct misfire, returns the LES to TSC for maintenance.

TRAINING NOTE: Table 6-1 lists the items most likely to fail during operation. Most failures cannot be corrected by the instructor. Replace the launcher or control box and notify the TSC or organizational maintenance of the failure when the equipment is turned in.

If the target range is changed more than one range segment, the monitoring set must be realigned IAW the equipment alignment check.

3. Operation of the training equipment for day and night training exercises is the same except for the sight pictures.

PERFORMANCE MEASURES:

1. Select a site.

NOTE: Before operating the training equipment, all personnel must refer to local regulations and SOPs for general safety precautions.

WARNING: The monitoring set operator, gunner, and loader must wear ear protection.

2. Prepare the monitoring set. Before conducting a training exercise, align the monitoring set.

3. Operate the infrared transmitter.

4. Prepare the LET or LES for operation. Ensure that the loader and gunner prepare the LET or LES for operation IAW Training Objective 5, Prepare/Operate a LET, or Training Objective 7, Prepare/Operate a LES; and the appropriate TM.

d. Instruct the gunner to fire when the loader gives an UP signal.

e. Have the monitoring set operator observe the monitoring set control panel after the gunner fires each round and during each tracking run for moving targets. The indicators show how well the gunner performed during each run.

6. Prepare and use the gunner's scorecard.

LINE 1. Identifies the gunner. Fill in all the blocks.

LINE 2. Circle weather condition. Place a check on the appropriate tracker used. Indicate which MOPP level is used (0 through 4). Mark obscuration if any type is used (smoke, dust, and so forth).

LINE 3. Check which type of position is used and if the fire table is for instruction or qualification.

7. Follow the examples on how to complete the scorecard (Figure 6-17 and Figure 6-18). Use DA Form 4242-R, Dragon Gunnery Scorecard, to score and critique the gunner. The blank, reproducible form is at the back of this manual. Gunner must fire both a sitting and standing supported table to achieve a qualification score (Appendix C).

8. Score and critique the gunner. See the following examples for use of the scorecard (Figure 6-17 and Figure 6-18).

EXAMPLE

The following is an example scoring exercise at 500 meters.

For a HIT, see STEPS 1 through 2.

For a MISS, see STEPS 3 through 8.

Indicate the vehicle direction by L-R or R-L (left to right or right to left) or by drawing an arrowing pointing the way the vehicle was traveling.

STEP 1. The HIT indicator is lit, and an X is recorded in the hit column. The gunner's firing position is recorded. (See Figure 6-17.)

STEP 2. Check the score on the TRACKER INDICATOR SCORE meter.

a. Read the vertical (up and down) score by observing the position of the vertical score bar (the bar that runs across the meter) and by reading the number value directly underneath it. That number is written in the VERT column on the scorecard. (The example score is 85.)

b. Read the horizontal (left and right) score by observing the position of the horizontal score bar (the bar that runs up and down) and by reading the number value directly underneath it. That number is written in the HORZ column on the scorecard. (The example score is 85.)

STEP 3. The MISS indicator is on, and an X is recorded in the MISS column. (See Figure 6-18.)

a. The gunner's score is recorded on the scorecard using the TRACKER INDICATOR SCORE meter. (See STEP 2.) (The example score is 75 VERT and 85 HORT.)

b. The gunner's firing position is recorded.

STEP 4. At the end of the run (500 meters, simulated), the monitoring set indicates a MISS, but OFF TARGET indicators are not lit. This means that the gunner was on target at 500 meters but off target at some other range. The TARGET RANGE knob is rotated counterclockwise to 4.

STEP 5. At 400 meters, the MISS indicator is still lit, but the UP and R OFF TARGET indicators are lit. This indicates the gunner was off-target, too high, and to the right of the target at that range. A 4 is written in the UP and RIGHT columns of the scorecard (Figure 6-18). The TARGET RANGE knob is rotated counterclockwise to 3.

STEP 6. At 300 meters, the MISS indicator is still lit, but only the R OFF TARGET indicator is lit. This indicates the gunner was off the target to the right of the target at that range. A 3 is written in the RIGHT column of the scorecard (Figure 6-18). The TARGET RANGE knob is rotated counterclockwise to 2.

STEP 7. At 200 meters, the MISS indicator is still lit, but only the L OFF TARGET indicator is lit. This indicates the gunner was off the target to the left at that range. A 2 is written in the LEFT column of the scorecard (Figure 6-18). The TARGET RANGE knob is rotated counterclockwise to 1.

STEP 8. At 100 meters the MISS indicator is still lit, but OFF TARGET indicators are not lit. This indicates the gunner was on target at that range. Nothing is recorded on the scorecard for this range.
