5-12. DAY RECORD FIRE QUALIFICATION STANDARDS
Before firing, each grenadier must know the tasks, the time and ammunition required, the procedures to follow if a stoppage occurs, the penalties for failure to stop firing when commanded or signaled to do so, and the method used for scoring targets.
a. Time and Ammunition. Each grenadier determines the target and its distance before loading any rounds. When the grenadier receives the command to FIRE, the time allotted for that task in Firing Table I begins.
b. Stoppages. The grenadier must apply immediate action procedures if a stoppage occurs. If he can reduce the stoppage, he can continue to fire the course. The trainers allow each grenadier an extra 15 seconds for each application of immediate action.
-
(1) If a stoppage occurs that you cannot reduce by immediate action,
raise your hand and announce "Time."
(2) When you say "Time," the assistant trainer notes the time, ensures that a real stoppage exists, and tries to clear the stoppage. If he clears it, you can complete firing. If he is unable to clear it, the grader will clear it, and you will be allowed 15 seconds for each round remaining to complete firing.
(3) If you made an error that caused the stoppage, you do not receive extra time, and your score consists only of whatever you had earned when the stoppage occurred.
(4) If the grenade launcher must be replaced, you are allotted 10 rounds to zero a new one, then you may repeat the exercise.
(5) If malfunctions prevent you from finishing the exercise in the time allowed, you can finish it in an "alibi run" after all other grenadiers complete firing.
c. Penalties. Five points are deducted from the score of any grenadier who fails to stop firing when the trainer commands or signals to do so. If a grenadier fires at the wrong target, he loses the rounds allotted for the other target, which leaves him only the remainder of his rounds to expend on both targets.
d. Target Scoring. The trainer or assistant trainer records scores on DA Form 2946-R. They determine whether each grenade fired is a hit or miss, then assign 0 points for a miss or 10 points for a hit. Tasks 1 through 3 each consist of two targets, so the total available for each of these tasks is 20 points. The grenadier may select which of the two targets to engage first. If he scores a hit on the first, the trainer permits him to engage the second, and he returns all unexpended rounds to the assistant trainer. Tasks 4 and 5 each consist of firing one target, for a total of 10 points each.
-
(1) Window or door. To score a hit on a window or door, the grenade must
either strike the target or go through the opening in the center of the
target.
(2) Bunker. To score a hit on the bunker the grenade must strike anywhere on the face of the bunker.
(3) Automatic weapon. To score a hit on an automatic weapon, the grenade must strike within 10 meters of the target.
(4) Troops. To score a hit on troops, the grenade must strike within 10 meters of the target.
The grenadier must mount the AN/PVS-4 to the weapon before he zeroes it, and he must do both before he can qualify with the M203 grenade launcher. To mount the scope, he must--
a. Remove the quadrant sight.
b. Position the mounting bracket assembly on the left side of the rifle so that the two clamps project through the opening under the handle. Loosen the wing nuts completely (Figure 5-12).
c. Turn the clamp plates so that the pointed ends are in the UP position and are seated against the handle.
d. Tighten the wing nuts clockwise until the mounting bracket is secure against the weapon.
e. Position the sight in the groove on top of the bracket, and align the threaded hole in the base of the sight mounting adapter with the lever screw assembly. Tighten the screw clockwise firmly to secure the sight to the bracket.
5-14. ZEROING THE AN/PVS-4 TO THE M203
After the nightsight is mounted on the M203, it is zeroed to the M16. This
must be done before the nightsight can be zeroed to the M203. FM 23-9
provides instructions for doing this. Then the M16 is used to zero the
nightsight to the M203. The grenade launcher rounds are fired only to confirm
the zero. To zero the nightsight to the M203--
a. Center the Reticle Pattern. Use the aiming points on the nightsight reticle (Figure 5-13) and the range settings on the mounting bracket. Center the nightsight's reticle pattern within the field of view (FOV). Note that it may not be centered even if it appears to be. To ensure it is, rotate the azimuth control knob either way until it stops. Then, rotate it back the opposite way, counting the number of clicks until it stops again (this may be any number of clicks between 200 and 600). Divide the number of clicks in half, and rotate the knob in the original direction by that number of clicks. For example, if the total number of clicks is 500, rotate the knob back 250 clicks in the original direction. Center the elevation using the same procedure with the elevation control knob. The total amount of elevation clicks also varies between 200 and 600.
b. Adjust the Reticle Pattern. Before adjusting the reticle pattern, the grenadier should fire three 5.56-mm rounds, then retighten the mount wing nuts to securely seat the sight. Once this is done, the grenadier fires at a 10-meter target, because hitting and spotting this target is easier than hitting a 25-meter target. This procedure may be performed in daylight using the daylight cover:
-
(1) Turn the sight on and adjust the reticle intensity to the desired
level of illumination.
(2) Place an M16 25-meter target at 10 meters and stabilize the weapon.
(3) Fire a 5.56-mm round at the center of the target and mark the hole the round makes.
-
(a) If the round misses the entire target, reseat the sight exactly as
previously described.
(b) If the round hits the target but not within 20 centimeters (8 inches) of the center, adjust the azimuth and elevation controls to bring the impact point toward the center of the target, then fire a second round. Continue to fire single rounds and adjust the controls until the rounds strike within the desired distance from the center.
(4) Once the reticle is adjusted, move the 25-meter target out to 25 meters and zero the grenade launcher. DO NOT REMOVE the nightsight from the weapon until you have obtained a zero.
c. Zero at 25 Meters. This zero is not recorded. To obtain a 25-meter zero, the grenadier must--
-
(1) Stabilize the weapon.
(2) Center the reticle's zeroing range aiming point on the target aiming point (center of the target) (Figure 5-13). Fire until you obtain a good three-round shot group. Triangulate and locate the center of the shot group.
-
NOTE: Even if the nightsight is dismounted and remounted on the
same weapon, some changes in its zeroing will occur, so it must be
zeroed again.
-
(3) Turn the azimuth and elevation control knobs to adjust the sight
reticle. Move the center of the shot group 9.8 centimeters (3 7/8
inches) below and 4.2 centimeters (1 5/8 inches) to the right of the
target aiming point (Figure 5-14). For example, if the shot group is
high and to the left of the desired impact point, adjust the elevation
down (DN) and the azimuth right (RT). One click of the azimuth or
elevation adjustment moves the strike of the round .63 centimeter
(1/4 inch) at a range of 25 meters. Two clicks move the reticle about one
square on the target.
(4) After adjusting the reticle, assume a stable position. Place the reticle aiming point on the target aiming point, and fire three more rounds.
(5) Repeat Steps 4 and 5 until the rounds strike within a 3.2 centimeter (1 1/4 inch) circle in the desired location 9.8 centimeters (3 7/8 inches) below and 4.2 centimeters (1 5/8 inches) to the right of the aiming point, or until you have fired 12 rounds, whichever occurs first. If you are unable to zero the AN/PVS-4 after 12 rounds, the trainer must send you to remedial training.
(6) Confirm the zero on the grenade launcher range using a 200-meter target. Place the nightsight into operation and use its reticle, which has two parts. Use the vertical line in the upper part of the reticle to estimate range and the lower part to aim the weapon.
-
(a) Set the range as estimated on the range indicator of the mounting
bracket (Figure 5-13).
(b) Engage the target, placing the aiming point of the sight reticle on the target's center of mass (Figure 5-14). Fire the weapon using all your marksmanship skills. You have confirmed the zero if two of three rounds strike within 5 meters of the target.
FIGURE 5-14. ADJUSTMENT OF ROUNDS.
Night or limited visibility firing trains grenadiers to apply the fundamentals of grenade launcher marksmanship while using the AN/PVS-4 nightsight. This training increases the grenadiers' confidence. Each grenadier learns to zero the M203 to the AN/PVS-4 on the 25-meter range, then fires at one area target on the M203 grenade launcher range. The grenadiers are instructed before night firing in its objectives, fundamentals, fire commands, and targets. The unit is organized in firing orders based on the range constraints. Each firing order should consist of a grenadier and assistant. The assistant performs his duties in a manner similar to day record fire. Night record fire consists of one task: Station 3, Task 6, midrange fighting position (night), area target.
a. Load one of the three rounds allotted.
b. When you receive the following fire command, repeat each element as it is given:
GRENADIER
FRONT
3 ROUNDS
200 (AUTOMATIC WEAPON POSITION)
AT MY COMMAND
c. Acquire the proper sight picture, and announce "Up" to the grader.
d. When the grader gives the command FIRE, engage the target given in the fire command until you hit it. Fire any remaining rounds at the second target. You need no other fire command. For each round you fire, your assistant announces "Hit" or "Miss."
5-16. NIGHT RECORD FIRE QUALIFICATION STANDARDS
Before firing, each grenadier must know the tasks, the time and ammunition required for each, the procedures to follow if a stoppage occurs, the penalties for failure to stop firing when commanded or signaled to do so, and the method used for scoring targets.
a. Time and Ammunition. Firing Table II (Table 5-2) provides the night firing task and its time and ammunition requirements.
b. Stoppages. The procedure for stoppages is the same as for other qualification firing exercises.
c. Penalties. The procedure for penalties is the same as for other qualification firing exercises.
d. Target Scoring. The target-scoring procedure is the same as for other qualification firing exercises.
e. Conditions. Night record fire trains the grenadier to engage targets between 150 and 250 meters under ideal moonlight conditions.
