Figure A Targetbox paddle DVCT

(f) The shot-group exercise provides a chance for the trainer to critique the soldier on his aiming procedures, aiming consistency, and placement of shot groups. Assuming the rifle and paper remain stationary and the target man properly marks the three shots, the only factor to cause separation of the dots on the paper is error in the soldier's aiming procedure. When the soldier can consistently direct the target into alignment with the sights on this exercise, he should be able to aim at the same center-of-mass point on the zero range or on targets at actual range.

(7) Ball-and-Dummy Exercise. This exercise is conducted on a live-fire range. The coach or designated assistant inserts a dummy round into a magazine of live rounds. In this way, the coach can detect if the firer knows when the rifle is going to fire. The firer must not know when a dummy round is in the magazine. When the hammer falls on a dummy round, which the firer thought was live, the firer and his coach may see movement. The firer anticipating the shot or using improper trigger squeeze causes this. Proper trigger squeeze results in no movement when the hammer falls. The soldier will demonstrate the ability to properly utilize the fundamentals of marksmanship six consecutive times.

(8) Dime (Washer) Exercise. This dry-fire technique is used to teach or evaluate the skill of trigger squeeze and is effective when conducted from an unsupported position. When using the M16A1 rifle for this exercise, the soldier must cock the weapon, assume an unsupported firing position, and aim at the target. An assistant places a dime (washer) on the rifle's barrel between the flash suppressor and front sight post assembly. The soldier then tries to squeeze the trigger naturally without causing the dime (washer) to fall off. Several repetitions of this exercise must be conducted to determine if the soldier has problems with trigger squeeze. The purpose of the exercise is for the firer to dry-fire six of six consecutive shots without causing the dime or washer to fall. (Repeat this exercise from the prone unsupported firing position.)

(a) If the dime (washer) is allowed to touch the sight assembly or flash suppressor, it may fall off due to the jolt of the hammer. Also, the strength of the hammer spring on some rifles can make this a difficult exercise to perform.

(b) When using the M16A2 rifle, the dime (washer) exercise is conducted the same except that a locally fabricated device must be attached to the weapon. A piece of 3/4-inch bonding material is folded into a clothes-pin shape and inserted in the flash suppressor of the weapon so the dime (washer) can be placed on top of it.

d. Selection of Training Aids and Devices. After training requirements have been established, appropriate training aids and devices can be selected from the TSC. To help in selecting these aids and devices, many of those available and their identification numbers are listed in Table 2.
