b. Standing Supported Position. Demonstrate the standing supported position, then have the soldiers assume it also (Figure 5-3, page 5-4). Instruct them as follows:
(1) While standing in an individual fighting position or behind a support, place the bipod legs to your front. Place it at such a distance that you must reach for the round.
(2) Spread your legs a comfortable distance apart, keeping them straight. Place the round on your shoulder muscle.
(3) Lean forward against the wall of the fighting position to support your body from the waist down, so that you are in a stable firing position.
(4) Grip the sight as you did in the sitting position. Pull backward and down, while straightening your upper body slightly; this removes any slack in the bipod.
(5) Place your upper body, arms, hands, head, and eyes in the same position as you did when you assumed the sitting position.
c. Kneeling Position. Kneel, and spread your knees a comfortable distance apart. Position the bipod so that you have to lean forward to position your eye in the eye guard (Figure 5-4). Grasp the sight as previously described. Assume the same upper body position you did for the other firing positions. Place the round on your shoulder muscle, keeping it tight against your neck. As you lower your buttocks to your heels, take the slack out of the bipod. Try to sit on your heels so you will have a stable firing platform.
5-5. M113 INSTRUCTIONAL TECHNIQUES
Certain instructional techniques apply only to M113-equipped units. (See Appendix E for more information.)
5-6. SIGHTING, AIMING, AND FIRING
Once the gunner has mastered the firing positions, the instructor can teach him how to sight, aim, and fire properly.
a. Sighting. Place the eye in the eyecup and pull the weapon tight enough against your eye that you cannot blink. Wrap your small finger around the front of the firing mechanism to add pulling force and to help keep the weapon tight against your eye. Visually select a target, and then acquire it through the daysight or nightsight by adjusting the upper portion of your body.
(1) Keep the weapon tight to keep the sight picture.
(2) Do not move your eye in the eyecup. If you move your eye, you will see the side of the telescope prism, which will blur your sight picture.
b. Aiming. Confirm that the target is within range by using the stadia lines. Place the cross hairs of the sight on the center of the target's visible mass. Regardless of the target's range or speed of movement, keep the cross hairs on the firing point until after you have fired and observed the impact of the round. To maintain the proper sight picture on a moving target, you have to move the upper portion of your body laterally (sideways). When you fire from a seated position, never rest your elbows on your knees. This transfers any movement of your leg directly to the sight.
c. Firing. Fully depress the safety before you try to squeeze the trigger. Then, squeeze—do not pull—the trigger. Since the Dragon has little recoil, many gunners move more when they pull the trigger than when they experience the missile's launch effects (recoil and backblast).
