Figure A-5. Alert Carry c. Ready Carry. The ready carry is employed when contact with the enemy is imminent. It allows for immediate target engagement. The buttstock of the rifle is in the shoulder with the muzzle of the rifle pointed in the direction of the enemy (Figure A-6). As in the alert carry, sight alignment and sight picture are achieved as the shot is fired. Marines should always strive for a clear tip of the front sight post and center mass hold. Figure A-6. Ready Carry d. Short Stocking. Rifles may be “short stocked” to increase their maneuverability in an enclosed area and to reduce possible “target indicators” for the enemy (muzzles sticking around corners, for example). The weapon is held in such a manner as to reduce the length of the weapon without sacrificing too much accuracy (Figure A-7). The stock is positioned so that the pistol grip is behind the Marine’s head. The Marine may use his/her index finger or thumb to manipulate the trigger. The handguard of the weapon is placed against the Marine’s cheek, A - 4 MCWP 3-35 .3
