To lay down suppressive fire supporting a fire-and-maneuver operation, where you fire while your buddy moves to his next position:
1. Follow steps 1 through 4 in the directions on engaging targets. Have a full magazine ready to load into your rifle.
2. Determine the path your battle buddy will follow to reach his next position, so you don't fire over there and shoot him.
3. As your buddy moves, fire wildly toward the enemy, but away from your buddy. You're trying to keep the enemy's heads down so they won't shoot at your buddy while he moves.
4. If you run out of ammo while he's moving, press the magazine release, allow the magazine to fall out of your weapon, insert the new magazine quickly, press the bolt release and start shooting again.
To lay down suppressive fire supporting a fire-and-movement operation, where you fire while YOU are moving to your next position:
1. Load a full magazine into your rifle. Put it on the burst position.
2. Scream "MOVING!" at your buddy.
3. Look quickly to determine your next position. Try to keep it no more than three seconds from where you are now.
4. Look to see where your other squad members are, so you don't shoot them.
5. Get up and run kinda squatted over (if you stand straight up while you move someone WILL shoot you), and shoot at the enemy while you're running.
6. Get behind cover as fast as you can.
