When the group of three medics (wade & 2 others) come on screen watch the far left medics canteen when it gets hit. It's leaking bloody water! No chance of a splash, because it continues to for about 10 sec. Watch the part when the soldiers are fighting the machine gun bunker (sandbag). The camera goes for a panning shot, and look who rifleman #2 is! It's Oppom! Later when he and Capt. Miller are talking in the netted area he's says he hasn't fired a gun since basic training.
