Balderdash. This SOLDIER fought as long as he had anything to fight with, unlike the vast majority of his sorry-ass unit, including his incompetent Commander. IF he were captured, which I doubt, he would have taken the first opportunity to escape, as was his duty.
Two in the back from 20+ feet sounds like either the end of his lone stand when a bad guy got behind him or an unsuccessful escape attempt.
This soldier makes me proud as a blue-striped bantam rooster that my Army DOES still produce SOLDIERS.
I think you're right. That's a most probable scenario, based on released information.
