All this is testimony to is that those soldiers who did this violated everything they'd been taught. If the unit was aware of it, then the unit, too, was out of line.
However, in defense of those on the line who get stressed out when their and their buddies' lives are on the line....walk a mile in their shoes.
They're still guilty, but so is the guy in the middle of a riot who shoots someone at his door instead of waiting for them to break through the door.
"5 gal water jugs with outstretched arms" okay......Thems some mighty strong bad guys.
