This is a hell of a thing to have to think about. The senior man should have made the decision. The last thing to go before the collapse of an entrprise be it a combat patrol or a hot dog stand is discipline. Adrenaline, instincts and psychological stress makes a bad admixture that even good discipline can hold together for only so long. We all chose this path and we are haunted at times by making the right decisions and the wrong decisions and IMO only discipline keeps the score even. These men did no right or wrong, they died and 1 walked away from it. Let it be knowing we could have done no better or worse had we been there ourselves.
