Sad. I can't even begin to imagine what combat like that must do to a man. Makes you wonder if dying during combat beats the alternative of trying to live with the after effects.
Your comment is far more accurate than most will ever realize.
My only other comment and I will stand down on this one:
"Master Sgt. Andrew Christian Marckesano - you can stand down now. Your watch is over. Others will take it from here. May you be resting in God's arms Brother."
