Most of the incidents named in the last two posts mention situations that a chain of command probably wouldn't want to get out there. Other soliders going bonkers and having to be restrained by your own people? Pulling local civilians out of your minefields? Mulcahy doing the emergency trachea surgery in the field when he wasn't supposed to be there in the first place?
Hawkeye had to repel out of a chopper once, dressed as Santa, under fire, to work on someone in a foxhole. Most higher commands would see his record for insubordination and decide they wouldn't want to give a medal to someone like that regardless of the awesome job he'd done.
No, I don't any chain of command giving medals for most of that stuff.
I've seen way too much of this, "It wouldn't look good to the next echelon if I put this in for a medal" thinking in the Army personally.
