I know that my grandpa and uncle are Vietnam vets, dont know anything else though.
But I do know:
Grandpa was put in the brig for three months after he called his Commanding Officer a lier after he was accused of falling asleep on gaurd duty. (He really did fall asleep, stubborn man he is.)
My uncle went AWAL, that war messed him up.
I'm sure more of my family has served, don't know who though.
