There are several items in this photo thats makes me think its fake.
Namely, I'm thinking there are some out of era items:
The canteen, the muzzle cap, the hat, and other clues.
Dont know for sure - as I was not in Nam during that war... but I beleive some of these items didnt come out until the 80's.
I could be wrong.
The least - he had to be a 2nd LT right outta ROTC - Totally clueless. I feel sorry for the guys Platoon Sarge that had to deal with this Butter Bar.
