Yeah, I avoided them overseas when I was in the military. They were like aliens from another planet.
My buddy that's my neighbor now, hates them also.
Some of them were on something like "military police' duty and saw him go into a private home. He was having consensual sex with a woman he knew. They beat him with a club and said it was illegal for foreign troops to have sex with Vietnamese women.
Lack of good leadership in their units for sure.
