In one word, stubborn. The officers I saw ranged from assholes (who salutes in the field?) to normal nerds with a history degree. The enlisted was really diverse, it ranged from frat bro types, wanna-be the bad guy from avatar 2 types, guys waiting for their contracts to end, guys who joined for their greencard which I think is particularly fucked up systemically, and a couple of nerds sprinkled in too. The officers didn't really interact much with the troops off duty which was a bit strange for me, usually where I'm from while they still have separate messes it wouldn't be unusual for an officer to be invited in after an exercise by their subordinates.
