A bit, outside of weapons school we tend to be a little intentionally raunchy without the sts game. At Nellis, I'd say it's a strange blend of that and a little fighter pilot culture, but not nearly to the level of saying something like skulling.
Our enlisted crew members are traditionally very accepting, but more along the lines of no matter what your kink is they will embrace it. Google naked gunner hug....
We tend to bend the fraternization rules as my previous post implied, making that work relies on the SNCOs and O's making sure the young E's know that while we may be friendly, the boss is still the boss. Usually it works out OK, sometimes you get a young E that doesn't get it, but he almost always gets handled by his enlisted peers. In some respects, that response is probably a lot more severe than what an O would do.
I actually think our NCOs are the best in the AF, and that gives us a lot of lee way. The quality of my NCOs in my last assignment (I'm a staff bitch now) was incredible.
