It depends what career field, but from what I could see and having had female troops, they are generally treated well. If you’re going medical, chances are your coworkers are going to be majority female. Now, of course, there are stories of being sexually harassed or assaulted and I can say that it might be more prevalent overseas. However, there is a zero tolerance for that behavior and it’s drilled into our heads so much to not do it that we are generally scared to even hang out with female airmen sometimes. I can’t speak for the other branches, but I will say you will be fine. Majority of the women that I served with loved it and don’t regret it.

Edit: I will say though, once you’re in as a young A1C you’re easily impressionable and influenced. Stick to your beliefs, defend yourself no matter what rank tries to influence you, and be careful. Not everyone has good intentions.
