Bachelor's degrees are preferred, not required for any regional (I can think of.) I'm not sure what your free time is like, but if you can take or CLEP some classes towards even an associate's degree I would. I know the Air Force offers a two year degree through the Community College of the Air Force. Once you start flying for a job you can finish a four year degree online.
Also, I'm not insinuating you have done anything, but be a good person legally....i.e. avoid things that may *seem* trivial, such as speeding tickets. So obviously, anything more than that is a no-no. I just know what my military experience is like--a bunch of young folks with lots of pent up energy, go drink and party hard from time to time.
