AF enlisted here, and AKA's response is quite adequate for your question. Your post is vague about the promises part though, what where your friends promised? The only thing a recruiter can promise you is your bonus, AFSC and how many year enlistment you decide. Don't let them try to promise you a certain base or country to serve in, because they have no say in that. PM me if you have any questions. Good Luck, the USAF is a great corporation to work for
