Pros
Free healthcare and a paycheck. Choose a career that involves you getting a TS//SCI clearance to maximize your time spent in the Air Force. If you like traveling -- to the desert, this job is you! Educational benefits are great if you aren't stuck working 12-hour mid shifts on a rotating schedule; this kind of hampers utilizing this benefit. Apparently they are revamping the GI Bill to actually make it possible to go to school full-time when you get out as well. If you are lucky, you'll have a bonus in your career field; though this is subject to change at any time.
Cons
Injustices everywhere. Motivation to excell is 0; at least in the intelligence community. The people who get recognized for awards aren't those who work the hardest at honing their craft, it's those who participate most often in the squadron events abandoning their primary, and most important, duties. Both the rating system and promotion system are flawed as well. The single biggest factor to your success in promotion in the Air Force is how much time you spend studying a book that reviews military history and mundane details concerning the wear of the Air Force uniform. The other portion consists of your "job knowledge". This portion of the book is written by someone who can't read or write the English language. Not only do you have to try to translate what this person is trying to say, but you have to understand information that you have never applied anywhere in any fashion; this is how they assess how well you know what you are doing.
