Go Navy!!
I'm getting ready to graduate from the Air Force Institute of Technology in a week and then head down to flight school. Granted, I haven't experienced the fleet, but after a year with the Air Force, I know I made the right decision.
The Air Force is very corporate. They have forms and plans for everything!!! If you like knowing exactly what you can and can't do and don't enjoy peering outside of the box you are placed in, join the Air Force. The type of person in the Air Force I saw at AFIT is very different than in the Navy guys I know. Don't get me wrong the Air Force has great people, but the Air Force guys are different. I don't know how else to put it. They are just different. The Navy guys on the other hand are much more relaxed, easy-going, and fun to work with. Our life isn't just the Navy, we have other things going on. Where as with some of the Air Force guys, well that is their life. Also, unless you are an aviator, you are a second class citizen or worse in the Air Force.
In my opinion, granted I have little experience to draw on other than my year with the Air Force, the Navy is the way to go. I have had a lot of the 0-3's I go to school with tell me the same thing. I completely agree with them and I'm glad I'm heading down the path I'm on.
