I'm in the Army National Guard, haven't been to Iraq yet though. In my experience so far in te military, I would also go for the Air Force. Several reasons (some I wish I would have known before I joined the Army) (Also, this is only my opinion, so of coarse it's not going to be the gospel):
1. They are cared for a whole lot more
2. More organized
3. Paid more
4. Usually have the better looking females
5. Don't have to go into combat zones (at least not that I know of)

There a a bunch more. I still like what I do (Information Technology) but I think it would have been a better choice to go AF.

But that's my 2 cents.
