In my 8 years in the AF, I worked with lots of Navy people (as well as Army and Marines).

The Navy is probably the 2nd best branch to be in. They respect their people a lot more than the Army or Marines, and they pretty much let you do your job and leave you alone the rest of the time.

On the other hand, you will most likely be on a ship (or submarine) for months at a time, for the majority of the time you're in. So if you love traveling, and aren't too attached to people at home, the Navy is a great choice.
