I'd want to join the navy. Not only because I enjoy being on the water, but because it's the safest branch to join when the people we seem to have the most conflict with are in some middle eastern desert.
So you want to join the branch that had to go find and kill Osama bin Laden (who was nowhere near water)?
I didn't say I wanted to be a SEAL. I'm not Jesse Ventura. A close friend of mine's dad was in the Navy and he's short and potbellied. He was a ship's cook. He has a very good retirement pension and he got to sail around the world. What's not to like. Hell, even I could do that.
