Navy or Air Force? (read description for specific jobs)?

Lol if there is only one military career you are comfortable with and enjoy for each branch, maybe you should reconsider joining the military... you are not guaranteed your first choice, especially ones as popular as those. Have you already qualified for them?

edit: Oh okay, good :P When I read "I've narrowed it down to two good ones that I would be comfortable with and enjoy" i thought you meant those were the ONLY ones.

Anyway, I'm inclined to say Aerial Gunner, but I'm a little biased towards the AF since that's the branch I plan to join. :P

Go air force. Being on a boat blows and the food usually sucks especially on a carrier. You will jack your knees up and not have as good of living conditions. You're better off in the AF.

AW's work weird hours, have night flights and things like that. Their schedules change depending on the flight schedule. If you're okay with that, you'll like it. It's a cake job. when the AW's aren't flying, they aren't doing much of anything. :) In the Navy, the airdale rates are the way to go though!

I don't know much (if anything) about the air force though.
