OR, You get lots of technical training, you sleep in AC or Heat your tables usually aren't folding there are lots of pretty women running around and you get a job with a hair cut and money for college.
USAF. Good Choice.
If you want to be a Marine, and you WANT to be part of something, truly part of something special, then the Corps is a great choice. I don't think it's the answer though for folks who are have not been planning and looking for just what the Corps has to offer.
I've never heard the Corps was difficult to get into though, Muscles Are Required Intelligence Non Essential... MARINE.
Kidding... But seriously though, I'd Vote AF first for education, treatment, and over all lack of opportunity to get your a55 shot off. You won't be going door to door with an M16 while in the Air Force.
Like I said though, if your looking for someone to look after you, take care of your every need, be your Brother, Mother, and Father the Corps is a great way to go. They are a tight knit bunch.
