I was a military brat for 18 years (father was in AF) and my sister graduated from the United States Air Force Academy and is currently a Captain in Military Intelligence. I support anyone who joins the military for the right reasons.

Do some research on all the branches before you decide. It sounds as if you havent a clue about the positions offered in each branch. Take as many practice ASVAB tests as you can. The better your ASVAB score, the more choices/options you get for a career path.

Just remember, when you sign the dotted line... it's a CONTRACT. It's not some crap job at the mall where you can walk out if you're not happy. In this case, you're stuck. You may be placed into situations in other countries where your life is on the line. If you can't come to terms with that, don't join. We don't need you. We don't need another waste of space thats going to complain about having to fulfill the contract they signed.
