Which branch should I join?

I was in the Active Army for 4.5 years. Joined when I got out of high school back in 2005. My MOS was a 19Kilo, M1A2 Abrams Armor Crew member. In 2 years and 10 months, I got promoted to SGT; E-5. It was good stuff for the most part. But yea, alot of hurry up and wait. Served 2 deployments in Iraq. Seen some ****, got blown up, lost a couple friends, who I will never forget. :( Anyways, wouldn't trade it for anything. I am glad I did what I did. I guess initially, the Air force to me was weak. I wanted to be an actual combat soldier, so the Army fit my needs. I agree in the Air force, the pay is better, living conditions, food, is all better...
