Which branch should I join?

I spent 9 years in the Air Force and it was very fulfilling i got to see places that i would never have gotten to see and learned a trade to boot.I joined in 1979 after bouncing from job to job,i had a family to support and no money don't mix so i talked to the recruter and was seeking vehicle maintance but there was a waiting line for that job so the recruter talked me into jet aircraft mechanics [crew chief] i have always been good at fixing stuff so i went for it. I highly recomend aircraft mechanics if you work on cars it's not that difficult to learn to do and you can go to commercal aircraft when you retire/seperate [getting your A/P licence is not hard just some tests,your airforce time in service job is just like going to school] that's what i did i wish you the best of luck in your decision and thank you for joining the military.
