The branches you chose have even more branches, which have more branches, more and more until it represents one person. I really don't know, because... well, um...
I think you'll be interested in all of them, because you won't get 'hurt' in branches of the branches you chose. The closest my dad got to 'danger' was when he went to Afganistan. There is much more to the military, but if you don't want dangerous tasks, I suggest not joining sonething like Special Forces (Well, probably only in the UK). There is loads to do that is not dangerous in the Military, but I can't help you because I study British Forces, not American. But you can research if you want. You won't really get 'in trouble', because there is tons of branches to the branches you listed. For everything, you'll have to train, especially becoming fit. I too want to join forces, RAF and stuff, but... let's say in the future, I won't really be dead because I joined. It all depends on the smallest branches, even smaller than yours. Anyway, my sister will vote for me, because I simply can't choose. She says Army, but why don't you research that, and find smaller branches, which aren't as dangerous as you think. For the Army you'll certainly have to become healthy and fit, though. Good luck.

I didn't realise how long my comment was. lol XD
