What do you think it is that makes the bullying follow you? I don't want it to sound like I'm blaming you; no matter if you like someone or not, bullying and harassing them is plain wrong. Still, I wonder if in addition to reaching out for mental health care (if possible), it may be worth using this time as an enlisted man to try to work on yourself as a person. The military is great for instilling strength and confidence in people, and assholes don't bully confident people. You obviously have a lot of anger; I would use that anger to motivate you. Start working out, get strong. Follow the rules and keep your head down so your superiors like you and will have your back. Don't start shit, but stop letting people disrespect you. Stand up for yourself. You are a grown ass man; you don't need to let anyone make you feel less than. Only you can let that shit get to you. No one can make you feel anything; if you don't let them get to you, it won't.

I know it's easier said than done. And I know that reaching out for mental health care in the military is not easy. But you need to stop letting these people make you into a victim. You are giving them power over you! They have no power unless you allow it. Also, I would do some searching in /r/prorevenge and /r/pettyrevenge for inspiration. If I were you I'd be getting some fucking revenge. Military is great for that shit. The best revenges involve getting them in trouble with superiors.

And I know it's probably just healthy fantasy, but just know that any violence stronger than a good ol' fistfight is not going to fix things. Know that if you die, or go to prison, they won. They broke you. You would be letting them succeed in ruining your life. Don't let these assholes be the reason you're in prison for the rest of your life. Also, if you shoot anyone you make the rest of us responsible gun owners look bad. You'd be helping them take out guns away. Don't be that asshole.
