If you qualify you may want to look into some of this advice talk to a military recruiter. There are tons of jobs in the military and when choosing a job you can go one of two routes:
1. Select a job related to something you want to do as a civilian. This will give you background and training in that field but give you an advantage over others with comparable civilian training. For example, a civilian may put on their resume that they have a certification in xyz mechanics. The military vet, however, will put that they have certification in xyz mechanics AS WELL AS rifle marksmanship, patrol techniques, land navigation, first aid, etc.
2. Or you could select a different job in the military knowing that the military training, experience, and background put you a leg up anyway, plus get the money for college. There are plenty of jobs in the military that have no civilian equivalent, but resume bullets like armed combat patrols or guard duty at a secure military installation don’t look too bad as experience for any job.
Obviously I don’t know you but you seem like you might have the energy to pursue this. I’d recommend doing some research and then talking to a few recruiters. When I was still in the Guard they were offering the GI Bill and tuition reimbursement up to a certain percentage. I’m not saying that this is always the case, but I knew some people who were literally making money to go to school. At the very least it puts you in a career field where you’ll work with guys every day with much more college debt than you because of the college money it received.
If nothing else, most people that have been through basic training and then active duty or Guard/Reserve training come away with a bearing, discipline, and structured way of doing things that most people, including employers, look for.
