before you decide make sure you look at all the other branches. I quickly joined the Army National Guard and then after i decided i liked the Military so much that i wanted to go Regular Army and it took forever to do. So be sure that is what you want before you sign. Yes, you can join with a GED. And also you get to pick your job and get the job you want they will try to talk you into other jobs but only sign if you get the job you want. And good luck you will not regret serving your country. It probably the best decisiion I ever made in my life. Good luck
