I was denied an 18x contract for childhood surgery and, attended and failed selection as a regular Army medic. The reason I was not selected was low physical fitness. For me maybe being Infantry would have helped to get myself selected, as they were the only guys in shape around my old unit, but my attitude and poor training desisions
ultimately caused it.
Any problems you may have can be different, but there is tons of useful info on this site, PT, nutrition, MOS education...etc. Everyone suggests using the search button, and so I do. Average soldiers off the street like me realy don't have skills or experience worth posting. I will be 28 or 29 when I return to selection. I was 23 the first time. Most of the guys on my team who were selected were around that age anyway, and some of the better ones in their early 30's. You asked about employment opportunities down the road, my suggestion is the GI bill. The military is a career, so in leaving one there is no set up for another. You would not ask a nurse or high school teacher what they want to do 5-10 years from now. Thanks for giving me permision to post on this site.
