I Really Need Advice As To What To Do For My Military Choice?

Wow! I really admire you for the decisions you are making. That is so great! I would suggest (like a few others before me) that you start by taking the ASVAB test. I know the Army has a 'practice test' they call the EST and you can do it there. There is no cost and you are not obligated to go into the Army. I would recommend the Air Force or Coast Guard for your branch of the service. Reasons have already been laid out in previous responses. Good luck and blessings with your future.
