The only thing I can say is that if you had thoughts of joining a the military, you probably would have entertained them before being arrested. Trying to avoid punishment is no reason to join. In fact, its a disgrace to those who are there simply to give there lives for a cause they believe in. Its an ounce man, you wont be going to jail. Take your parole, finish junior college, and if you want to go to another school, take out some student loans and go. Nothing in life is free, and the military pays for school because of what they take from you. For many people, thats a large price than they realize.
