How can I get into the military?

I want to join a reserve component of the military while I go to college to get my degree, and then I would like to go to OCS. The problem is, I have a juvenile criminal history. I received a charge of second degree battery when I was 14, and at 16, I was arrested for three counts of possession of schedule II narcotics. What do I have to do to go about this? Who can I talk to and get recommendations from. I'm an immaculate student and very well-spoken. Not to ring my own bell, but you would never have thought that I would have this type of background. The battery was from a fight that was self defense from a much older guy who I injured, and the possession was for adderall and concerta for cutting weight (wrestling) and one oxycodon I was going to use for knee pain (I had a scope done on it). I figure if I get into the reserves, I can prove myself and have some background for when I apply to OCS. I really need some help here. I've already talked to a Marine recruiter who said it was a no go. I have a Navy recruiter trying to find evidence of my charges. He said he's having a difficult time because they are juvenile charges. I have the feeling he is kind of a slacker. Whatever it takes to become a CO in the United States military, I am willing to do. I prefer the Navy, but any service would do. By the way, I live in Baton Rouge, LA, so if there is someone I cn contact personally around here (say, in New Orleans), I'd go out of my way to do so. Anyone I could write to or call or e-mail, it really doesn't matter, I am willing to do it. Also, I graduated highschool with a 4.4 gpa at the top of my cl a semester early. I have 17 credit hours currently of college at LSU and a 4.0 gpa. I am currently enrolled in the fall semester at LSU taking 16 more credit hours and am determined to keep my 4.0.
