How do I get into the military(Army, Navy, Marines, etc. if I have a felony conviction? Who should I contact to get in?

You'll need a waiver. Also depends on what the felony was for and how long ago it was.

Your recruiter will have the info you need.

Emland is correct, Depending on so many factors, but you will have to work with the recriter

I'm getting ready to join Army right now. Talk with your recriter. Work with them, what ever you don't hide anything, they will find out. You talk to the Army, or Marines, that's your best bet.

If its violence, with a weapon, it anything domestic you will not get in. Anything else can be waived
