OK so I have a friend and he stopped going to his drills last year in march. He hasn't went back since. A couple of weeks ago a Sargent came to his house, he wasn't home but the Sargent told his father that they are wanting him to call them because he's AWOL and that he's not in trouble they just want to talk to him. He still hasn't called and probably won't... What will happen if he doesn't?
