OP,
another thing I REALLY suggest-> getting your ducks in a row. You have a few months. Have him talk to his chief about tuition assistance to get enrolled in college that he'd want to get into. Not saying he HAS to go to college, its just a good idea and a plan C, and may as well get the navy to pay for it while you can. Also, try to arrange your housing situation for when you get out. You get a home of record move, and its a PAIN to get arranged. Start that process sooner then later. Talk to the VA where youre going to be moving to get contacts there. Im sure theres more to do as well. You have a while, and trust me, thats a VERY good thing.
