We had a couple guys go UA when I was active duty. They turned themselves in, did about two weeks on restriction, and were discharged. Guys who wait until they get picked up by the police don't get off quite that easily.

The chances of him being allowed to join another branch are currently zero. If he turns himself in and takes the discharge, there is a very very very small chance (call it one in ten thousand) that he may be able to get into the Army, since they appear to take pretty much anybody right now.
