My buddy decided to join the Navy a wilhe back. He's in DEP and he wants to work with computers. I went the Marine Corps route, and after I showed him he can do what he wants in the Marine Corps, hes become more intrested. If he wanted to switch out of Navy DEP and join the Marine Corps, does he have to wait a certin ammount of time or does he just let the Navy recruiter know, get discharged, and then sigh up with the Marines? Thanks.
