Most battle buddies for first time PCS (From AIT/OSUT to first duty station) tell new joes a couple of things:  Don't fall for the benny bunnies at the bars, and don't marry them. Don't buy a car at any place where another GI you've never met offers to give you a ride there. Don't take out payday loans, talk to the AER NCO first. Don't get a Dumb Private Program credit card (Military Star Card, last I knew)  Retards never listen.  There's a reason I refused getting promoted past corporal.  E5's and above become fucking babysitters.
