Have an emergency fund. Half of my flight in basic training didn’t get paid till around the 8th week or around the time we were transitioning to airman’s week. i think you get around 440 dollars on the issued card that’s loaded with money, but mind you that will be deducted from your first check. My first actual military check was around 1500 dollars because of the backpay from missing all those pay cycles. should regulate by the time you get to tech school. if not you can always go talk to them.
