To start things off I would pay off all of my debt. And after the Air Force nullifies my contract (if you gain a certain amount of money, your contract with the military is terminated), pay off all of my wife and I's family debt. Buy a nice house and a few cars, blowing a couple of million you might say. Say half is taken for taxes, that leaves me with 200 million to play with (rounded down). so... after spending say, 25 million, I would put the other 175 million and collect interest, living off that for the rest of my life.
