Go SWCC, SEALS, or GTFO
But fer reals, congrats man. Don't be stupid with your money. Always be looking at the next step, career wise, and personal development wise. Don't get married, don't buy a car off base, don't get married, save your money, don't get married, don't get sucked into hanging out with the guys that hate the military and complain, don't get married, find hobbies that keep you active, don't get married, travel, don't get married.
Good luck.
