My friend Danny Smith, who was in a pre-enlistment Marine program, think they are called "pollies"? They played a game at the end for the first promotion above Private, the game was essentially who could last the longest in a paintball game, literally the only way you could get out was to call yourself out. He and a girl were just shooting at each other over and over, the Staff Sargent finally called it a tie. She got the promotion because he had already received it for previous actions. They also played a game where they had to hold the "down" push up position for as long as possible, on an asphalt parking lot. He also won that game. My friend the marine <3.
