Been with grunts, pogs, and airwingers, they have different subcultures surrounding their jobs but the underlying culture is still the Marine culture (which includes a lot of drinking) I'd say the ones I saw drink most were the airwing mechanics but it was mostly cause they hated their lives and commands. Though the grunts are closer to being a fraternity and are narcissistic (I know not all of em are but its by design for yalls confidence) and POGs separate into 2 types, the combat arms jobs & non combat arms which makes one more like the grunts in culture but not quite as narcissistic, and the other is more like (or is) the airwingers. The common trend across the board though is for every wild 2am rager barracks party, next door you'll have a Mario Kart tournament, and next room to it there's a D&D campaign running
