Maybe we could have some sort of inner-work communication like that? Most businesses have them on an intra-net as a way for the employees to blow off steam, and stupid shit like that gets posted all the time. Whether it is strictly 'official' or not, is a different story entirely. I think this would be a great way to really bring home the feeling of work time.
I don't think many people realize how isolated this kind of place is. No base leave (I'm assuming), no contact with family or friends, this literally is the soldier's lives now. These other recruits are now your family and are just as dysfunctional as your one from home. In fact, they may be the only ones you can turn to when your dad sees you as a Mechanized monstrosity after the war and disowns you as a 'heathen abomination to god's eyes.'
They'd have after hours, they'd have amusements of some sort (Probably movies and the like to keep them sane), fights, relationships, office communication, sexual harrasment, alpha and beta behavior, silly pranks, the scientists calling the soldiers Jarheads and Monkeys, the soldiers calling the scientists Eggheads and Braniacs, egos, love, hate, bad food, bad hair days, impromptu pushup tournaments, Writeups for shitty behavior, reprimands for slugging the racist on the team, black eyes, broken hearts, suicide attempts, anxiety over the next mission, PSTD, addiction recovery, therapy, basketball after hours, haircuts, and sooooo many more things that I just can't cover due to alien Gene therapy, Machine mods, psychic troops, live weapons, alien attacks, exalt infiltrators, Security constrictions, and the general atmosphere of a WAR being fought at your doorstep, and a disconnect on realizing that the world at large will never know that you died, though you can see your house on fire from the display.
This shit is deep.
