Meet the 501st, Vader's Fist.
The pilot stands for Fodder, the Snowtrooper for Chef, the Scout for Bomber, and the ImpGunner for Impy the Imp Officer.
The two TKs on the left and right are CB, Sniper, Steph, Skippy, and Shorty, while the center trooper is Jet and TV. Sorry, Rebb Al and Marvin are not included. I think that's everyone.
Bomber: "So... if the real 501st is called Vader's Fist, what are we?"
TV: "Vader's Ass"
Sniper: "Wouldn't that just more us MORE lethal?"
