Well, fighters pilots and such wear patches from Grumman, Lockheed and so forth, extolling their aircraft...and in that vein, the class patch from the Angrishaam Boat Design Consortium at the Annapabar Yards.
How about The Black Knights Noblemen's Acrobatic StarFighter Team (a nod to the Blue Angels and the Thunderbirds) or Squadron patches and Ship/Station patches?
