I had the pleasure of re-watching the "Star Wars Holiday Special" recently. There's a scene where a TK onsite at Chewbacca's home is trashing his son Lumpy's room. He and Han get into a tussle and he bites the dust and falls off a tree. Well, he gets a call from CMD but is missing. The officer is looking for a "B-4711..." rather than "TK-4711". Remember, this was filmed right after ANH, before ESB. Thought it was interesting...it's @ 1:42:00...
I like Trooper Korps...but always thought of it as "Trooper Killers".
