I always figured Nazi episodes were written mainly so they could use the various Nazi props and costumes that most studios have lying around from WWII movies. Great way to save money.
They could have at least tried to get the uniforms *accurate*.
If you're writing something to reuse props on the cheap; presumably getting the cash to improve on those props is out of the question.
Actually I meant the proper *use* of the uniforms. As it stands, there was no pattern to it. They just basically put random SS, Gestapo, etc. uniforms on anyone they could find. One thing they *did* get right is McCoy's rank (he wears the correct insignia for a Colonel, which is the kind of Nazi uniform Kirk asks for).
