Nazi Hunters

With as much apparent research the producers did into the details of each of these Nazi series of events, you'd think they could get something like military rank insignia correct. They show actors described as key US Army Majors but wearing Captain bars. USA Colonels wearing 2 General stars. US Army NCOs in USMC uniforms.

When a documentary doesn't get the simplest of things correct, I have a hard time taking for granted that the more obscure things are correct. All that research into the Nazis and they didn't do any research into "What insignia would a Major have worn?". Is there nobody on the production staff that's ever been in the military? Nobody who's ever watched the news or an (accurate) movie that might speak up and say "Wait, I don't think that's right".

I hope that's all ten lines required. Seems like a silly requirement.
