Plot hole: "The regiment headquarters calling for Corporal Steiner. Come in Steiner." The film starts with this repeating radio message. It's even heard by Steiner and his men who are on their hush-hush job behind the enemy lines: a reconnaissance mission. Calling Steiner just makes no sense, especially with the name.S.Holmes
Factual error: When Captain Stransky urinates at the side of the road after ordering his motorcycle driver to pull up, he zips up his trousers as he returns to the motorcycle. Wehrmacht uniforms had buttons and not zippers.
