In all of his films, Samuel Fuller--who wrote the story for this film, but not the screenplay--has a character named "Lemcheck". In this film it's a sergeant, played by Harry Bellaver.
Major General Maurice Rose, the real-life Commanding General of the 3rd Armored Division and presumably the character played by Roy Roberts, would end up being the highest ranking and last American general killed by enemy action in the European Theater in World War II, less than six weeks before the end of the war.
