When the squad is at the rifle range, Pike wets the forward site of his rifle with his thumb, stating he saw Gary Cooper do it in a movie- presumably Sergeant York. However, in a following episode, "Room at the Bottom," the verger tells the men that the German battleship Bismarck has been sunk. The Bismarck was sunk in May 1941, and Sergeant York wasn't released until later that year. Therefore Pike couldn't have seen the movie at the time portrayed.
