Continuity: The head SS-Sergeant is referred to as a "Hauptscharführer," however he wears the insignia of a "Sturmscharführer" which is one rank higher.
Errors made by characters (possibly deliberate errors by the filmmakers): In the death shower scene where a large number of naked women were led to the chambers, one of them could be seen keeping her bra and panties on.
Continuity: When Sasha moves in to help the man dishing out food who was beaten, an SS officer points a luger at him but in the next scene when he fires in the air and tells everyone to go to work he is holding a Walther P-38.
