The Cut-Throats (1969)

Captain Kohler recruits an outfit of five American soldiers besides himself (dubbed "The Cut-Throats,") to attack a German stronghold to capture battle plans... although his real motive is to steal a cache of jewels that is Nazi plunder. After the enemy soldiers are gunned down, the beautiful women in the compound treat The Dirty Half-Dozen to a stage show and, later, themselves.
