The pilot was aired on Tuesday, 10 August 1976 by the American Broadcasting Company (ABC).
Set in World War II, The Rear Guard followed a band of men in the American Civil Defense (c. 1942) who were part of an auxiliary force in the event of an invasion of the United States.
The episode was an adaptation of "The Deadly Attachment", in which a German U-Boat crew are placed under the supervision of the platoon.
As The Rear Guard was a remake of Dad's Army, it included many of the same characters under alternative names.
