The Devil's Brigade

The Devil's Brigade actually existed; its formal military designation was the First Special Service Force (FSSF), and alternatively known as the "Black Devils". It was indeed a joint American-Canadian unit, was comprised of three regiments of two battalions each, and was envisioned for difficult, cold-weather, mountain-warfare missions. The members were known as "Forcemen". Initially earmarked for Northern Europe, the FSSF was first sent to the Pacific, then to the Italian campaign, before finishing its service in southern France in 1944. During World War II, the brigade suffered casualty rates of 39%. Upon disbandment in 1944, each nations' Forcemen were incorporated into their national armies. Veterans of the Devil's Brigade have been meeting each year since 1945, in Montana, at the former training facility depicted in the movie, although in the movie, filming took place in Utah, as a stand-in for Montana.

On Colonel Frederick's office map, Poland has its post-1945 borders and Germany is divided into the postwar East Germany and West Germany.

The copyright date in the opening credits is MCMXLVIII, which would be 1948, not 1968, when the film was actually produced.

The TV version of the film plays with subtitles for the Germans; the video version dosen't include subtitles.
