Continuity mistake: Season 3, Episode 68, "The Duel": When the truck first blows its tire, it is in a very muddy, watery patch of road. Subsequent scenes show the road is dry except under the truck where the truck driver is trying to jack up the truck to change the blown tire.
Continuity mistake: Season 3, Episode 68, "The Duel": Opening shot shows a "German" tank with the commander's cupola on the left side of the turret. As the "German" tank is really an M-41 Walker Bulldog from the Korean/Vietnam era, the cupola should be on the right side of the turret as the majority of American tanks since WWII have that feature. Obviously, the film was flipped.
Revealing mistake: Season 3, Episode 73, "Losers Cry Deal", a GI in the squad fires a rifle grenade at a German machine gun position in a window of a building. Not only does the rifle grenade miss the mg position, it misses where the pyrotechnic representing the rifle grenade exploding was planted.
Factual error: Sgt. Saunders is looking at a color photo of his kid brother in a letter from home. Aside from being prohibitively expensive for the average family to afford, color photos were not common. Also, the wartime rationing of photo chemicals for color film used by civilians would not be available.
Continuity mistake: The first shot of the German tank shows the tank commander's station on the left side of the turret; later on and for the rest of the episode the TC's station is shown on the right side of the turret. Note: WWII German tanks had the TC station on the left side of the turret while most American tanks during and after WWII had the TC station on the right side of the turret. The tank used in this episode was a Korean/Vietnam War-era American M-41 Walker Bulldog.
