Audio problem: Season 3, Episode 68, "The Duel". Sometimes the tank's co-axial machine gun is firing, but no gunfire sound is heard.
Revealing mistake: Season 3, Episode 68, "The Duel": The prop wash from the helicopter filming the overhead scenes are evident as everything (dust, twigs, leaves, etc.) is being blown around.
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: The German tank has its main gun traversed to the rear of the tank as Sgt. Saunders is trying to climb aboard. A following shot shows the tank with its main gun pointing forward, then the next shot The Gun is facing toward the rear again.
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.
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.
Audio problem: Several times the German tank fires its co-ax turret machine gun. There is gunfire flashing, but no machinegun sound.
Continuity mistake: Season 3, Episode 68, "The Duel". As Sgt. Saunders is trying to board the tank on its back deck, the tank's cannon is pointed rearward. A subsequent shot shows the cannon over the front, then the next the cannon is over the rear again.
