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.
The Letter - S5-E7
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 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.
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.
The Letter - S5-E7
Revealing mistake: The same strawberry-blonde haired stuntman (Paul Busch) is used three times: first as an American G.I. being shot, then as a German soldier being shot, and again as another American G.I. being shot - all in the same battle scene.
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.
The Gantlet - S5-E20
Continuity mistake: As Sgt. Saunders hides from the pursuing German soldiers, a German soldier comes abreast of Saunders and raises his hand to his face twice.
The Gantlet - S5-E20
Continuity mistake: The passenger in the truck cab is not wearing a helmet in the long shots, but the close ups show him wearing his helmet.
The Gantlet - S5-E20
Revealing mistake: During the close combat scene between Sgt. Saunders and the German soldier, it is obviously Vic Morrow's stunt double doing the heavy action and fighting.
Continuity mistake: After McCall shoots the German soldier dead, the German's body changes from lying face up to face down. Also, the dead German's helmet, which was lying two feet away, is now nestled next to the German's head.
Continuity mistake: The close ups of the dead lieutenant show his teeth exposed while the long shots show his mouth closed tightly.
Revealing mistake: A German soldier steps out of a doorway ready to throw a grenade, but he gets shot, dropping the grenade a couple of feet in front of him. However, the explosion from his dropped grenade occurs from within the doorway itself.
Revealing mistake: When Sgt. Saunders throws a grenade at the German soldiers shooting at him from behind a crate, the grenade lands in front of the crate, but the explosion is actually behind the crate, where the Germans are.
The Letter - S5-E7
Continuity mistake: After an American soldier is shot in the back during the first battle scene, his body disappears a few shots later.
Factual error: As Caje provides cover fire for Sgt. Saunders, Caje's M-1 rifle fires more than the eight shots it holds.
Factual error: As Stevens charges the German machine gun nest, he fires more bullets than his M-1 rifle could hold (the rifle could hold only eight rounds per clip).
