Bridgehead - S2-E2
Continuity mistake: Billy's father, previously established as dead, sends his son a letter in this episode.
Masquerade - S2-E3
Continuity mistake: At the start of the episode the barrel points to his left, during the close ups talking to the men in the jeep it points to his right, and as the jeep pulls away within the next frame it switches from left to right. Also, the men behind the jeep go from sitting to marching instantly. (00:01:00 - 00:02:00)
Continuity mistake: When Captain Steiner is staring at Saunders through the window, the curtains are set mid level, but from inside the house they are set higher. (00:36:00)
Continuity mistake: Re-used footage causes three characters who were earlier captured by the Germans to be seen, in one shot, marching in Saunders' squadron.
Continuity mistake: 5 German soldiers find the farm house, but during the battle 6 of them get killed. (00:23:45 - 00:27:30)
Continuity mistake: The Gun Richard Jaeckel's character is carrying changes, between one shot and the next, from an MP40 to a 98k rifle.
Continuity mistake: Saunders loses his helmet getting into the truck, but is wearing it again in the next shot.
Character mistake: At the start of the episode when the plane is spotted Sgt Saunders says "P-51." The plane is in fact a P-38 Lightning.
Revealing mistake: When the German soldiers are shot and fall dead into the water, one of them raises his head to take a breath, then goes back to being "dead."
Continuity mistake: Mark Richman's character has an empty holster after the crash, but moments later there is a .45 caliber weapon there.

The Short Day of Private Putnam - S2-E28
Revealing mistake: 2/3 through, Beau Bridges comes upon a dead German but you can see the German breathing. Oddly, it's a fairly far shot, so he must have been breathing pretty heavily.
The Short Day of Private Putnam - S2-E28
Character mistake: Hanley's call sign is Checkmate King Two. But his radio man recites, "Checkmate King Two, this is White Rook." Should have been the other way round.
Revealing mistake: In several scenes when they show the front of the barrel of the German machine gun you can see the "blank adaptor" inside the barrel. This is inserted to not allow the gas from the cartridge to escape out the barrel but "blow back" the bolt and insert another round.
