Revealing mistake: When trying to take the warehouse, we see a German machine gun position in a lower window. Pay close attention to the brickwork below the window. There are several marks visible that all end up with a bullet hole in the middle of them, hiding the charge for the effect. (00:14:30)
Continuity mistake: When Nixon and Winters are discussing being sent back home, the shaving foam by Winters' left ear keeps changing in size. (00:22:14)
Replacements - S1-E4
Continuity mistake: We see Cobb firing over a small wall that is disintegrated by mortar fire. The camera does an instant cut and now Cobb is just hiding, not firing. (00:36:20)
Replacements - S1-E4
Revealing mistake: Just as the one soldier is sent flying over the wooden fence surrounding a building, you can see break away marks on the post where he will hit it. (00:34:40)
Replacements - S1-E4
Continuity mistake: Just after the Sherman has knocked down the telephone pole we see two German guys up on a roof. In the long shot there is a bullet hole in the brickwork in front of them and in the close up it's gone. (00:34:30)
Replacements - S1-E4
Visible crew/equipment: When the damaged Sherman is from behind rolling forwards, two crew members can be seen guiding it in white T-shirts through the hedgerow. (00:33:20)
Replacements - S1-E4
Revealing mistake: Just as the Tiger fires its second shot and hits the garage, look closely and you can see where the break in the wall is going to appear. (00:32:05)
Replacements - S1-E4
Continuity mistake: When the medic is shot while attending to Patton, he is shot in the left leg but holds his right leg while on the ground. (00:27:00)
Replacements - S1-E4
Factual error: Miller states he got a "Presidential Unit Citation" ribbon as part of the Normandy landings. However until Jan 1957, it was called a Distinguished Unit Citation. (00:07:30)
Replacements - S1-E4
Visible crew/equipment: At the end, as they are moving out there is a high shot of two trucks driving towards the camera. The first truck reflects the camera shadow on the ground. (00:52:20)
Day of Days - S1-E2
Revealing mistake: When placing the German grenade into the barrel of the German, gun you can see the cord used to set timer is still attached. (00:36:40)
Suggested correction: The cord doesn't have to be fully removed for it to work so showing it like that is not a mistake. The grenade will smoke quite a bit if the primer is ignited so even if the cord isn't fully removed they'll know quickly enough the pull was hard enough to ignite it.
Day of Days - S1-E2
Continuity mistake: Winters, just before the assault on the 88 Battery, holds up his hand to give a signal to the other members of the team. Camera cuts and he makes the signal again. (00:29:10)
Day of Days - S1-E2
Visible crew/equipment: Early on the camera pans from outside the aircraft into the jump door and looks at the men. When the camera moves in a shadow moves over the guy sat by the door. (00:06:20)
