Revealing mistake: Blank .30 caliber machine gun bullets are obvious as the soldier with Little John sets up and loads the weapon.
Continuity mistake: Long shots of the German sergeant shows his MP38/40 submachine gun at his waist and pointed down, but the close up shots of him show the weapon up by his chest, pointed up.

The Letter - S5-E7
Factual error: Sgt. Saunders is looking at a color photo of his kid brother in a letter from home.

The Letter - S5-E7
