Revealing mistake: Blank .30 caliber machine gun bullets are obvious as the soldier with Little John sets up and loads the weapon.
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.
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 Losers - S5-E2
Continuity mistake: Kline removes the ammo belt from the dead soldier twice.
Revealing mistake: The German MP38/40 submachineguns have blank firing adapters on their barrels.
Revealing mistake: The grenade Saunders tosses onto the German tank does not land where the pyrotechnics explode.
Other mistake: When Saunders' tank and the other tank are sparring against each other, closeup shots of the tanks' rear drive sprockets show them moving in reverse, but overhead shots of the vehicles show the tanks moving forward.
