Continuity mistake: In the final war scene, when they first run out of ammunition, Grady puts a belt into the coaxial .30, and as he is firing you can see the end of the belt, but in the outer scene when the German is hitting war daddy with a shovel, the coaxial is still firing.
Continuity mistake: In the final battle scene, day turns to night in a moment. From the inside view of the tank, it is still daylight outside. (01:43:55)
Continuity mistake: In the scene just before the Tiger tank fires on the American tanks, there is a shot taken of the four tanks rolling along at a distance where it is quite clear that the two tanks in front have long barrels on their main gun eg: M4 Shermans with 76mm high velocity guns. Then in the next shot that second long barrel tank is gone and now there are 3 short barrel tanks and only Fury with the 76mm gun.
Continuity mistake: In the beginning of the film when Wardaddy jumps the German officer riding the horse, he is holding him down with his left hand while stabbing him in the gut with his right hand. When the shot changes at the final thrust, he is holding the knife with both hands as he twists the knife to pull it out of his left eye socket. (00:03:15)
