Continuity mistake: As the squad are taking a break on top of a hill, just before the fighter-bomber attacks them, Corporal Job is distributing ammo and Jonesey can be seen walking past in the background with four boxes of K-rations. A moment later, Crapgame and Jonesey are sitting together sharing the contents of the boxes. After Crapgame goes to the jeep for some water, the shot cuts to Kelly sitting by a tree. Jonesey walks up to Kelly with a message from Big Joe - carrying four unopened K-rations boxes.
Continuity mistake: After Oddball's tank gets across the river, the movie returns to the general's headquarters where Carroll O'Connor is yelling at his officers for not knowing anything about the battle. There is a soldier standing behind O'Connor with his hands on his hips and his shirt sleeves rolled up. The scene changes briefly to show the officers that O'Connor is yelling at before switching back to O'Connor. The soldier behind O'Connor still has his hands on his hips, but now his sleeves are rolled down.
Continuity mistake: Near the end of the film as Oddball's Sherman drives into the French town, the amount of ammunition in the ammo holder on the turret .50 calibre machine gun gets larger in almost every shot. As the tank crashes through the bushes approaching the town there is hardly any ammo in the box, up until the second Tiger is ambushed when suddenly there is plenty of ammunition.
Continuity mistake: At the end when confronting the last tank to get the bank doors open, Oddball, Big Joe, and Kelly line up in an alley as if they are directly facing the tank and start walking forward. In the next shot, which is wider and much farther away, you see that they are actually walking down a curved alley and can't see the tank until they come all the way around the corner.
Continuity mistake: When the last surviving Tiger rages in Clairmont, shooting at surrounding buildings, there are a couple of shots, when we see both the tank's gun firing and the 'shell impact' effect. The tank's gun is not always pointed at the exact spot where the 'shell' explodes - it's particularly visible when the Tiger lowers the gun and shoots a hole in a wall, immediately after Big Joe threw a grenade and fired at the tank with his SMG. The hole in the wall appears a good few feet to the left, from where the gun points and the actual projectile would hit.
Continuity mistake: While Big Joe is talking down to the Captain in the boat, Joe is blocking the stairs to the upper deck with his whole body. As the Captain moves up the stairs, Joe is off to the Captain's right. When the Captain emerges from the lower deck, Joe is dead center of the Captain and then moves out of the Captain's path.
Continuity mistake: After Cowboy spots the Tiger coming down the street the scene changes to a view of the three soldiers running from away from the bank from the viewpoint of the Tiger. The Tiger's turret is facing the soldiers. In the next shot the Tiger is shown in the distance with its barrel pointing straight forward. In the next shot, the turret is facing the fleeing soldiers again.
Continuity mistake: In the scene when Kelly is shown the Oddball's tank for the very first time, the Sherman has a loudspeaker mounted on the right hand side of the turret. The loudspeaker is placed on the opposite side of the turret for the rest of the movie. Also as far as luggage and other external storage is concerned, this tank actually looks different in every scene.
Continuity mistake: When Kelly comes to make a proposition to Mulligan, the sun is on Mulligan's back. When both are in the shot from Kelly's view, both are in the sunlight. Then at the, "I need an authorisation" reverse shot, they are both in the shade, these 2 scenes are obviously shot at two very different times.
Continuity mistake: Two of the German SS Tank officers are walking together through the streets of Clairmont chatting. In the first scene with them, the officer on the left carries the rank of 'Obersturmführer,' denoted by his lapel badges, and the officer on the right has lapel badges showing him to have the rank of 'Sturmbannführer' (although both officers' shoulder badges show no correlating rank to their lapels). However, in the second scene with the same two officers still walking and chatting, the officer on the right has been demoted as he is now showing the rank of 'Untersturmführer.'
Continuity mistake: Big Joe gets out of his jeep, salutes Captain Maitland, and converses about the upcoming time off for the men. Behind Big Joe is one of his half tracks and he is on Maitland's right. The scene cuts and Maitland's "liberated" yacht is behind Big Joe and he is directly in front of Maitland.
Continuity mistake: Don Rickles is assembling the .30 calibre machine gun onto its tripod prior to the action in the French village. Neither he nor his co-gunner have any visible anmmunition. The scene changes, the comes back to the .30 calibre machine gun, which is set up on its tripod and is loaded with a belt of ammunition. Where did the ammunition come from?
