Other mistake: When they are lifting the boxes of gold at the end of the movie you can tell that the boxes are empty.
Other mistake: When Telly Savalas drives into the farmhouse he leaves the chaplain in the jeep which is approx. 50 feet from where Clint Eastwood and the rest of the soldiers are planning to steal the gold. For about five minutes they are arguing quite loudly about if it is a good idea and afterwards they then agree to the heist and they all crowd around the map and are extremely jubilant. Is the chaplain still sitting in the jeep listening to all this? We never see him again. (00:38:15)
Suggested correction: This isn't a mistake; at best it's an unresolved plot point. The chaplain became irrelevant to the plot at that point so their story line ended without explanation. If anything it makes it more realistic.
Other mistake: During the battle at the bridge, Kelly asks Oddball about the other Shermans. Oddball replies, "No man, they've both had it. One is in the river and the other is on the other side burning." Soon afterwards we see Big Joe and Cowboy arguing with Bellamy about staying behind to fix the bridge, while crouched beside a Sherman. This is obviously not Oddball's Sherman as Big Joe and Cowboy are on the opposite side of the river, therefore it must be the one that Oddball said was burning. However, no right-minded soldier (or anyone else) would crouch next to a burning Sherman.
