Factual error: During the final battle, Gordo the tank driver calls out, "Panzerfaust, four o'clock!", as he looks through his periscope. He could not have seen any targets at four o'clock, as the driver's periscope could barely rotate towards the eleven and one o'clock positions, close to the left and right front corners of the tank's hull. The four o'clock position would be near the right rear of the tank.

Factual error: Chris Kyle did not make Chief after his first deployment. He made Chief during his fourth deployment.

Revealing mistake: In the scene where Themistocles first talks to Queen Gorgo, in the background you can see several extras, one of which is wearing obvious sneakers. (00:18:35)

Factual error: The three panzers that ambushed the Hellcats are supposed to be Mk. III's with the 50mm gun, but they only had 5 bogie wheels, instead of 6, and no driver or radio operator's hatches.

Factual error: When the Germans come to the town a tank rolls through the picture. The first shot shows the tracks, then the whole tank is shown and one can see the tracks again. The turret suggests a Panzer III (which would be accurate for the time). It appears however that the tank is a modified Russian T34 or T55 or something as the road wheels are too big for a Panzer III. (00:13:00)
Character mistake: When the supply convoy is ambushed, Soto is instructed to get on the .50 caliber. However, the weapon on the gun ring is a .30 caliber M1919 machine gun, not a "Ma Deuce" .50 caliber.
