Continuity mistake: Wardaddy raises his cigarette lighter to his cigarette twice while he speaks to Norman after the town has been taken. (00:51:30)
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: Chris Kyle did not make Chief after his first deployment. He made Chief during his fourth deployment.
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.
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)
Revealing mistake: While trying to out-run the Panzer at the end, the Panzer crew is with foliage surrounding them upon the tank. Yet not a single leaf is blowing in the wind despite being at near top speed. (01:12:00)
Factual error: During the Hungnam evacuation scene in December 1950, a U.S. Army Captain is using a radio handset. The model he uses is the H-250, which was introduced in 1987, over 30 years after the Korean War.
