Other mistake: When Stryker is killed at the end, it shows him lying on his back. Then, it cuts to a shot that shows the name on the back of his uniform. Who turned him over? (01:48:06)
Factual error: After being under bombardment for several days, don't you think it was polite of the Japanese to shave and put on clean uniforms for the invasion?
Continuity mistake: As John Wayne leaves the landing craft he loads a stripper clip into his bolt action 1903 Springfield rifle. A minute later his rifle has changed into an M-1 Garand.
Factual error: During the scene where Stryker is fighting with Forrest Tucker, an officers staff car pulls up. The car appears to be a 1946 or later Dodge or Plymouth, which was not yet manufactured.
