I liked the USAF chevrons on a couple of guys in one of the scenes. It wouldn't be for another 4+ years after June 1943 that the USAF became a separate service. The animation is well done, but the factual stuff leaves a bit to be desired.
Completely agreed, a hard work of 3D animation ruined by poor knowledges in armament, aviation and history, even the swastika in the robot shoulder is wrong.
