Anachronisms: There's several scenes of Japanese Mitsubishi A6M2 'Zero' fighter planes strafing Chinese civilians and Nationalist soldiers in 1937-38. The Mitsubishi A6M2 Zero fighter plane would make its combat debut over Chungking, China in August 1940. Prior to that time, the Japanese were employing imperial Army Nakajima Ki-27 fighter planes with the fixed landing gear and the imperial Navy Mitsubishi A5M, also with fixed landing gear, later codenamed, "Claude", by the Allies. The Allies later codenamed the Ki-27, "Nate".
