Revealing mistakes: Angel Salazar's video camera, as shown in the opening scene, is a small, cheap camcorder. However, during the scene where Master Sergeant Sweet is introduced, the camera's shadow suggests a much larger high-end HD camera with wide lens and external microphone is being used.
Factual errors: At the military checkpoint scene, U.S. Army soldiers are seen with a Challenger tank. The U.S. Army does not use the Challenger tank.
Revealing mistakes: In one scene, PFC Angel Salazar is seen wearing his rank insignia upside down on his uniform.
