Continuity: When Rambo is escaping with the POWs in the helicopter, one of the POWs clearly machine guns the Russian helicopter and one of its rocket pods falls off and into a tree near a house, yet in the next scene it's back on.

Factual error: When the close up of the engine for the plane to drop Rambo off is shown starting up, in the next shot a voice can be heard saying "APU start". The APU starts the engine, so the engine couldn't have been started first.

Revealing: Towards the end of the movie, when Rambo is setting everything afire with his exploding arrows, an enemy soldier stumbles through a patch of tall burning grass. As he falls to the ground covered in flames, the fireproof mittens the stuntman is wearing are visible.

Continuity: In the POW camp, Co Bao is discovered by a guard who points a handgun at her. Rambo shoots an arrow into the guard's forehead, who then falls back against a tree with his cap down low over his eyes. In the next shot his cap is much higher on his head, and the arrow is pointing at a different angle. How could his cap have moved up that far with the arrow holding it to his forehead? For that matter, how could the arrow have moved when it was firmly embedded in the guard's skull?
