Continuity: Rambo has a cut on his left cheek bone that is forever getting smaller, bigger, scabby and in some scenes it's gone. Sometimes it's white, sometimes red. This all happens in one day.

Continuity: The soviet military equipment isn't all that Soviet ... e.g. the helicopter is supposed to be a "Mil-Mi 24 Hind" (Pilot and system operator sitting behind each other), in fact it's just a French "aerospatiale puma" with additional mock turrets and so on (crew sits side by side).

Plot hole: After Rambo crash lands the helicopter, he and his colonel buddy start heading north-east. The Russians start heading south-east and yet they manage to run into one another.
