Audio problem: After Rambo turns onto the dirt and rock road, it looks like he is shifting gears, but the sound of the engine doesn't match.
Continuity mistake: When the truck crashes through the police road block, you can see the tailgate coming down. At the gas station, however, it's up again and Rambo has to lower it to get the M60.
Continuity mistake: During the car chase, after Rambo escapes from the jail, the hub caps on the sheriff's car keep appearing and disappearing. The passenger rear and one on the driver's side even pops off, but reappears again. Look closely after the car flips over.
Factual error: The state police cars have light bars that show blue on the left and red on the right. In real life, the light bars would be red on the left and blue on the right.
Continuity mistake: In the initial scene with Col. Trautman, we see the Sheriff wearing a lightweight jacket. Then, miraculously he's wearing a sheepskin coat.
Suggested correction: Teasle has his wounds cleaned while wearing his sheepskin coat over the undershirt (he removed his dirty uniform shirt/jacket). When the deputy enters with the maps Teasle has put on a clean uniform shirt while offscreen, then puts on his Sheriff's uniform jacket, which he wears when Trautman says Rambo was the best. It cuts to Rambo killing a wild boar and carrying the carcass to his hideout. Then Teasle wears the sheepskin coat over his uniform jacket, which he put on while offscreen.
Revealing mistake: Towards the end of the film where Rambo shoots up the computers in a building and the spent rounds are falling to the ground. It is clear to see that these are blank rounds. Where the bullet would sit in the case normally you can see the case is extended, This is where on a blank it is just crimped closed due to the lack of a bullet.
Continuity mistake: When Rambo throws the soldier out of the truck and has a dog fight with the state police vehicle his shoes are shown on the accelerator pedal. Those are shoes, not the genuine army boots he wears in the rest of the movie.
Audio problem: In the shot early on, where Teasel jumps his car and breaks a fence post, his car horn beeps when the car lands on the ground. A few shots later, when his car falls down, then flips over on the embankment, the car horn gets stuck. It's a totally different car horn sound this time.
Continuity mistake: When Rambo has Teasle up against the tree with the knife, it is under Teasle's throat, but in the next shot the knife is to Teasle's right without Rambo moving it.
Continuity mistake: When Rambo jumps the fence on the motorbike, Will follows in the car but look at the rear wheels of the car they are bigger and wider with no hub caps because of the rough ground when there back on the dirt road the rear wheels are normal with hub caps.
Continuity mistake: After jumping off the dirt road chasing Rambo, the sheriff's right rear wheel has the hubcap on after landing. A second later, it's missing.
Continuity mistake: During the motorcycle chase, just after the police car breaks through the wooden gate, in the close up of Rambo's motorbike its wheels go through two puddles, a short space of land, then another puddle. Keep watching closely as he rides through the mud. In the overhead shot of Rambo approaching the road at an intersection, he goes through the same three puddles again (the third one is hidden behind a tree, but you can still see the splash).
