Corrected entry: After losing the motorcycle climbing the mountain, Rambo searches through abandoned mining equipment for survival items. He finds an old tarp from which to make a poncho. When he takes out his survival knife he throws away the scabbard. The scabbard is back on his belt for the rest of the film.
Corrected entry: This movie occurs somewhere in the extreme NW. We know this because when the sheriff drops off Rambo after giving him a ride at the beginning, he says that Seattle is due south. Why then do so many of the characters talk with southern accents? The fat deputy and the hound handler are the 2 most noticeable, but there are many. Even accounting for immigration, this seems to be a mistake by the director. It's probably meant to be in a stereotypical hillbilly backwater town, with the accents confirming this, but inexplicably it's the Canadian border.
Corrected entry: At the beginning, Rambo goes into town to visit someone he served with in Vietnam named Delmar Berry. Rambo shows his wife a picture of the "Baker Team" back in Vietnam and lists the people in the picture, including the names Westmore and Bronson. When Colonel Trautman is trying to contact Rambo on the radio, he identifies the "Baker Team" and reads off a list of names that doesn't include Westmore or Bronson.
Corrected entry: When Rambo goes berserk in the downstairs jail of the Sheriff's office, he systematically pummels each of the 4 or 5 officers before making his escape. Since when is it police code to not be armed in the presence of violent prisoners? If even only one of the officers were armed, Rambo would have been taken out in 2 seconds. This inconsistency is especially glaring since these officers were backwater yokels who probably did not follow any code of ethics, considering they were practically torturing Rambo down there.
