Corrected entry: In multiple jungle scenes when the Rangers are shooting their automatic weapons at each other, you can distinctly hear the ringing sound of shell casings falling onto a hard (concrete) surface.
Corrected entry: At the end of the movie it is revealed that Section 8 knew about the Colonel, Kendall, Mueller and the doctor and pretty much everything about the drug operation. Why then did they need this elaborate plan to pretend that West was shot? Who did they really flush out if they knew all the parties involved? In the end all the parties involved except the doctor were killed. If they wanted to do this they could have just killed them. Dunbar already knew where the drugs were so that was not in question. Plus because Dunbar runs off with Travolta, this would likely spark a massive investigation.
Corrected entry: A soldier under suspicion of killing fellow soldiers would have his filed reviewed and such file would indicate that he was black and not white which would make it implausible that Pike could sit there and pretend to be Dunbar with no one figuring it out until the end.
Corrected entry: The Rangers throughout the movie are using the standard M16-A2 rifles with an undermounted M203 grenade launcher. In several scenes they are shooting automatic (continual) fire. This is a characteristic of the older M16-A1 rifle. An M16-A2 doesn't have an automatic setting. It fires either one shot at a time (semi-automatic) or in 3-round bursts.
Corrected entry: If both Pike and Dunbar are in training with other Rangers, then how could Pike possibly pretend to be Dunbar after he returns to base? Wouldn't someone have identified him as Pike before the doctor does?
Corrected entry: The members sitting around the table at the end claim to be the Secret "8" group who have been trying to take down the bad drug guys - including Giovanni Ribisi. However, Dunbar and Ribisi both write the secret 8, and although Dunbar is a part of the "8" group, Ribisi should not be.
