Factual error: During the movie Tom Skerritt is seen talking to the SEAL team from the carrier's flight deck. That's impossible; command & control operations are being performed from the inside of the ship. Besides, roar on the flight deck would be so loud making it impossible to hear each other.
Continuity mistake: In the overhead scene of the first village, after the rebels had slaughtered all the remaining people, all the people strewn across the street are completely clean, no gunshot wounds, no blood, no gore or anything. Also in the same scene, the people that stayed behind (exceptions being the two nuns and the priest) had been so severely injured that they were unable to walk, so how did they miraculously heal themselves after they were attacked?
Factual error: At the end of the movie when Willis calls in the F-18s for an air strike we see them engage the rebels by firing a couple of AIM-120 AMRAAM missiles at the ground. This is wrong because an AIM-120 is a air to air missile only. The warhead on the missile is only a few pounds and doesn't produce the cluster munitions like effect that they show. It would have made more sense if the 18s would have dropped a couple of CBU's (Cluster Bomb Units) instead.
Continuity mistake: At the end of the movie, when Lt A.K. Waters and Dr Lena Hendricks are in the helicopter awaiting take off, he is sitting on her left and rests his head on her left shoulder. However, in the next shot as the helicopter takes off, he is sitting on her right side.
Continuity mistake: When the refugees cross a river Dr. Kendricks is carrying a little child. The child is facing away from her, with its right arm around her neck. When the camera angle changes she is holding the child face-to-face, and now its left arm is around her neck. Then a soldier takes the child from her while it is facing away from him, but when the camera angle changes again the child is turned around and facing him.
Continuity mistake: During the rebels' first major attack on the fleeing party, there is a lull in the fighting where Lt. Waters runs to find out whether Lena Kendricks is okay. When he reaches her, he lifts her up and she places her right hand against her ear. However, during different shots in this scene as he is talking to her, her hand goes from being next to her ear to not being there, several times.
Continuity mistake: If you watch the air support coming in to bomb the enemy troops from the time they take off to the time they leave, their load out varies a number of times. Watch as they approach for their bombing run - the weapons switch from white finned missiles to yellow-tipped green bombs and back before being fired.
Other mistake: When the Navy SEAL snipers start shooting at the ethnic cleansers, there are two snipers, the sniper that shoots second (he has an M-14) hits a Nigerian soldier in the back, they then go back to the sniper in the tree who tells Dr Kendrick to be quiet by. They then go back to the second sniper and he shoots again they show the same shot of the Nigerian getting hit in the back but from a different angle.
Continuity mistake: When Bruce Willis is on the phone with Tom Skerritt, Skerritt is holding the phone with his right hand and the antenna pointing up. In his next shot we see him with the phone in his left hand and antenna pointing down. So he could have changed hands but it doesn't seem very likely.
Plot hole: After the team takes care of the ethnic cleansers, there is a flat-bed lorry with a belt-fed weapon just sitting there. Since the cleansers came in from somewhere ahead of the team, why not load the refugees onto the truck and head out? If nothing else, it would increase their lead over the pursuers.
Factual error: The SEAL team communicates with the commander on the ship with a man pack VHF/UHF radio. Not only does the radio man not erect the antenna but it would not be possible to communicate with the ship using this type of radio because it is a "line of sight" radio designed for ground to air communication. The commander on the ship uses a satellite phone to respond, it is not possible to use this type of radio to communicate with a satellite phone. Also, the Lieutenant doesn't use the push to talk button on the side of the microphone and uses the radio more like a telephone, the equipment simply doesn't work that way. The time is from the director's extended cut.
