Visible crew/equipment: Near the end of the movie when the convoy is heading back to the Pakistan Stadium, a Humvee stops briefly to allow a man to walk across the street with a child in his arms. When the shot changes and the Humvee begins driving again, a crew member or cameraman is seen inside the Humvee wearing a white shirt. All of the men who entered the Humvee were wearing fatigues.
Continuity mistake: In the scene where Star 41 is called to the first crash site, it has mini guns and rockets, but when it gets to the site it has seats for people.
Deliberate mistake: When Blackburn reports for duty, he is asked his "Serial Number" and reels off some 7 digit number. However, in '93 and earlier, the Army was already using the Social Security Number (9 digits) for your Service Number (it's not called a Serial Number).
Continuity mistake: Just before Sgt. Eversman rappels down from the helicopter at the beginning of the raid you can see that he is not wearing kneepads. On the way down the rope he is wearing them. Once he is on the ground the kneepads are gone again.
Visible crew/equipment: In the scene where the armored convoy jeeps fire at the roofs as the they drive down the street, when they show the two kids firing guns then getting shot down, look to the right at the pile of rocks that "explode" and you can see the wire used to knock them out of place.
Visible crew/equipment: During the scene after the soldier falls out of the helicopter, an intense gun battle breaks out. As the troops rally to evacuate the injured man, another soldier lays down some suppressing fire. Look in the lower left corner of the screen. Two crew members, one wearing eye protection and one wearing ear protection, are visible.
Audio problem: when Gordon and Shughart go to the 2nd crash site and Gordon knocks on Durants cockpit door, he asks him 'how bad' then fires his rifle. The problem is that 2 cartridges are ejected but there is only one shot heard.
Continuity mistake: When the Humvees and the trucks pull up to get the prisoners, there is a shot of a man shooting an M60 on top of a Humvee. In the next shot it reveals all the guns on the Humvees are .50 caliber.
Character mistake: Early in the movie when Pilla is making fun of CPT Steele, he is referred to as 'Specialist' (E-4) by CPT Steele right before CPT Steele puts him in the headlock. However, later in the movie when he is shot while up in the turret, SGT Strucker refers to him as 'Sergeant' Pilla (E-5). E-5/SGT is denoted by 3 chevrons on the collar and E-4/SPC is denoted by the rank seen on his collar during his scene with CPT Steele.
Factual error: In the background of the scene involving CPT Steele giving SGT Eversmann charge of the Chalk 4, is a transport plane bearing the tail number of a Moroccan civilian plane (CN-ANG). Morocco was not a combatant in Operation Gothic Serpent.
Revealing mistake: During the Humvee convoy's dash to the first crash site, a quick, far-overhead shot shows the column racing down a dusty street, kicking up an obviously CGI trail of dust. The dust billows up from the Hummers, but travels in the opposite direction far faster than the ground below, almost as if a very strong wind is blowing in the opposite direction of the convoy's travel, but everything else in the shot shows the air to be calm.
Factual error: The medic working on Jamie (the ranger with the femoral artery wound) is a delta named Schmid (from BHD the book). But in the movie, the guy's wearing green armor and has hair only on the top of his head - both typical of a ranger and not a delta. [Little known fact (far from OPSEC), but prior to deployment, all the Delta guys got high and tight haircuts. I was in 2-14 Infantry (part of 10th Mountain Division) during that timeframe.]
Continuity mistake: When the original leader for Chalk Four runs and sits down in front of the TV back at the base to watch the Steve Martin movie, the Jerk, he has a remote control in his right hand. As he has his seizure and falls with the remote control in his hand, subsequent scenes show it is not in his hand, then it is.
Factual error: In the movie, the Rangers and Delta operators defending the crash site are engaged by several 'technicals' (pick-up trucks with crew served weapons mounted) including one with a recoilless rifle directed by the Somali 'head honcho'. Also, several technicals seem to (somewhat implausibly) spring from the woodwork as they flee the city on foot... However, during the entire course of the actual battle, there was never a SINGLE mention of the pinned down forces being engaged by such vehicles and the Rambo-style capture of the recoilless rifle was a comical fabrication.
