During the courtroom scenes the bruises on Col. Childers' face from his fight with Col. Hodges move around. For example, when the verdict is read Col. Childers has a crescent shaped bruise under his eye and a cut or split in his lip. However, when he emerges from the courtroom following the verdict, the crescent shaped bruise is gone and there is no noticeable injury to his lip.
When the Marines board the helicopters on the aircraft carrier, they are initially CH-46 Sea Knights, a twin rotor Marine helicopter with three landing gear. However, all the subsequent shots show the much larger CH-47 Chinook with four landing gear.
When Col. Childers boards the helicopter on the USS Wake Island, it is a USMC UH-1N Huey with twin engines. During the shots of the helicopters approaching the embassy, Childers' helicopter switched to a UH-1H Huey with a single engine. The helicopters in the shots of the Wake Island were actual Marine Corps aircraft, two CH-46 Sea Knights and the UH-1N Huey. Later shots were helicopters belonging to the Moroccan Air Force, two CH-47 Chinooks and a UH-1H Huey, which were painted to look like the USMC helicopters.
In the opening scene where Hodges' platoon is pinned down by Vietnamese fire; as Hodges is leaning over to his radioman to respond to Childers first call on the radio, his front left magazine pouch changes from open to closed between shots.
Along with using two different types of helicopters for the take off from the ship to the insertion into the embassy, there are two totally different squadrons used for during the time which would take only a few hours. On the ship, when the Marines are boarding the aircraft, the side of the aircraft reads what squadron that aircraft belongs to which, on the ship scene it is HMM-764, a reserve squadron based out of Edwards Air Force Base in CA. When the Marines get dropped off at the Embassy the squadron on the aircraft reads HMM-268, a active squadron out of Camp Pendleton.
In the scene where Col. Childers is approaching the entry to the base where an angry crowd of protesters and reporters awaits him, his drivers side window is clearly closed. The next second he encounters the crowd the window is suddenly open, proven when one of the protesters spits on his uniform and he gets out of the car grabbing the protester by the collar and slamming him into the car.
During the fight between Hodges and Childers, just after Hodges throws the pillow and knocks Childers to the floor, you see someone from the crew slide across from right to left, pick up the pillow, and toss it to Childers.
In the beginning southeast Asia scenes, the forest contains large old-growth trees with thick, heavy bark, south-facing moss, and large broken logs. This type of forest structure is indicative of old-growth northwestern United States forest and is not found in Vietnam, where tropical forest layers compete for available sunlight. In tropical forests, the trees have thin, whitish and tall canopies with hanging vines and even moss layering. Also of note are the ground palms which are too uniformly planted and the lack of thick dead ground mulch found in tropical forests.
Several strange things about the inability of anyone to testify that the crowd was armed and hostile. First, Colonel Childers' initial orders were to engage hostile targets, to which Red Six replied that there were women and children in the line-of-fire (tacitly admitting that there were hostile targets). Childers' reply was to question whether or not Red Six heard the order. Red Six requests clarification, asking if he is to fire into the crowd, and Childers replies "Yes, Goddamn it!" This exchange was taped and used in the trial. The problem is that Red Six is the one who first mentions the crowd, in direct response to Childers' order to engage hostile targets. By inference, he stated that there were hostile targets in the crowd.
