Corrected entry: In the scene where the ATP is ambushed by the two groups of Americans we see Cpt. Miller take their right flank and kill three Germans trying to run for it. But watch as he shoots. The second he stops shooting an explosion goes off in the background 20 yards away. This can't happen with the gun he's firing (Thompson) because it doesn't shoot explosive rounds. In addition to the shooting, a German messed up by getting shot way after Cpt. Miller stopped shooting.
Corrected entry: When the Waffen SS unit attacks the town at the end of the film (Ramelle), the Germans use "allied" tactics such as crowding behind a tank to enter the center of the town at a disadvantage by the tall buildings and rubble that inhibits quick forward thrusts. At this stage of the war, especially Waffen SS units (even if they may be replacement units - which I doubt) they would not be blindly led in such horrific maneuvers.
Corrected entry: When Mellish's gun gets jammed he doesn't fix his gun or do anything to it. When the Germans kill the Airborne soldier through the wall, they try to enter the room and Mellish shoots another shot, killing the first German.
Corrected entry: In Neuville just after Miller's group joined the other scattered soldiers, they try to get to the other side of the city. One of them tears down a wall with Germans hiding in the building. After screaming at each other, the Germans all get shot by others from above. Some moments after this shootout, you hear this very distinctive M1 Garand "pling" sound. This sound only is to be heard after the last shot has been fired and the clip is ejected automatically. Bang - pling. But in this scene there is no shot. If you unload manually, the pling will not sound.
Corrected entry: After the taking of the beaches, and Miller returns for revised orders, the fleet in the background appears/disappears.
Corrected entry: In the scene in the Pentagon between several officers and General Marshall, when the camera pans over Marshall's left shoulder towards the officers, you can see that the colonel, who was missing his left arm in earlier scenes, has it again; it's missing again in the next shot. It may be just that his sleeve's rolled down in the middle shot, but that's still an error.
Corrected entry: In the Ryan farmhouse scene, the camera pans across the room. You see a telephone hanging on the wall. That type of phone did not appear until at least the 1950s.
Corrected entry: When they exit the beach and attack the big concrete bunker two grenades are thrown at the entrance some distance away but the explosion happens on the other side of the wall and not near the entrance at all.
Corrected entry: During the climatic battle scene near the end, a Marder III tank destroyer is driven into the city and gets destroyed by American soldiers with molotovs. However, a Marder III would never be driven into a city as a vanguard with such high ambush possibility, as it was a vehicle solely dedicated for anti-tank purposes and would be hopeless against infantry.Yue Hin Yeung
Corrected entry: When inside the higgins boats, we see some men have netted helmets. However when they started to get blown to bits, they all have regular helmets.
Corrected entry: When Jackson is firing on the Hetzer, the Hetzer eventually silences Jackson with its main gun. The vertical elevation for the Hetzer was no more than 30°, much too low to hit Jackson in the tower.
Corrected entry: When the planes fly in to the rescue at the end of the movie, Miller refers to them as being part of the Air Force. The Air Force was not established until after WWII. During WWII it was the Army Air Corps.
Corrected entry: Throughout the movie Pvt. Jackson uses a Springfield '03 rifle; a rifle that can only hold 5 rounds of ammo at a time. In the final battle scene where he is firing on the Germans from atop the church tower, you see that he fires more than 5 rounds continuously without reloading.
Corrected entry: When Miller arrives at the bottom of the hill, under the German machine gun, there's a radioman to his left. This soldier gets his face shot off, but in a later beach scene, he appears as a different wounded soldier.
Corrected entry: Upham is referred to throughout the film as a Corporal. He is actually a Technician 5th Grade, indicated by the 'T' beneath his stripes. The same pay grade, but without the NCO rank. This doesn't stand for "Translater" as some people have argued - "Technician" was a term applied to anyone with a special skill - the US Army now uses "Specialist" instead to avoid confusion.
