Factual error: During the final battle, Gordo the tank driver calls out, "Panzerfaust, four o'clock!", as he looks through his periscope. He could not have seen any targets at four o'clock, as the driver's periscope could barely rotate towards the eleven and one o'clock positions, close to the left and right front corners of the tank's hull. The four o'clock position would be near the right rear of the tank.
Factual error: In the hedgerow battle, the Fury tank platoon face off with a German MG 42 machine gun and two 7.5 cm Pak 40 anti-tank gun. Each of these guns opens fire only after the previous one gets knocked out. In a real combat situation, all of the guns would open fire at the same time and establish a cross fire, effectively suppressing the ground troops and tanks from advancing. (00:31:35 - 00:33:30)
Factual error: Wardaddy orders Grady to load a smoke shell to blind the Tiger. But Grady takes a shell labelled "HVAP-T M93", which is a high-velocity armor-piecing round from the shelf. When the shell is fired and hit the Tiger, it shows a smoke effect rather than an AP effect. (01:19:20)
Factual error: One scene has Sgt. Collier having a conversation with Norman as they are riding on the turret of "Fury" without their tank intercom throat mikes and headphones. The noise of the moving tank alone would cause any conversation to be a shouting match between the two soldiers. Further, they are in column with three other noisy tanks, which would make a casual conversation even more difficult without utilizing their tank intercom system.
Factual error: In 1945 the Model 24 "potato mashers" thrown inside the tank in the end of the movie could not be blast effect grenades, but fragmentation ones used from 1942. Also the TNT used in them would have exploded at almost the same time and not in two separated booms as heard. And the devastation inside the tank would have been much worse. (01:59:00)
Factual error: When Fury enters a village and faces a field gun attack, Sgt. Collier orders through the tank radio "Throw some Willie Pete in that ground floor." While white phosphorus has been used for a century, Willie Pete as a slang term for it only dates from the Vietnam War. (00:48:05)
Factual error: The film shows the American and German tanks firing at each other on the move. Tank warfare doctrine dictated that tanks must be stationary when shooting at a target, to ensure a hit. Some tanks were equipped with stabilizers on their guns to allow firing on the move. All the tanks in "Fury" (German and American) were not so equipped.
