When the soldiers enter the German aid station, toward the end of the film, two I.V. bags are hanging on a modern I.V. pole in the background. During World War II, I.V. fluids were packaged in glass bottles. Plastic bags came into use in late 1960s.
After Wardaddy gets his order from the Colonel to "smash the guns and rescue my boys" Wardaddy briefs the other sergeants about the mission. Sergeant Miles says "Mount up fuck sticks" without moving his mouth.
After a mine disables Fury and Wardaddy tells the group, "It's an SS battalion", Grady throws his large metal wrench down into the mud. It makes a metallic "clank," as if was hitting cement. It should have made a "splat" or nothing at all.
There is no reason for the German soldier to fully open the hatch and gawk into the tank when they have the hand grenades ready. There is a very good reason to instead crack the hatch open just wide enough to shove in the grenades, to avoid getting shot by tank crew inside.
When the young tank Lt is briefing Wardaddy and the other Sargeants about going on a "flank guard mission and working for Capt Waggoner" he points on the map and says "were going North then meeting up with Baker company and together we'll take the town " Then he points to the northernmost point on the map and drags his finger south, contradicting everything he just said.
When the tank crew finds the hanging civilian bodies, Wardaddy translates the sign on the woman's body as "I am a coward. I won't fight in the war." The sign actually says "I won't let my children fight in the war." A few minutes later another body has the "coward" sign that Wardaddy translated earlier.
When Wardaddy is in the apartment with the two women, he shaves his face thoroughly. About an hour later, during the battle against the German tanks, and his face is unshaven, same as before he entered the apartment.
Just after the dialogue about "a lot more people gotta die", the four tanks travel in column, with their 50 cal. machine guns manned and pointing forward. In the next shot, the camera zooms in on Wardaddy. His 50 cal is unmanned and pointing backward.
As Fury pushes through the hedge into the field where the infantry are pinned down, Wardaddy's goggles are on, protecting his eyes. Seconds later, as they are about to start shooting, the goggles are up over his steel helmet.
After the ambush by the 3 Hitler Youths, Wardaddy shoots the first soldier. He clearly falls on his right side, but he is revealed on his back. When WarDaddy shoots the other two Hitler youths, they fall about 5 feet from each other. When revealed they're lying right next to each other.
After Wardaddy captures the town and tells the mayor to have all the German soldiers come out with their hands up, a young SS officer exits the building holding up a piece of paper in his right hand. When Angel shoots him, he falls backwards and lands on his back. In the first camera shot, a piece of paper at his feet. In the next shot the paper is above his head.
During the flanking fight between Fury and the Tiger tank, the Tiger's turret turns past the 3 o' clock position towards the 6 o'clock position. When viewed from Fury's gun sight, the turret briefly goes back to the 3 o'clock position.
When the tank column leaves camp, Wardaddy, Grady and Bible talk are on the top turret, discussing whether or not "Jesus loves Hitler". Wardaddy's goggles go from tilted on his helmet to straight several times.
In the battle against the Tiger tank, the Fury crew of has to maneuver in order to penetrate the Tiger's weaker rear armor. Fury has an upgraded 76mm high-velocity gun, not the standard 75mm gun. At the range shown in the film, the 76mm gun could have penetrated the Tiger's frontal armor without issue.
Both the US and German tank crews fire while driving their tanks. While firing while driving was sometimes necessary, both sides would train their crews to fire the cannon only when stationary. Bumping from the terrain could cause the cannon to lift or lower by inches, sending the shot possibly miles off the intended target.
A penetrating Panzerfaust hit in the fighting compartment would have been universally fatal for all crew inside the tank, not just for a single crew member who happened to be in the way of the molten metal spray.
When Wardaddy returns to camp at the beginning, a pan shot shows a black soldier in a group. Later, another black soldier is sent to make contact with Wardaddy. The Army had limited integration in Europe after the Battle of the Bulge, but it didn't fully integrate until after WWII. The vast majority of black soldiers served in segregated units with white officers. A black soldier would have been a very unlikely choice for a messenger.
The Panzerfaust warhead was a shaped charge, driven by an explosive. Depending on the type, it contained roughly two to four times as much explosive than a hand grenade. On impact, it made a very loud bang.
When Fury and the Tiger are trying to outmaneuver each other for firing position, the Tiger gets a shot on Fury's flank that is deflected by the logs on Fury's side. In reality, the logs were mostly useful as protection from shaped-charge weapons like the Panzerfaust. An 88mm shell, especially when fired from such close range, would have shredded the logs, punched through Fury's side armor like it was tinfoil, and probably continued right through the tank and out the other side.
In the opening scene when Fury's crew first gets the tank rolling, Wardaddy calls, "Bible, gun front." The camera cuts to Bible with a "Roger," then Coon-ass, then Gordo, then five hanging Nazi medals. The last metal shown is the Cross of Honor of the German Mother, given to German women who'd had 6 or more children (the gold version was for 8 or more children). The tank crew wouldn't have found it on a soldier, and likely would not have it proudly displayed if they'd taken it off a civilian woman.
The Fury is an upgraded M4 using the same high-velocity 76mm as was on the Hellcat Tank destroyer. This gun could penetrate 120mm (Tiger's max frontal) armor at 1000 Yards with standard AP. at 1500 yards they could penetrate the 80mm max Tiger side armor. The tank charge was done early and mid war as the short 75 didn't have the same punch.
The tracks on Fury weigh more than two tons each. The crew would've known it was futile to try to fix a badly-broken track, with hand tools, in the middle of nowhere. Fury's extra tread links are from the earlier-model Shermans, with completely different tracks. Tankers didn't generally carry the extra track plates to fix broken tracks; they were usually welded on as an extra layer of armor.
Ellison says he's only been in the Army for eight weeks. In 1944, Army basic training was 12 weeks. He could not have gone through basic training, additional specialty training (even as a clerk typist), taken leave (which soldiers were granted after training) and deployed to Europe in just eight weeks.
Although Wardaddy wears the rank insignia of a Staff Sergeant (three stripes and a rocker) on his jacket, his veteran crewmen refer to him as "Top" several times. "Top" is short for "Top Kick," a nickname for First Sergeant (three stripes, three rockers, and a diamond in the middle), several ranks above Staff Sergeant.
After the tank column is ambushed, the lead tank is engulfed in flames and Wardaddy slaps Norman for "not taking the shot." All tanks would be loaded with gas and ammunition, and they should have been afraid of the ammo on the lead tank "Cooking off" or exploding.
Many scenes showing the back of the Sherman tank include a large cardboard box with black lettering and markings. It's supposed to be be Army meal rations, which came in wooden crates during WWII. The smaller, individual meals were packed in cardboard boxes inside the wooded crate.
One scene where the SS are using the Panzerfaust at close range and the effect of it is that it travels straight through the tank. This is not the effect of a shape-charge projectile. Though impressive in armor penetration at its optimal range, the effect of it is very localized.
The Tiger seems unharmed until it gets penetrated in the engine compartment. For some reason it keeps driving forth and back despite the fact that Fury is trying to get around it. The commander clearly points out they should not be allowed to get behind them; despite this fact the Tiger doesn't seem to turn at all in an attempt to keep the front armor towards Fury.
Sgt. Collier calls white phosphorus munitions "Willie Pete." The American Joint Army/Navy Phonetic Alphabet was a radio alphabet developed in 1941 and used during WWII. White Phosphorus could have been referred to as WP or "William Peter", hence "Willie Pete".
Brad Pitt's and Jon Bernthal's haircuts are the typical "Landsertolle" of the German infantry. However, many troops who spent a lot of time in combat or on the front lines went weeks without shaving or getting their hair cut, and the army didn't get too particular about it.
Fury is immobilized by a land mine in the middle of the road. However, to both parties it would be impractical to plant a land mine in that area, as the Allies were sending a tank company to take over the crossroads and the Axis had an SS battalion passing through. Both parties could trigger the land mine.
Set in April 1945, but the vegetation is too advanced for April. When Norman is sent out to scout at the crossroads, he crouches among English ivy, which is in flower next to his head. English ivy doesn't flower until late summer or fall.
At the beginning of the battle with the Tiger I tank, Don calls for a Smoke round to be fired. Grady grabs an M93 Hypervelocity Armour-Piercing Tracer Solid Shot (HVAP-T M93). Nicknamed "hyper-shot" by tank crews, it was intended to be a tank-killer. Grady loads the round and yells "Smoke's up!" Boyd fires in front of the Tiger I, revealing a cloud of white smoke. A White Phosphorus (WP T13E2) smoke round is just below and to the right of the HVAP-T round that Grady grabs.
The goof items below may give away important plot points.
When the enemy battalion marches by Norman before the final fight, at least five Germans hold Panzerschrecks. However, no Panzerschrecks are used until most of the battalion has been killed, and they were taken out of a box.
During the last battle scene, Boyd runs out of ammo for his Thompson sub machine gun and exits the tank to find another weapon. When he leaves, he's covered in mud from head to toe. When he falls back into the tank after being shot by a sniper, he's relatively clean.
At the end, when Norman is driven away in an Army ambulance, he looks straight out the back of the ambulance and sees the full right side of Fury sitting in a crossroad. When the camera pulls away from Fury in an aerial view, the tank is not sitting in a crossroad.
An SS man drops two M24 "stick" grenades into Fury. They detonate after Norman escapes through the bottom hatch. When he returns to the interior of the tank, Don Collier's body is completely intact and unaffected by the blasts. M24s are fragmentation grenades, the detonation of high explosives and flying shrapnel within a confined space would cause serious damage to everything inside, including the bodies of the tank crew.
In one Town scene, a helicon (brass instrument related to the tuba) is next to a booby-trapped piano. Toward the end of the war, the Third Reich experienced shortages of refined metal. Thousands of brass instruments were confiscated and melted down for bullet casings. It's very unlikely that the helicon would have escaped.
After Norman goes out as an outpost guard, he returns to the tank and tells the others about the approaching SS battalion. They all hear them coming. They spend 30 minutes deciding whether to stay, prepare for the defense, and chattering. A battalion audible from that distance would've reached them before they entered the tank.
The German column in the fight at the end consist mostly of troops on foot but also has several vehicles. They would of course send at least one small group scouting ahead in one of the vehicles, like the armored half-track, precisely to avoid running into an ambush like that.
