"She weighs one hundred fifty kilograms and fires two hundred dollar custom-tooled cartridges at 10,000 rounds per minute. It costs four hundred thousand dollars to fire this weapon, for twelve seconds."
Ever since Richard Gatling's 1861 invention, the rapid-firing rotary gun has had a special place among BFGs
. Because it's basically the gun equivalent of a chainsaw
, there is an undeniable attraction to a gun which can produce high enough rates of fire to cleanly trim hedges, cut down trees
, or, in the case of the GAU-8 Avenger
, saw tanks in half
The Gatling gun is likely to function as a significantly more powerful version of a regular machine gun, requiring hulking mountains of muscle to move them, or some kind of vehicle mount. If one gets used, you can expect it to give a nice steady buzz as it spews a constant stream of death.
Modern super-fast Gatling guns actually make a strange, deafening buzzing sound in the bass register (5000 tiny explosions per minute equals 83.3Hz, similar to the sound of a very large truck engine). Some of them, like the Phalanx anti-missile cannon, sound even weirder,
because they start at a lower rate of fire and then spin up to a higher one in distinct steps (in such designs they do not actually begin spinning the barrels until it fires the first shot and they require a moment to come up to speed), giving two or more separate "notes". Instead of a Dramatic Gun Cock
, the sign that a Gatling is preparing to fire tends to be the sound of it spinning up.

Anime & Manga
- A man with a Gatling gun killed several powerful villains (in fact, practically every villain besides himself) early on in Rurouni Kenshin. It was an era-appropriate early model, operated with a hand crank. In the anime, he was stopped when it jammed after one of the villains stuck a poison dart in the ammo bandoleer; in the manga he simply ran out of bullets after mowing everyone down.
- The problem with the aforementioned weapon in the manga is that it looks more like a British recoil-operated Maxim gun due to the incredibly obvious barrel jacket and ammunition belt. The supposed firing crank ought to be the cocking handle, Gatling guns were fed by gravity-operated hoppers, and no Gatling gun has ever needed to be water-cooled. And to add insult to injury, this "Gatling" (as stated, more likely a Maxim) has appeared about six years before it was invented. I think this villain should actually try reading English before purchasing weapons.
- Actually, the ammunition belt is the only problem. The earliest model Gatling guns did have their firing crank on the right side rather than behind, and they also did have barrel jackets along with a matting-type material packed around the barrels and soaked with water (this was removed in later models as it proved unnecessary).
- In Yu-Gi-Oh! 5Ds, Lotten, the Big Bad of the Crashtown Arc, uses Gatling Ogre, a Fiend with a Gatling gun in its chest, with which he can achieve a First Turn Kill.
- Fullmetal Alchemist: When Basque Grand transmutes an enormous arsenal of weapons, there's a Gatling gun somewhere in there.
- For a while, a Vulcan cannon was the primary "weapon" of Bungo Takano's "shadow dragon" Hainekuwele in Narutaru.
- Gundam features Gatlings all the time. The most prominent example is probably the Gundam Heavyarms. Aside from the Beam Gatling fitted on the arm, it also carries a pair hidden in its chest. Later in the series, it gets upgraded to a double beam Gatling. In Endless Waltz it was retconned into having two double Gatlings, and four in the chest.
- Almost every Gundam in the series has a pair of Vulcans fitted in the head- essentially much smaller Gatlings for shooting down aircraft and missiles.
- Macross (and Robotech) both feature Humongous Mecha scale Gatling cannons typically called Gunpods as their primary weapon for nearly all Valkyries, in various forms since inception. The Gatling cannons generally have a two inch bore.
- Gargomon in Digimon Tamers had a Gatling gun on both arms, making him dangerous to the humans as well as the Digimon early on — he was a bit drunk with the Champion level power.
- Zoids has the Hibilt Vulcan cannon, a massive six-barreled beam Gatling weapon. Oddly enough, the anime would often inconsistently depict it as a projectile weapon instead. There are too many Zoids that can equip it to list here, but we will mention Karl Shuvaltz in Chaotic Century, who was known for having all his Ace Custom units being armed with one.
- Guu has a Gatling gun arm.
- In episode 21 of Zettai Karen Children when Oboro Kashiwagi the otherwise ordinary secretary lays eyes on a life sized doll of herself, her response is to whip a minigun out of nowhere and shoot it to dust.
- Appleseed has large tanks that have stupidly large six-barreled rotary cannons in place of the main gun. And the monstrous mobile gun platforms have four of the same. Each.
- Chao's robot army in Mahou Sensei Negima! used these against Mahora's mage army. They were loaded with bullets that could send the victim into a future in which they'd already lost without any possible defense aside from dodging as a functional One-Hit Kill.
- In One Piece, new character "Blood Splatterer" Coriboo is seen wielding a hand-held crank-operated one. Probably how he got the nickname.
- His brother Caribou also carries one inside of him.
- One villain from Black Lagoon wields one in "The Hunt for Greenback Jane"/"Roanapur Freak Show".
- The first Rebuild of Evangelion movie featured Unit 01 with a huge gatling gun◊. Eva-scale. With spent casings that crush cars underneath them.
- The titular Exaxxion mecha from Cannon God Exaxxion subverts this by making a trio of 88 mm Gatling cannons the SMALLEST weapon on the entire mech.
- Milly Thompson of Trigun carries a semiautomatic version that fires expanding projectiles with enough force to knock over whatever they hit, including armored trucks.
- Monev the Gale uses a pair of wrist-mounted Gatlings powerful enough to tear through buildings, then switches to an even larger one that can destroy a bank vault.
- Magical Record Lyrical Nanoha Force has Arnage, whose Divider is a pair of Gatling guns strapped together which she easily wields with one hand◊.
- In Ghost in the Shell: Stand Alone Complex, Batou uses a Gatling in the style of "Ol' Painless" from Predator during an invasion of Section 9's headquarters by a military wet team.
- Tenaka from Black Butler has one of these in the kitchen!
- Aging in the 2002 arc of Baccano! has a modified mini-gun that she wields one-handed in combination with an over-sized Gurkha Knife in her other hand, much to the shock of her associates. To be fair, they often her compare her to the Terminator.
- The Big O's "O Thunder" is a pair of retractable Gatling arm cannons.
- The Gatling Missile from Voltes V.
- In the Black★Rock Shooter anime, Black★Rock Shooter uses one at several points. At one point, Insane BRS and Mato transformed into BRS duel each other using gatling guns, and it is just as awesome as it sounds.
- Last Exile's Silvana has six hidden rotary cannons behind the forward armor plates. They tend to end battles swiftly.
- In Bleach, BG9's Quincy Cross manifests as a Gatling Gun, though Sui-Feng destroys it before he has a chance to fire it.
- Terminator franchise:
- The Matrix features a helicopter-mounted minigun, which is one of the few weapons that fires too fast for the Agents to dodge.
- Predator features the famous GE M134 minigun "Ol' Painless" wielded by former Navy SEAL, former Pro Wrestler and later Minnesota Governor Jesse Ventura, and was the first handheld minigun ever to be used on film (or in any fiction for that matter). The actors firing that thing had to be braced just offscreen, lest the recoil knock them on their ass. And that was just firing blanks. They also had to connect it to an external power source offscreen, via a wire that went down his pants. Jesse himself has stated that while the gun was suspended from an offscreen crane in early takes, later he actually managed to fire it without. According to him: "You just had to grit your teeth and hold on. It's like firing a chainsaw. It's fucking ridiculous. Why the fuck would anyone want to use something like that?"
- The Sum of All Fears has a scene where a 20mm Vulcan cannon in a Phalanx mounting on the USS John C. Stennis is used in an attempt to defend the ship from a missile attack.
- A criminal uses one in Superman Returns, to no effect.
- The Big Bad's suit in Iron Man has, in addition to a rocket launcher, a huge wrist-mounted Gatling gun.
- In Iron Man 2 the War Machine armor also sports a Gatling gun, which Rhodes uses to great effect against the Hammeroids.
- Unlike in the comics, the movie's Gatling gun defaults over the right shoulder. However, it is mounted on a flexible arm which is then mounted on a sliding rail, enabling it to shoot in any direction, including behind him while flying.
- In the epilogue of Grindhouse's latter film, Planet Terror, Cherry Darling has replaced her rifle-leg with a minigun. There's also a motorbike-mounted chaingun in the Machete trailer. (Apparently the same prop.)
- All robots seem to have rotary guns in the Transformers movie. Including ones made from mobile phones. In the first movie, you also see the famous A-10 firing its GAU-8 Avenger at Scorponok. This was a rare moment of pyrotechnic understatement for Michael Bay. A burst from an Avenger gun is less of a line of pew-pews as seen in the movie, and more like God throwing a fistful of bullets with all his might.
- The 2007 remake of Three Ten To Yuma features a hand-cranked Gatling gun.
- One of the more awesome scenes in Black Hawk Down involved one of the MH-6 Little Bird helicopters obliterating a group of Somali RPG gunners using mounted miniguns.
- In The Last Samurai, the Japanese government purchases a battery of Civil War-era Gatling Guns from the United States. These weapons quickly and efficiently wipe out the remnants of the Samurai during their final Desperation Attack.
- During a car scene in Last Action Hero a door on a van suddenly opens, and a goon steps out with a mounted short-barreled minigun and proceeds to fire it at Arnie's car. Which remains untouched, but the premise of the movie means this actually makes sense.
- The first car chase in Batman Forever: The Batmobile is chased by a pair of '50 Buick Roadmasters, each with two miniguns mounted on the hood. Not that they ever reach real Gatling fire rates, let alone do any halfway realistic damage to anything.
- The Dark Knight. Bruce Wayne conducts a ballistics test using a Gatling Gun with a different kind of bullet in each barrel. There is absolutely no reason to have this other than Rule of Cool and Screw the Rules, I Have Money! which entirely fits Wayne's persona.
- The War Wagon (1967). The Western starring John Wayne and Kirk Douglas, who plan to rob an armored stagecoach (owned by a villainous Cattle Baron) that is armed with a turret-mounted Gatling gun. Since the wagon effectively amounted to a horse-drawn tank the Invulnerable Horses trope had to be in full effect as well.
- The 1983 movie Blue Thunder features a modified Aérospatiale SA-341G Gazelle helicopter with a 20mm Gatling cannon mounted in a turret attached to the nose. This cannon has such a high rate of fire that, during the movie, it is used to saw a police cruiser in half to facilitate the escape of the hero's girlfriend. To provide sufficient drama, the turret gets disabled by a surprise attack to set up the Final Battle.
- Guess what's bolted to the port side of that black truck in Tango & Cash. Right, a 20mm Gatling.

- Jonah uses a small, man-portable Gatling gun at several points during Jonah Hex.
- The SWCC gunners in Act of Valor were not only firing real-life miniguns from their boats during the Gunship Rescue, they were firing live ammunition. That ripping sound they made as they fired was the actual weapon itself being fired with live ammunition.
- Dredd - Ma-Ma proves she really isn't screwing around when she has three massive gatling guns unload on Judge Dredd and his rookie partner. The combined firepower absolutely shreds an entire floor of the complex they're fighting through, along with dozens of bystanders, in one of the messiest scenes of a gorn-packed movie. Dredd and Anderson only survive by blowing a wall open with an explosive round.
- In Sherlock Holmes: A Game of Shadows, the soldiers at Meinhard's weapons factory use Gatling guns with the big Broadwell drums to shoot at Holmes and his crew as they flee.
- The fourth Tremors sequel ends with Hiram gleefully firing off a large gatling gun he's just been given, though it's just for fun as all the Graboids are already dead. In the third film, his descendant Burt uses an anti-aircraft gun mounted on the back of a truck to wipe out a pack of Shriekers.

- "Reason" of Snow Crash ("I told you they'd listen to Reason") is a ridiculously powerful rotary rail gun that fires small fragments of depleted uranium. To drive the point home, at a certain point in the story the main character gets in a fight with two Phalanx CIWS carrier-mounted 20mm Vulcan guns. Reason wins.
- In the novelization of Rambo: First Blood Part II, one of these guns shows up on a helicopter. Every fourth bullet is a tracer bullet, leaving a column of fire from the weapon's mouth, leading to the weapon's nickname of "The Dragon", which is Truth in Television.
- In the Armageddon Trilogy by Robert Rankin, this is lampshaded with a running gag that characters going into a fight say they wish they had 'an amazing rotary machine gun like Blaine had in Predator'. This exact phrase is used consistently until Elvis correctly identifies it as the M134 General Electric mini-gun.
- The Dresden Files. Small Favor. Hendricks, on the helicopter, with the Gatling gun. Which happens to be blasting The Ride of the Valkyries. While being piloted by an actual Valkyrie. Let it never be said that a Chooser of the Slain doesn't know how to make an entrance.
- The Western series Gatling by Jack Slade had as its hero an operative for the Maxim Gun Company named Gatling. The series hook was that the title character used period automatic weapons, including Gatling guns.
- John Ringo's Unto the Breach features the Dragon, a modified Hind helicopter equipped with quad Gatling guns. Another Hind owned by the Kildar uses the more conventional miniguns to port and starboard for defense when used as a troop transport.
- The Hell's Gate series by David Weber gives us the Yerthak Pedestal Gun, a naval weapon designed to destroy torpedo boats and hastily converted by the Fort Salby garrison into makeshift anti-aircraft guns. They are four to six barreled Gatling Cannons that come in one-point-five-inch and two-point-five-inch calibers capable of firing shrapnel rounds, high-explosive or solid ammunition. They're used to shoot down dragons.
- The titular mercenaries in David Drake's Hammers Slammers novels use revolving energy guns called "Tribarrels". Even though they don't fire projectiles the point is the same: three rotating barrels to avoid overheating.
- Mentioned in the Honor Harrington series where variants of the Gatling Gun were used for anti-missile defense until they were quickly replaced by newer Laser Clusters. They are still used by some second- and third-rate powers like the Silesian Confederacy and the Solarian League.
- Subverted in Stone King. The narrator, Saionji, specializes in the use of a mecha-scaled gatling gun, but is rarely able to use it effectively in combat.
Live Action TV
- MythBusters used a Gatling gun as the last stage of the "shooting fish in a barrel" analogy. They busted out a privately owned minigun and unleashed it on the barrel; by the time it was over, the barrel was in a million pieces and there was more lead in the fish than fish.
- They also used the minigun on at least two other occasions: Once, to see if incendiary rounds could blow up a gas tank (busted), see if you could chop down a tree with bullets (confirmed, it even caught on fire) and blow up a propane tank (confirmed).
- The penultimate episode of Stargate Atlantis had a scene of a Wraith being strafed by an A-10. Also, The Daedalus Variations showed us that the Tau'ri ship-mounted railguns are Gatlings.
- Wiseguy. Hitman Roger Loccoco has a car with a Gatling gun firing from the trunk, and twin machine-guns between the headlights.
- G3-X from Kamen Rider Agito has the handheld GX-05 Cerberus, which is utilized as a Finishing Move.
- The Giga Streamer from Tokkei Winspector is a handheld energy Gatling Gun. Recoil and vibration makes it impossible to use effectively without the user wearing a Crash Tector suit — and it has a steep learning curve.
- In one episode of Sons Of Guns, Will is challenged to build an electric Gatling shotgun. The initial attempt fails. Miserably. Changing gears, they take 3 stock semi-auto Saiga shotguns off the shelf and mount them in the reconstructed remains of the Gatling unit. It works well enough that the customer buys the result.
- Andromeda's assault bots are armed with six Gauss Gatling guns, each firing guided rounds.
- Power Rangers: The Red Battlezord has Gatling laser cannons built into its arms. One of the Rescue Megazord's guns is a huge laser Gatling gun (the other was an equally enormous flamethrower). The Delta Megazord has Gatling gun hands. The Supertrain Megazord is armed with a Gatling missile launcher.
- Gabrielle's descendant used one in "The Xena Scrolls.
- Used in an elimination challenge during Season 3 of Top Shot; the goal was to cut through a group of telephone poles.

- A flash-forward in the Babylon 5 episode "Babylon Squared" showed Garibaldi wielding a Gatling-style PPG cannon against unseen attackers.
- Pawn Stars had a segment where they test fired and (and then tried to buy) a 37mm Hotchkiss Revolving cannon. The projectiles alone weighed one pound apiece.
- In the 1989 miniseries adaptation of Brotherhood of the Rose the Jet Ranger used to patrol the sanctuary for retired spies had a gatling mounted on the nose for no apparent reason other than Rule of Cool, as it's not exactly unobtrusive (the helicopter in the book did not have mounted machine guns). Said coolness was ruined anyway by the barrels not spinning when it fired.
- Novic from Priest carries around a Gatling gun. He doesn't seem to have any trouble firing it from the hip.
- The Protomen present Proto Man and Mega Man with Gatling guns for arms in artwork and live performances, as opposed to the plasma cannons they have in the games.

- In the Dino Attack RPG, the character Heavy specializes in this type of weapon. Elite Agent Minerva also used one after her Fire Hammer was downed by her brother Oswald.
- Warhammer 40,000 loves these, from the "assault cannon" on Space Marine Terminators and Dreadnoughts, the Tau's Energy Weapon Burst Cannon, through the tank-shredding Vulcan Mega Bolter and Gatling Blaster, and right up to the Imperator Titan's Hellstorm cannon — a Gatling Energy Weapon the size of a skyscraper.
- BattleTech commonly depicts many machine guns and Auto Cannons as rotary-style guns, and recently introduced the separate Rotary Auto Cannon as its own class of weapon.
- To wit, rotary autocannons can achieve rates of fire up to six times that of "standard" models (and still three times that of an ultra autocannon on double-tap). This comes with an accompanying increase in ammo expenditure and heat buildup and a likewise increasing risk of a temporary jam that needs to be cleared by the MechWarrior or vehicle crew before the weapon can fire again (and renders it explosive until that is done); they also have a shorter effective range than most comparable autocannons of other types. Still, the RAC/5 in particular has practically become the BattleTech universe's iconic incarnation of More Dakka.
- Many mecha and vehicles in Rifts are adopting rotary railguns as antipersonnel weapons.
- Shadowrun has, in addition to its more ordinary miniguns, a vehicle mounted weapon called the "Victory Rotary Assault Cannon", which is Exactly What It Says on the Tin: a rotary gun that fires artillery rounds.
- The evil rat-like Skaven in Warhammer Fantasy Battle, ever on the cutting edge of technological development, have Gatling guns. Naturally, they're called ratling guns.
- GURPS: Ultratech has Gatling versions of everything which are at the low end of the high power weapons but have four times the rate of fire and about twice as many shots.
- Gammarauders, a game about giant mutant cyborg animals fighting in the radioactive wastes after an apocalyptic nuclear war, features the Macrotechnic Popgun, so called because though it is of little use against the bioborgs it can still waste a lot of regular human soldiers, called popcorn because the bioborgs eat them like snacks.
- Warmachine has two warjacks wielding Gatling guns, both part of Cygnar's armies. The first is the Sentinel, a light warjack sporting a Gatling gun for its right arm and a shield on its left and second is its bigger brother, the Cyclone heavy warjack. Cygnar also have chaingun teams among their ground troops.
- Gatling guns exist in New Horizon. They're quite powerful, but extremely expensive.

- Not unsurprisingly, Gatling guns show up in the G.I. Joe lineup, including on such vehicles as the Rattler and the Thunder Machine. One of the original members of the 1982 Joe team, Rock 'n' Roll, traded his M-60 machine gun for a pair of handheld, backpack-fed dual Gatlings when he got a new figure in 1989.
- A gatling gun is seen once in Madness Combat 8: Inundation. The Auditor tries to kill Jesus with it, but misses because Jesus dodges it by levitating towards him very fast. If you think this sounds weird, look at the title again.
- In RWBY, Coco fights by beating her enemies with a purse (which is surprisingly powerful). When this isn't enough, the purse unfolds into a minigun which is several times bigger and can take down several Grimm with ease.
- Richard Gatling invented the Gatling Gun in 1861, in time for occasional use in the American Civil War. It was a hand-cranked device on a small carriage, firing a rifle cartridge. Models varied between ten and six barrels. It may not have been the first machine gun (note that it was hand-cranked - unlike the 1884 Maxim Gun), but by far the most devastating firing rate of its time.
- In 1890, a Gatling was mated with a motor for the first time. This gave such promising results that Gatling himself patented a version with 10 barrels and a built-in electric motor in 1893. It fired 50 rounds per second, a rate that would go unsurpassed for 60 years.
ATF and its predecessor agency, the Internal Revenue Service (IRS), have historically held that the original, crank-operated Gatling Gun, and replicas thereof, are not automatic firearms or machineguns as defined. See Rev. Rul. 55-528, 1955-2 C.B. 482. The original Gatling Gun is a rapid-firing, hand-operated weapon. The rate of fire is regulated by the rapidity of the hand cranking movement, manually controlled by the operator. It is not a "machinegun" as that term is defined in 26 U.S.C. 5845(b) because it is not a weapon that fires automatically.
- When the Vulcan cannon (see below) was being developed, the General Electric engineers borrowed a Gatling gun from a museum and rigged it with an electric motor to test the concept. Possibly an example of research failure, given that Gatling himself had long-since patented such a device, but they still needed to test to see if the rates of fire they wanted were achievable (patenting and testing being two entirely different things.)
- The old museum piece could fire 4000 rounds per minute without problems when equipped with an electric motor instead of a hand crank.
- And the irony behind all this? Gatling was trying to make a weapon so terrible it would scare people off of war.
- Well, end wars quicker at least (in those days, most soldiers died of disease).
- The Gatling was not the only rotary gun produced during the 19th century. Its biggest competitor (in both the literal and figurative senses) was the Hotchkiss Revolving Cannon, which had five barrels and fired a 37mm projectile weighing a full pound at 58 rounds per minute. Rotating barrels were considered 'prior art' dating back to the pepperbox revolver and could not be patented. Gatling's actual patents covered the breach and feed mechanisms.
- The rotary gun experienced renewed popularity in the second half of the 20th century as anti-aircraft weapons. Where firing windows are measured in fractions of seconds, higher rates of fire are a massive advantage and an externally powered gun can't be stopped by a dud cartridge. The 20mm M61 Vulcan, developed in 1959, is still in use to this day on US fighter aircraft. Newer versions of the M61 are lighter and have a faster rate of fire, with derivatives (GAU-22 and GAU-8) firing heavier shells.
- The M134 Minigun is a smaller version of the Vulcan chambered in 7.62 NATO. It's used by some helicopters and ground vehicles as a more rapid-firing alternative to conventional machine guns. The huge ammunition stores required, power feeds and weight of the gun preclude a man-pack configuration. Indeed, the additional weight and space needed to support miniguns can often preclude their use even on said helicopters and ground vehicles if they need the space for carrying more people or cargo. They do see use for such missions as Combat Search And Rescue, where the need for overwhelming firepower combines with relatively light transport needs.
- GE also developed a 5.56 caliber version called the "Six Pack" or "Microgun" (officially the XM214), which was envisaged with the insane fire rate of 9000-10000 rpm. It was tested but not adopted, proving that there were limits to how far one could push the big numbers of little bullets philosophy. The 5.56 lacked enough punch to justify the added weight and complication. It is worth noting though that unlike nearly all the other rotary barrel weapons, this one actually was capable of being man portable, though even then it was generally carried by two men and intended mainly for firing from a vehicle pintle mount or tripod.
- The GAU-8 Avenger, a gun so enormous◊ that the A-10 Thunderbolt II (AKA "Tank-Killer" or "Warthog") was built around it, rather than building the gun into the A-10. It fires seventy 30mm depleted uranium rounds per second, each capable of penetrating 69mm of armor at 500m. The gun can expend its entire magazine of 1,200 rounds in 17 seconds, and at maximum fire rate, the recoil force is a significant fraction of the engines' thrust. Its also so substantial, the gun has to fire from the barrel at the 9 o'clock position, as firing from the traditional 12 o'clock position would push the plane to the side and throw off aim. While not enough to stall the airplane or fly it backward, each burst slows it down enough to help the pilot correct his aim.
- The T249 "Vigilante", a tank with a 37mm Gatling cannon.
- The Russians built the Gryazev-Shipunov GSh-6-23, a gas operated rotary cannon firing at the incredible rate of 10,000 rounds per minute. (Sasha's stated firing rate was a Shout-Out to this gun, although its actual in-game firing rate is 2400.) Its higher-caliber relative the GSh-6-30 fires at 6000 rpm, and an even more powerful CIWS variant can fire 10,000 rounds per minute but is 2 tonnes heavier than the standard 6-30. Gas powered guns trade freedom from an external power source and a vastly lighter structure (The GSh-6-30 weighs only 150 kilograms, less than a third of what the GAU-8 weighs!) for increased vibration at some cost in reliability, and the higher rates of fire required a belt feed system which proved prone to jamming under severe g loads. The beltless feed versions that solved this problem limit the rate of fire to a (still astounding) 8500 RPM. Dud cartridge stoppages are solved through the clever use of ten pyrotechnic "cocking charges" to start/restart the firing cycle.
- There are videos posted all over the internet of the gatling gun toting Chevrolet Suburban created by minigun manufacturer Dillon Aero. Just the thing for third world dictators who don't care about collateral casualties, but rumors that the US Secret Service uses them to protect the president are either Fan Wank propelled by Rule of Cool or something uglier. Either way the manufacturer enjoys free publicity.
- The Neal submachinegun was intended to give the low-power but dirt-cheap 22 Long Rifle round effective military use. Because one round by itself does not do much, the gun was intended to deliver many rounds to the target by the use of five rotating barrels, allowing for a cyclic fire rate of 3000 rounds per minute - though the use of only one firing mechanism makes its relation to the Gatling concept looser than most other rotary guns.
- A wealthy gun nut named Neil Smith managed to increase the amount of dakka of the General Electric M134 Minigun by mounting three of them on one stand. However, there was an accident at a range in 1995 in which a 13-year-old girl was killed. When she shot the monstrous gun—all three Gatlings were operational—, its recoil produced enough inertia to cause it to stand up backwards, tip over and fall upon her.
