The Minigun is a type of gatling gun and can be seen on pedestal mounts during the course of the film Dredd. The concept designer involved confirms that they were "loosely based on the GECAL and were using .50 BMG shell casings [...] except we made ours six-barreled.
Ma-Ma used three mounted Miniguns to slaughter dozens of Peach Trees residents in a futile attempt to kill Judge Dredd. There is a track on the soundtrack called "Mini-Guns" that plays during this sequence.
It features Gatling-style rotating air-cooled barrels with an external power source, normally an electric motor. The "Mini" in the name is in comparison to designs that use a similar firing mechanism but larger shells, such as General Electric's earlier 20-millimeter M61 Vulcan, and "gun" for a caliber size smaller than that of a cannon, typically 20 mm and higher.
The Minigun is used by several branches of the U.S. military. Versions are designated M134 and XM196 by the United States Army, and GAU-2/A and GAU-17/A by the U.S. Air Force and U.S. Navy.
"Minigun" refers to a specific model of weapon that General Electric originally produced, but the term "minigun" has popularly come to refer to any externally powered Gatling gun of rifle caliber. The term is also used to refer to guns of similar rates of fire and configuration regardless of power source and caliber.
