A Gatling gun is an early type of machine gun with multiple barrels rotating around a central axis. It was invented by Richard Gatling in the 1860s and was one of the first successful rapid-fire weapons. The Gatling gun operated by a hand crank that rotated the barrels and loaded, fired, and ejected cartridges. It was used in various conflicts during the late 19th century. Think of it as the granddaddy of modern machine guns. Gatling guns are like the rapid-fire ancestors of today's weapons.
