The Gatling gun consisted of six to ten barrels revolving around a central shaft. It was fired by turning a hand crank, which rotated the barrels, firing from the bottom barrel while a new round was loaded into the top barrel by means of a hopper or stick magazine on top of the gun. Later, the Model 1881 was designed to use the "Bruce"-style feed system that accepted two rows of .45-70 cartridges. While one row was being fed into the gun, the other could be reloaded to allow for continuous fire. The Gatling gun had a theoretical rate of fire of 1,200 rounds per minute, although 400 rounds per minute was a more realistic estimate in combat.
The Gatling gun was designed in 1861 by American inventor Dr. Richard J. Gatling. Gatling wrote that the purpose of his weapon was to reduce the size of armies and so reduce the number of casualties by showing how futile war is. It saw limited action in the American Civil War, and was later used by European powers to expand their colonial empires by killing warriors of non-industrial cultures. This weapon rarely saw action in the conquest of Native Americans, as the natives know that this weapon was too devistating to face. It is believed that the presence of a Gatling Gun prevented armies from attacking. The weapon would be used by American forces during the Spanish-American War, and would be used by both sides in the Russo-Japanese War.
The Gatling gun remained in service until just before World War I, when more advanced machine guns replaced it on the battlefield; primarily by the Maxim Gun. The Maxim gun (and its variants) were similar in lethality but were more practical as it was more mobile and could fire from prone positions. Gatlings needed horses to carry it long distances and the heavy wheels made it get stuck in mud and difficult to turn.
Decades later, the Gatling gun would serve as a model for the Minigun during the Vietnam War. They functioned almost exactly the same as the Gatling, except the Minigun is powered by a battery or engine and can be mounted on almost any large vehicle; cars, tanks, boats and aircraft.
The Gatling Gun was pitted against the Vickers Machine gun used by Lawrence of Arabia. To test the two long range weapons, they were both situated on a hill and used against 15 static targets and 3 charging targets. The Gatling Gun killed all 3 charging targets and 10 static targets in 1 minute and 11 seconds and the Vickers killed all 3 charging targets and 11 static targets in 1 minute and 41 seconds and jammed once. The edge was given to the Gatling Gun due to it's reliable nature.
- The Gatling gun is one of the only two weapons of season 3 that had it's amount of kills in the simulation revealed. It managed 10,316 kills in the simulation. The other was the Vickers Machine Gun , the weapon it went up against.
- General Custer was allowed to bring Gatling Guns to The Battle of Little Big Horn led by Crazy Horse but refused to take them, believing that they would slow him down and that his army was strong enough to defeat the Lakota without such weapons.
- There is evidence to suggest that Gatling Guns were mounted onto camels .
