Gatling Gun
Gatling Po is the world's first machine gun. It was invented by Richard J. Gatling in 1862 during the American Civil War. The characteristic of this gun is that it fires several guns. The barrels are loaded by the action of gravity and the container of guns placed on top of the guns by the action of turning the revolving motion into reciprocating motion. Each barrel is loaded and rotated during half rotation around the central axis and the consumed cartridges are discharged during the second half- do. In modern times, Gatling Poe is using motors instead of manpower. It is mainly used in helicopters, fighter planes, and battlefields, rather than infantry heavy weapons, and is used on the ground as an air defense weapon.
