Another great weapon for the US military and us army. Could prove useful in combating terrorists in Iraq and Syria. The GECAL 50, officially designated by the United States military as the GAU-19/A, is an electrically driven Gatling gun that fires the .50 BMG (12.7×99mm) cartridge.

Prior to the Gatling gun, the only weapons available to militaries capable of firing many projectiles in a short space of time were mass-firing volley weapons like the French Reffye mitrailleuse in 1870–1871, or field cannons firing canister, much like a very large shotgun.

The latter were widely used during and after the Napoleonic Wars. Although the maximum rate of fire was increased by firing multiple projectiles simultaneously, these weapons still needed to be reloaded after each discharge, which for multi-barrel systems like the mitrailleuse was cumbersome and time-consuming.

This negated much of the advantage of their high rate of fire per discharge, making them much less powerful on the battlefield. In comparison, the Gatling gun offered a rapid and continuous rate of fire without having to manually reload by opening the breech.
