The name comes from the term "gatling gun": the cannons are armed with a pair of these lethal weapons. Firing a high-caliber slug with a tremendous muzzle velocity, the cannons can target both ground vehicles and aircraft. Deployed at various Yuri bases worldwide, these structures are staples of Yuri's defensive networks. Notably, they made up the defense of the Psychic Dominator on Alcatraz Island when the Allies attempted a last-ditch effort to prevent the superweapon from being activated.
