The COGSSMG23, usually referred to as the "Spitfire" by Gears, is a sub-machine gun that first came into widespread use during the Human-Locust Wars. A robust firearm, the Spitfire serves as an effective anti-personnel sidearm and a welcome improvement over the Snub pistol that Gears currently use. Although the weapon is comparatively young, the COG military expect the weapon to become the standard sidearm of the Gears within the next year, although now many are doubtful that the COG will even last that long in the face of repeated Locust attacks.
