The M292 is the standard artillery piece of the United States Colonial Marine Corps. Mounted on a 38,000kg armored tracked vehicle is a single 41-calibre 158mm cannon, which fires artillery shells using hypergolic liquid binary propellants. The vehicle carries 78 rounds, which are loaded using automatic systems, and can fire six rounds in ten seconds.
The main round fired by the M292 is the standard Extended Range Full Bore shell, which has an effective range of 39km. A base-bleed addition can extend this range to 48km, while a ramjet-powered shell can hit targets as far away as 62km. Warheads include the standard high-explosive and area-denial mine, as well as the M418 smart shell which homes in on vehicles and structures using a fluidic jet-reaction system to steer.
This variant is identified as the 'A2' because of the air-defense laser turret on the hull roof.
