The standard Warthog offers two seats (driver, side passenger) and a cargo bed for carrying equipment or other personnel. Variants of the Warthog have been in service with UNSC forces for over two centuries.
M12: The most common series within the FAV platform is the M12 Light Reconnaissance Vehicle (LRV) fitted with a pneumatically powered, 360-degree rotation multi-purpose light anti-aircraft machine gun. Major variants are informally denoted by their year of production.
M12A1: The M12A1 Light Anti-armor Vehicle (LAAV) "Rocket Hog" saw limited use, but packed an impressive amount of firepower onto a mobile platform in the form of a heavy M39 Rocket Turret.
M12G: The primary anti-armor variant of the FAV platform is easily the M12G LAAV, which leverages the devastatingly effective Gauss Cannon.
M12R: Equipped with an M79 Multiple Launch Rocket System (MLRS), the M12R "Missile Hog" proved invaluable in operations such as the Szurdok Ridge offensive on Reach in 2552.
M831: The standard non-combat Warthog used for personnel transport. Instead of armament, the M831 "Troop Hog" features a protective roll-cage and seating for up to four passengers in side-facing bench seats. A high-powered spotlight is also fitted. While the passengers can generate an impressive amount of firepower (if properly equipped), they are also exposed to enemy attack and vulnerable to rollovers and other catastrophes. The four subvariants: M831A, M831B, M831C, and M831D differ in minor ways.
M862: Referred to as the "Arctic Hog", this extreme-environment variant features an enclosed cabin and quad-tracks, allowing it to scale icy heights and travel over deep snow.
M864: Though modified for cold-weather operations, the M864 does not have the extreme mobility modifications of the M862.
M868: Hostile-environment variant for operations in a tropical environment. Most notable changes are a further ruggedized suspension and double application of anti-corrosion coatings.
M914: Utilitarian by nature, the M914 Recovery Transport is a rare variant designed for extraction of Warthogs that have become immobilized, and for use as a mobile repair bay.
The Hog: Civilian variant of the M12.
