M862 Arctic Warthog

The M862 Arctic Warthog (also referred to as the Arctic Hog) is a variant of the M12 Warthog that is outfitted specifically for expeditions in arctic conditions.

Description
Unlike its standard variant, the M862 Warthog features an enclosed cabin and quad-tracks, allowing it to scale icy heights and travel over deep snow.

Trivia

 * The M862 Arctic was planned for inclusion in Halo: Ground Command as part of an upgrade set for the Warthog vehicle which would have included the M862's quad-treads and the M39 rocket turret used by the M12A1 Rocket Warthog.
 * The M862's described characteristics bear an extreme resemblance to a cut vehicle concepted for inclusion in Halo 2. This was later confirmed by Jeff Easterling, with the note that it can change later if 343 Industries needed.
