M864 Arctic Warthog
From Halopedia, the Halo wiki
The M864 Arctic Warthog is a variant of the M12 Warthog that is camouflaged and outfitted specifically for expeditions in arctic conditions. Despite these modifications, it does not have the extreme mobility modifications of the M862 variant.
The M864 Arctic Warthog, one of several Warthogs designed for cold weather fielding. Unlike the M862 Arctic Warthog, the M864 does not feature extensive mobility modifications such as tracks instead of wheels, and enclosed doors for crew comfort. In this regard, it bears more regard for the M12B Warthog's Tundra variant, as it has no external physical change from its base variant aside from a snow camouflage paint job.
The M864 appears exclusively on the Halo 3 multiplayer map Avalanche, replacing the standard M12 Warthog available usually in the game. This Warthog, like all other UNSC vehicles on the map, is outfitted with a special snow camouflage more suitable for the map's winter conditions. Despite this, however, it does not have any difference to the regular Warthog available in the game regarding gameplay mechanics.
