Utility light attack vehicle.
The most versatile vehicle in the UNSC inventory, the Warthog is armed with a light machine gun which can handle all but the most heavily armored vehicles. In a pinch the vehicle can be used to ram a target, directing the driver to careen into [and ideally over] enemy infantry. The autocannon can be upgraded to a gauss cannon, which substantially increases the Warthog's anti-armor capabilities.
The M12 Light Reconnaissance Vehicle, more commonly known as the Warthog, is a quintessentially tough and durable UNSC vehicle, manufactured in one variant or another for centuries. The towing winch system at the front of the vehicle resembles a warthog’s tusks, giving it its name, and it has enhanced suspension and four-wheel steering for a smooth ride over any battlefield. Highly configurable and adaptable, dozens of specialized Warthog loadouts are loaded into the Spirit of Fire's datastores, awaiting use.
