Warthog

The M12 Force Application Vehicle, more commonly known as the Warthog or simply the Hog, is a United Nations Space Command ground vehicle

Overview
The M12 FAV Warthog is the UNSC's primary ground vehicle, used for its scouting and reconnaissance capacity, or as an integral part of a mechanized infantry unit; the M12 has been a part of the UNSC's armored vehicle fleet for fifty years, and is the most recognizable vehicle in their arsenal. It is a highly mobile, all-wheel-drive, all-wheel-steering, ICE-powered vehicle equipped with a manual transmission. The M12 is a four-wheel all-terrain vehicle capable of going over any obstacle without difficulty; under the hood the M12's power is generated by a forward-housed low-profile liquid-cooled hydrogen-injected ICE I/C plant, coupled with an automatic infinitely variable transmission (IVT). The hydrogen fuel is burned at very high temperature with a synthetic carbon/silicon catalyst to achieve even better fuel consumption. This hydrogen engine is the standard among all UNSC ground based vehicles, replacing fossil fuel-based engines some 400 years ago. The M12 features a Graf/Hauptman solar/saline actuator, and will convert up to twelve liters of fresh, brackish or salt water into hydrogen on the fly, detritus is compacted on board, this allows the Warthog to travel 790 kilometers or 490 miles before it needs to be refueled. The M12 is a huge, unwieldy, difficult to steer vehicle – until a user learns how to drive it properly. With proper application of the hand, or "e-brake" the M12 can actually turn on a dime. Massive disc brakes and its automatic braking systems allow the vehicle to come to a near immediate, but controlled stop should the driver be ejected, or choose to leave the vehicle. The Warthog's tires have moved away from previous inert-gas pocket inflation with equally burst-proof single unit nanotube skeletons. They provide the buoyancy and ride of gas-pocket tires, but are almost indestructible. The relatively massive tires are a joint project between Michelin-Vance and AMG.

The M12's design places it into the jeep family of vehicles; it has no doors and has a total seating of two or three. The M12's description as a reconnaissance vehicle is, at best, an understatement; the M12 has both offensive and defensive capabilities. The M12 can be configured to become a troop carrier, armament carrier, ambulance, reconnaissance vehicle, or communications vehicle. All M12-based vehicles are designed to travel both on and off-road, in all weather conditions.
