M12G1 Gauss Warthog

Gauss Warthog The M12G1 Light Anti-Armor Vehicle (abbreviated M12G1 LAAV), more commonly known as the Gauss Warthog, or Gauss Hog, is a UNSC ground vehicle. It is a variant of the Warthog series of vehicle, but is much less common than the ubiquitous M12 Warthog LRV.

Overview
The M12G1 Warthog is primarily used as a light anti-armor vehicle, designed to quickly and efficiently defeat light to medium armored vehicles such as the Brute Chopper and Ghost. It is almost exactly the same in every detail to the standard M12 Warthog LRV, except that the LAAG on the back has been replaced with a M68 Gauss Cannon which fires 25mm hypersonic speed projectiles by asynchronous magnetic acceleration in the base of the cannon. It takes about a half a second to recharge between shots.

Multiplayer Strategy

 * The Gauss Warthog is very effective against light to medium vehicles, armor, and even infantry, but tends to be ineffective against tanks, as it takes multiple direct hits to kill the driver and even more hits to destroy the tank itself. In general, it is advisable to circle the tank to be destroyed, driving erratically but smoothly, so as to both avoid fire from the tank and hit it more accurately in the cockpit and driver's seat. Beware of the tank's anti-infantry gunner, who will likely be more able to target the fast-moving Gauss Warthog than the pilot.
 * Be especially careful of Ghosts, as they can strafe quickly enough to avoid the Gauss cannon and do fatal damage in just seconds. Despite it being a light anti-armor vehicle meant for taking out Ghosts, Brute Choppers, even Banshees, it is extremely effective against infantry due to its sheer power.
 * Even though it doesn't have a zoom feature, the reticule is accurate enough that you can pick off infantry with it at medium to long range, with satisfying effect.

Halo Wars
The Gauss Warthog appears in Halo Wars as the final upgrade to the standard Warthog, replacing its previous M41 LAAG at a cost of 800 resource units and a minimum technological requirement of three power units. The result is a dramatic increase in combat capability versus vehicles and also to a slightly lesser extent, infantry.

Trivia

 * The projectile beam from the Gauss Warthog in Halo 2 is green; however, in Halo 3, the beam is blue.
 * During the Halo 2 demo trailer, the Gauss was shooting at a fairly decent speed. In an early beta multiplayer phase, however, the Gauss seemed to be slowed down and also seemed to have lost all of its hype. It was later revamped to its original rate of fire during the game's final stages.
 * In the E3 2000 Halo: Combat Evolved trailer, a Warthog had a turret similar to the Halo 2 Gauss turret, due to the fact it was originally part of Halo: Combat Evolved. However, just like many other things, it was cut and dropped, but then reappeared in Halo 2.
 * Ferrex said in a thread, "While the Warthog Gauss rifle is modeled as a magnetic acceleration cannon, the sound and effects are actually those of a railgun, which operates on a different principle. However, the sound and effects were so cool that we couldn't not use them."
