M12G1 Gauss Warthog

The M12G1 Light Anti-Armor Vehicle (M12G1 LAAV), commonly known as the Gauss Warthog, is a United Nations Space Command ground vehicle. The M12G1 is a variant of the M12 Warthog FAV armed with a mounted Gauss cannon, with the M68 serving as standard during the Human-Covenant War and the M70 coming into use in the following years.

Design details
The M12G1 LAAV is one of the UNSC's anti-armor vehicles. It is primarily designed to quickly and efficiently defeat lightly armored vehicles such as the Type-25 Chopper and, but can also be a threat to s. The Gauss Warthog is almost exactly the same in every detail to the M12 Chaingun Warthog except that it is equipped with a mounted M68 Gauss Cannon, which fires a 25mm hypersonic projectile by means of magnetic acceleration. It takes about a half a second to recharge between cannon shots. Although it appears more rarely than the standard Warthog, its capabilities make it a fearsome, agile and powerful vehicle to use.

Usage
Gauss Warthogs are typically employed by the UNSC Army and UNSC Marine Corps, serving primarily in an anti-tank/ anti-armor role during the Human-Covenant War. During the conflict, Gauss-equipped Warthogs were able to use rugged terrain to its advantage to pick off Covenant vehicles, whose propulsion drives were slowed by foliage. However, Gauss vehicles assigned to more remote outposts would additionally be expected to serve in an anti-aircraft role, and the driver and gunner team would drill for both tasks. Specialised Gauss Warthogs are also employed by the Office of Naval Intelligence, who developed and tested prototype Gauss technology during the Requiem Campaign.

Outside of the UNSC, some corporate entities such as the Liang-Dortmund Corporation have been permitted to purchase Gauss Warthogs - among other milspec equipment - for defense against dangerous megafauna on alien worlds. However, these vehicles often end up deployed for riot suppression against crowds.

Operational history
Numerous Gauss Warthogs were used by the UNSC during the Harvest Campaign. Sergeant John Forge used a Gauss Warthog during the battles of Arcadia and the Etran Harborage.

In the opening actions of the Fall of Reach in July 2552, Noble Team members Catherine-B320 and SPARTAN-B312 drove a Gauss Warthog when returning to Sword Base after clearing out Covenant hostiles in Sword Base's outposts Airview Base and Farragut Station. They used the Warthog to destroy a number of Revenants and other troops guarding the gate of the base.

During the Battle of Mombasa, Gunnery Sergeant Stacker drove a Gauss Warthog and offered it to MCPO John-117 in Kilindini Park Cultural Center, New Mombasa. John-117 used Stacker's Warthog to fight his way through Covenant heavy armor and reach a UNSC Marine command post in Sector B. As the Battle of Mombasa drew to a close, ODSTs Edward Buck and the Rookie commandeered a Gauss Warthog on the city's Waterfront Highway in order to cover Captain Veronica Dare's commandeered Olifant that the intelligence officer was using to escort an important asset out of the city.

During the Battle of Installation 05, UNSC Marine forces assaulting the Installation 05 Library deployed a Gauss Warthog along with many other vehicles to battle the Flood forms in the Quarantine Zone. They were either killed or infected by the Flood, as the Warthog was under the control of several combat forms by the time Arbiter Thel 'Vadamee and his Special Operations team passed through the area. The Warthog, along with many other Flood-controlled vehicles were destroyed by the Covenant team as they made their way towards the Library.

During the final battle of the Human-Covenant War, the Marines from the Forward Unto Dawn utilized a Gauss Warthog during their push to secure Installation 00's Cartographer. The Gauss Warthog was offered to John-117 by PFC Chips Dubbo. The Spartan and Dubbo used the Warthog to aid a trio of Scorpion tanks in destroying a large contingent of Wraiths and other Covenant units guarding the Cartographer building. The Warthog also helped John-117 destroy a Scarab that entered the battle shortly afterwards. Another Gauss Warthog was dropped by a Pelican to support the UNSC forces attacking the Citadel. Many more aided the Master Chief during his battle against a pair of Scarabs that were dropped in from orbit in front of the Citadel by the Covenant.

In July 2557, during the initial battle on Requiem, several Gauss Warthogs were deployed to engage Covenant ground forces. Several were attached to Gypsy Company, and John-117 used one during his defense of the Mammoth assigned to destroy the Forerunner particle cannons guarding the gravity well holding the within the planet. Upon the Infinity ' s return to Requiem later in 2558, more Gauss Hogs were deployed to the interior of Requiem to aid in the removal of Covenant forces. Several were used by Fireteam Crimson during their missions, including the clearing of the location known as Quarry and the defense of Cauldron Base. During the campaign, several prototype Gauss Warthogs sporting new and classified weaponry were deployed by ONI in classified operations for the purpose of field-testing.

On October 25, 2558, during the Battle of Meridian, Fireteam Osiris used a Corp Gauss Warthog to combat Promethean forces while attempting to return to their D79-TC Pelican.

Trivia

 * In the E3 2000 Halo: Combat Evolved trailer, a Warthog was shown featuring a turret similar in appearance to the Halo 2 Gauss turret.
 * In the Halo Wars campaign, Sergeant Forge's Warthog will always be an M12G1, regardless of whether the player has researched the Gauss cannon.
 * During the Halo 2 E3 Demo, the Gauss cannon of the Gauss Warthog was shooting at a fairly rapid speed. In an early beta multiplayer phase, however, the Gauss cannon had been slowed down considerably. It was later revamped to its original rate of fire during the game's final stages.
 * In Halo: Reach, the Gauss cannon is capable of shooting through all Forged objects in the multiplayer map Forge World.
