M12 Chaingun Warthog
From Halopedia, the Halo wiki
The M12 Light Reconnaissance Vehicle (LRV), colloquially referred to as the Chaingun Warthog or simply Warthog, is one of many weaponized configurations of the UNSC's ubiquitous Warthog platform. Models fielded during the Insurrection and the Human-Covenant War featured a turret-mounted M41 Vulcan or M46 Vulcan, while some more modern post-war variants are armed with an M343A2 chaingun.
Removing the turret of a Warthog to create dedicated scout or other weaponized variants of Warthog is a simple process, and has allowed the UNSC to employ many combat configurations of the vehicle with different weapons for different roles. Warthogs equipped with Light Anti-Aircraft chainguns are designated as Warthog Light Reconnaissance Vehicles. The Light Reconnaissance Vehicle is the most common variant of the Warthog seen on the battlefield, designed to eliminate lightly armored personnel and low-flying aircraft.
Chaingun Warthogs have been employed on both the M12 Warthog and M12B Warthog chassis types, all unified with the presence of a 12.7x99mm chaingun of some variety. M12 Warthogs and their derivatives such as the M864 Arctic and Fireball Warthogs typically employed the M41 Vulcan, a triple-barreled, electric-powered, linkless belt-fed machine gun capable of firing 500 penetrating rounds per minute.
M12B variants of LRV, introduced in 2552, serve the same basic function as their forebears, though have upgraded armament to suit their upgraded chassis. M12B Chaingun Warthogs typically employ the M46 Vulcan chaingun, though some introduced by late 2558 employ the M343A2 chaingun. The M12B has seen considerable evolution in the LRV design, with ONI-branded Chaingun Warthogs replacing their typical ammunition with High Explosive Dual Purpose ammunition. UNSC forces working with the Swords of Sanghelios have additionally produced a unique variant of the Chaingun Warthog, designed to incorporate Energy shielding and Subanese crystal ammunition into the vehicle's design.
Theoretically, any Warthog chassis is capable of being fitted with a chaingun mount. The following list summarizes all thus-far observed variants seen in an LRV configuration.
As the most common variant of the M12 Force Application Vehicle, the M12 Chaingun Warthog has been in service with the UNSC for over two centuries. They saw use throughout the Insurrection and into the Human-Covenant War. They would see action in almost every major battle of the war. By 2552, M12B variants of the Chaingun Warthog had entered circulation, though both LRV variants saw action in the battles of Installation 04 and Earth. M12 LRVs would be used by John-117 to escape the destruction of both the downed UNSC Pillar of Autumn and Installation 08.
In the post-war period, the M12 LRV has seen additional use against Covenant remnants, with the vehicle being proliferated among the colonies for use by private corporate entities such as the Liang-Dortmund Corporation for security of their sites against all manner of threat. The 550 Scuderia StarSpeed M-12R would also see use in rally racing on New Carthage while configured as an LRV.

Chaingun Warthogs can be built by all UNSC leaders besides Morgan Kinsano and Avery Johnson at the Garage. Warthogs perform well against infantry and okay against vehicles, aircraft, and structures. They can be upgraded to Gauss Warthogs at Tier 3. In Blitz, Warthogs cost 60 energy while Armored Warthogs cost 80 energy.
