The M12B Warthog Force Application Vehicle is a military vehicle employed by the UNSC Armed Forces, and a variant of the venerable M12 Warthog. It was infrequently employed late in the Human-Covenant War and became a predominant sight in the Post-War era.
For more general Warthog design specifics, see the section on the M12 Warthog page here.
The M12B design pattern had been introduced into UNSC service by at least late 2552. It incorporated side compartments into the body, features a more angular body style, utility bars over the hood and around the bed, and several other largely cosmetic changes, while keeping a similar design to the first chassis. This design typically carries several Jerrycans filled with water to be rendered into hydrogen for the engine. It has a lighting system of 24 LED brake light and ULED headlights. This chassis has a programmable nano-prismatic paint to refract color at any chromacity, depending on the vehicle's destination. A security bit was designed to prevent marines from tinkering with the finish, based on early and embarrassing experiences of the tech's deployment. Unlike most models used throughout the Human-Covenant War, this chassis uses a swing-axle system, a redesigned transmission and drive shafts, and constant-velocity joints.
This design does not have an antenna on it, used a military alphabet stencil for the word "UNSC" on its body, has the original UNSC logo on it, and uses white paint for the arrows on the hood of the engine. In the hood, the engine has a black battery, and green chairs. This version of the M12B was stocked by the Marine forces of the UNSC Pillar of Autumn during the Battle of Installation 04 alongside regular M12 Warthogs, and were later used by forces deploying from the UNSC In Amber Clad later in the year during the battles of Mombasa and Delta Halo.
The 2554 M12B Force Application Vehicle "Warthog". What is unique about this variant is that is has a SLED searchlight, has "M-12" written on the steering wheel, used the original black colored UNSC insignia, uses a military alphabet stencil for the word "UNSC" and "STEP" on its body, has a yellow battery in the hood, and has an antenna on it. It also has a side rack holding something. In the seating area this one has brown chairs with bars to reinforce them, and a health pack between the seats of this variant. Unlike other models using this chassis, this one uses a dual spring suspension to keep the vehicle stable in different environments. This model also is darker than other models.
This model of the Warthog uses the post-war UNSC emblem, uses red paint for the arrows on the hood of the engine, and has a slightly darker shade of green. It was employed during the Battle of Requiem and ensuing Requiem Campaign in 2557 and 2558, respectively.
This chassis entered service sometime after the Requiem Campaign. It is equipped with a variety of new weapons across its variants, including the M343A2 chaingun, the M555 Gauss cannon, and the M80 missile launcher, as well as a number of experimental munitions, particularly Warthogs operated by ONI forces.
What makes this model so unique from the previous ones that use the M12B chassis is that is uses an orange colored battery and lacks the overhead screen between the two seats that previous models had. It also has bars to reinforce the chairs.
The 2558 model of M12B Warthog has several variants;
M12B-platform Warthogs typically operate different weaponry to their M12 counterparts. The M12B Warthog LRV generally equips M46 Vulcan or M343A2 chainguns, while the Gauss variant equips M68 Gauss cannons or M555 Gauss cannons and the rocket variant equipping either an M79 rocket launcher or an M80 missile launcher. In addition, several other armed variants of M12B Warthog exist, including one equipped with a mounted flamethrower, and others with increased armour protection.
The M12B has seen extensive alteration for use on the civilian market. The M12S Warthog CST is one of the most prominent examples, outfitted for cross-country and other racing duties. The #550 Scuderia StarSpeed M-12R is another such example, based on the 2558 chassis. Several variants of the "Hog" line of vehicles, including the 2556 and 2558 models are also based on the M12B design. While never actually considered for production, Project HOGSTICKER would also have potentially shared visual similarities with the M12B.
