M831 Warthog (Earth-5875)

The M831 Troop Transport is a ground vehicle used by the UNSC Marine Corps, based on the design of the M12 Warthog, and manufactured by AMG Transport Dynamics.

Design details
Unlike its sister Warthog designs, the M831 Warthog do not feature its own weapons, although the vehicle makes up for its lack of armament with an extended tray at its rollcage, providing enough space to fit numerous UNSC Marines, in addition to the driver and passenger seats.

Duo to the lack of weapons, the vehicle relies on the capability and firepower provided by the passengers, mostly those in the tray, for both defense and offense. The troop compartment grants the M831 a 360 overlapping field of fire. This is not without its drawbacks, as the Marines will be largely exposed to enemy fire.

Operational history
On July 24, 2552, David-B312 was transported by UNSC Marines in an M831 Warthog to an encampment to meet with and join Noble Team. Only two days later, UNSC Marines from the 3 Echo unit used an M831 Warthog to return to Sword Base, only to be killed by a Type-26 Wraith before they could do so.

On October 20th, 2552, many Marines fought at Battle of Mombasa at Waterfront Highway using M381 Warthogs. Their drivers and passengers died, but the vehicles themselves stood intact until New Mombasa was glassed by the Covenant Fleet of Certain Fulfillment one day later.

Near the end of the Battle of Earth, the UNSC base Crow's Nest was attacked and destroyed by the Covenant.
