M831 Troop Transport

M831 Troop Transport Warthog

The M831 Troop Transport Warthog is a United Nations Space Command ground vehicle.

Halo 2
It was originally named the M831 TT Troop Transport and slated to be a vehicle in Halo 2 along with two other Warthog variants, the Snow Warthog and the Jungle Warthog, but since Bungie faced many time constraints, the only new variant was the M12G1 LAAV "Gauss" Warthog. In Halo 2 its personnel compartment seemed to use a roll cage using roll bars similar to that of modern vehicles.

Halo 3
The M831 TT was sighted in the Halo 3 E3 2007 Trailer, and its presence and naming was confirmed in the leaked scans of the August 2007 issue of the EGM Magazine.

It does not mount a M41 LAAG or M68 Gauss Cannon like most other Warthog models, instead simply having room for three personnel in the rear section along with one driver and a passenger in the front seat. . The Troop Transport relies on its passengers for any defensive or offensive assets. Its roll cage appears to be made of several metal beams unlike normal roll cages.

The Troop Transport Warthog is playable in the Halo 3 campaign levels "Tsavo Highway", "The Storm", and "The Covenant". However, it is unusable in multiplayer.

Trivia

 * It is commonly confused with the Warthog Armored Personnel Carrier, an improvised United Rebel Front vehicle with an armoured cab attached between the front and rear ends of the standard Warthog, giving many extra seats. This has only appeared in Halo: Ghosts of Onyx and in some maps in Halo: Custom Edition.
 * The main reason for adding this new variant into the mix was the start of 4 player co-op that will be introduced in Halo 3
