M831 Troop Transport

Troop Transport Warthog

The Troop Transport Warthog is 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 the only new variant was the M12G1 LAAV "Gauss" Warthog.

Halo 3
The concept of 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.

Trivia

 * It is commonly confused with the Warthog Armored Personnel Carrier, a 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.
