Mongoose (fiction)

Summary
This vehicle did not make it into the final version of Halo 2, but is showed in the "behind-the-scenes" video on the Limited Edition version of Halo 2.

The Marines' fastest vehicle is the Mongoose All-Terrain Vehicle. Essentially four wheels and an engine, this ATV can travel very fast over nearly all types of terrain. With no weapons on board, the driver must use his own weapons for defense, though this means taking one hand away from the vehicle's already precarious controls. It serves a similar purpose of the Covenant Ghost.
