The Medical Troop Warthog was a variant of the M831 Warthog that was to appear in Halo 3. It was cut from the game during development; however, its files remained in the game's code and can be accessed through modding. It was first discovered in the files of the Halo 3 Beta and is present in the final game as well, although it was never used.
- The Medical Troop Hog appears to be the same as a standard M831 but with the addition of two stretchers placed over the seats in the troop bed.
- Presumably, this vehicle's role would have been to transport wounded troops off of the battlefield to an aid station. It was therefore likely intended to be used during cinematics rather than during gameplay.
