Cut Halo 3 vehicles

During the production of Halo 3, several vehicles were concepted and implemented - though ultimately cut for various reasons.

Corporate starships
Several corporate starships were concepted by Isaac Hannaford for Halo 3. He described them as used by a corporation, and said the ships were a mix of military and civilian themes. They are equipped with limited weapons and transport mercenaries and scientists.

Medical Troop Warthog
A Medical Troop Warthog was a variant of the M831 Troop Transport 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. Interestingly, Marines will sit on the stretchers like they would do on a normal M831 Troop Transport Warthog, suggesting that it was never fully completed.

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.
