M874 Buffalo Heavy Support Vehicle

The, or Buffalo, is a vehicle used by the UNSC.

Description
The Buffalo is a large vehicle, built from an 18-wheeler's diesel cab. While one can sit in and fire from the passenger seat, some even having been jury-rigged with a small, two-passenger "nest" on top of the flat cab roof, the true strength of the Buffalo is the large, armored ammo/equipment storage compartment (15ft long by 6ft wide) behind the cab. In addition, the massive towing power of the Buffalo allows for the towing of two to four mobile equipment pieces, such as the Shortbow, from its' two rear hitches, two more capable of being pulled via special attachment hitches, always carried by in Buffalo's, that were designed to attach equipment pieces to other equipment pieces.

M913 Bison Armored Personal Carrier
A variation of the Buffalo, the Bison remains the same in all aspects but the rear compartment, which is re-purposed as a personal chamber, complete with firing slots in the sides and a large exit ramp in the rear, guarded by two machine guns.
