Specifications
Bisons are versatile, light armored vehicles that served as combat elements in a number of roles, including armored personnel carrier and recovery vehicle.

Operational history
Bisons served as combat elements of the old Colonial Military Authority and it remained in service with several UNSC Army units and local militias such as the Sedran Colonial Guard.

Between 2531 and 2537, Serina designed a Bison with a vacuum energy siphon, scientific instrumentation, and cryotech weaponry. As there are no Bisons aboard the, Isabel looked at improving and repurposing the siphon with her own research data on Forerunner vacuum energy cells, but the delicacy and intricacy of Serina's manufacturing template complicates this effort.

It's Coldsnap Launcher fires experimental cryo shells that damage and chill enemies caught in it's area of effect. The Coldsnap Launcher can be upgraded to increase damage, range, and freezing speed. The Bison's Cryo Burst ability allows the Bison to "lock down" and deploy a chilly aura that freezes enemies caught within. They can be purchased at the Armory. Unupgraded Bisons perform well against vehicles, but only okay against infantry, aircraft, and structures. In Blitz the Bison costs 220 energy and is a Legendary Unit.
