The M850 Main Battle Tank, commonly known as the Grizzly, is a heavily armored UNSC tank. It is similar to its older brother the M808B Main Battle Tank but much larger and far more powerful.

Overview & Background



The Grizzly is protected by thick armor plating which allows it to survive even the fiercest attacks and features dual M310 120mm Smooth-Bore High-Velocity Cannons mounted in its turret. These cannons can easily punch a hole through almost any Covenant vehicle and fire S1 canister shells to decimate infantry formations. Twin co-axially mounted M247T Medium Machine Guns gives it additional firepower.

Operation Service

The Grizzly first entered service in 2509. Grizzlies were used to great effect during the Liberation of Harvest, and the UNSC Spirit of Fire contained a robust inventory of M850s during the extraordinary events of 2531. During the Battle of Installation 04, two of the four Grizzly tanks from the Pillar of Autumn were used during the Assault on The Control Room.

Gameplay Information
