M850 Grizzly

"The heavily armored Scorpion tank inflicts massive damage with its primary cannon, but struggles to track fast-moving targets. One of the special Corps upgrades, the Grizzly, adds a double-barreled cannon and a flamethrower that can roast surrounding troops."

Grizzly

The Grizzly is a variant of the M808B Main Battle Tank. It is set to appear in Halo Wars, accessed by upgrading the Scorpion, and usable only by the UNSC "Corps" Faction.

Overview
The Grizzly is a variant of the Scorpion, fielded exclusively by the UNSC Marine Corps. Instead of the standard Scorpion armament (a one-barreled cannon), it is armed with a double-barrelled cannon and a flamethrower.

Triva
It is unknown why it has not yet not been seen or even mentioned between the years of 2525 and 2553. It was possibly too expensive to be further produced, the schematics for it lost (although highly unlikely), it was recalled in favor of the normal Scorpion, or there were too few to be seen frequently.
