M810B Grizzly Main Battle Tank

"It looks more old-school than the Scorpion, but those treads have some kinda trick that lets 'em climb just as well."

- UNSC Marine

The M810B Grizzly was a main battle tank of the UNSC Marine Corps during the Saulosian campaign.

Design
The M810B was designed as a replacement to the venerable M808G Scorpion. The following changes were made:


 * 90mm cannon upgraded to 105mm.
 * Coaxial 12.7mm machine gun mounted alongside the cannon.
 * Four-track system replaced with traditional two-track

In the last change, the Grizzly was able to retain the mobility of its predecessor because of a new semi-rigid plastic-and-metal frame that held the tracks in place, yet could still bend well enough to allow travel over all but the most broken ground.
