Trivia

 * The Grizzly is similar to the Mammoth Tank from the Command and Conquer series, having 4 treads and dual barrels, and a secondary weapon. In addition, the Grizzly is notable for its size to emphasize its dominance over other units much like the Mammoth Tank.
 * The Grizzly Tank may also be named after the tank of the same name from Command and Conquer: Red Alert 2.
