The M808 Main Battle Tank, commonly known as the Scorpion, is the United Nations Space Command's mainline armored mobile weapons platform. The Scorpion has remained in service for centuries due to its combination of affordability, simplicity, and versatility and its rugged, adaptable design, features that cannot be matched by any "superior" main battle tank design. A result of the tank's effectiveness and practicality, the M808 Scorpion has become the UNSC's template for all modern main battle tank designs.
