"Usually the Good Lord works In mysterious ways. But not today! This here is 66 tons of straight-up, HE-spewin' dee-vine intervention! If God is love, then you can call me cupid!"
— Sergeant Major Avery Junior Johnson, Halo 2

“The M808 Main Battle Tank,commonly known as the Scorpion, is the United Nations Space Command's premier armored mobile weapons platform. The tank was originally manufactured by Chalybs Defense Solutions, until Acheron Security took claim following the Human-Covenant War and the destruction of numerous CDS facilities on Meridian
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. Additionally, the Scorpion's functional uses are numerous and widely varied—although the UNSC predominantly uses the tank for direct engagements, local defense, and anti-armor operations. 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.
The M808 has proven itself to be the workhorse of UNSC armored attack vehicles. The tank's 90mm cannon can deliver a devastating blow to all targets—infantry or armor. The M808's thick ceramic-titanium armor can withstand a direct hit from a Covenant fuel rod cannon and survive with enough armor to keep fighting. The Scorpion's two-man crew severely limits human casualties; along with its main offensive capabilities, one other man can man the tank's turret as a gunner, and four infantrymen can sit on the tread pods of the tank, providing supporting fire while using the tank as a transport.”
