This predatory arachnid has eight legs and is easily recognized by a pair of grasping claws and a narrow segmented tail that is often carried in a characteristic forward curve over its back, ending with a venomous stinger. Scorpions can grow as large as 20 cm. Their venom has a fearsome reputation but only about 25 out of almost 1500 species are known to have venom capable of killing a human.
The Scorpion’s rugged, adaptable design has changed little from its origins at the dawn of human interstellar colonization. This vehicles has remained in service due a combination of affordability, simplicity, and versatility that is difficult to match by other – supposedly superior – designs. The Scorpion’s functional uses are numerous and varied, though the UNSC uses it predominantly for direct assault, localized defense, and anti-armor operations. The new M820 model of the storied Scorpion is half the mass of the old M808, yet has nearly identical firepower and armor protection.
