The Alvis Scorpion (Combat Vehicle Reconnaissance (Tracked)) is a British light tank that first appeared in 1969 to replace the Saladin armoured car, and entered service in 1972. The Alvis Scorpion is manned by a crew of three protected by 12.7 mm thick armour, and armed with a 76 mm gun and a coaxial 7.62 mm machine-gun. A Jaguar 4.2 litrepetrol engine provides a top speed of 80 kmh and a range of 644 km. The Alvis Scorpion can be fitted with flotation screens to add amphibious capabilities, and these proved effective during the landings of the Falklands War of 1982. Research Alvis Scorpion
