class: Tank description: The Leopard (or Leopard 1) is a main battle tank designed and produced by Porsche in West Germany that first entered service in 1965. Developed in an era when HEAT warheads were thought to make conventional heavy armour of limited value, the Leopard focused on firepower in the form of the German-built version of the British L7 105-mm gun, and improved cross-country performance that was unmatched by other designs of the era. The Leopard quickly became a standard of many European militaries, and eventually served as the main battle tank in over a dozen countries worldwide, with West Germany, Italy and the Netherlands being the largest operators until their retirement. Currently, the largest operators are Greece, with 520 vehicles, Turkey, with 397 vehicles and Brazil with 378 vehicles. introduced: 1974 manufacturer: Krauss-Maffei origin: Germany price: 18 role: Main Battle Tank variants: Leopard 1A3: {}
