Leopard (later known as Leopard 1) tank first entered service in 1965. The Leopard used a German-built version of the British 105 mm L7 gun, and had improved cross-country performance that was unmatched by other designs of the era. The Leopard quickly became a standard of European forces, and eventually served as the main battle tank in over a dozen countries worldwide, but the German Leopards never saw combat. In the German Army, the Leopard 1 MBTs have been phased out in 2003 while Leopard 1-derived vehicles are still widely used. The Leopard 2 MBTs have taken over the MBT role and first entering service in 1979. The Leopard 2 have served in the armed forces of Germany and twelve other European countries, as well as several non-European nations. More than 3,480 Leopard 2s have been manufactured. The Leopard 2 first saw combat in Kosovo with the German Army and has also seen action in Afghanistan with the Danish and Canadian ISAF forces. KFOR The German contingent of the Kosovo Force operated a number of Leopard 2A4s and 2A5s in Kosovo during the NATO-led international peacekeeping force responsible for establishing a secure environment. Also Canadian Leopard C1A1s, served with Lord Strathcona's Horse (Royal Canadians) in the 1999 KFOR mission in Kosovo. Denmark also sent some Leopard 1 tanks, which fought in Operation Bøllebank and Operation Amanda, which are believed to be the first combat engagements of the Leopard 1 tank.
