About this creation
In the Cold War, Germany was in a very precarious situation. The Warsaw pact was just "around the corner". In case of a third world war Germany would have to face the first attacks of the Warsaw pact and the Soviet Union. Military experts reckon a gigantic tank battle in the North German Plain.
Shortly after the development of the successfull Leopard 1, the West German Army prospected a new design to keep pace with newer soviet designs. Because of the cancellation of the MBT-70 project, Germany was searching of an alternative. This ended up in the technically more advanced Leopard 2.
The Leopard 2A6 is the most advanced version in service today. It features the Rheinmetall 120 mm L55 smoothbore gun and a number of other changes, compared to its precedessors. Charateristic is the sloped front armor, which was introduced with the 2A5. The German Army plans to upgrade some Leopards to the 2A7+ version, which was especially developed for asymmertic warfare.
After the German Reunification 1990 there was no longer a need for whole 2125 tanks. Many of them are sold to countries like Spain, Sveden and Canada, which modifies the Leopard to their own needs, resulting in a huge spectrum of variants.
