The Leopard 2 is a main battle tank developed by Krauss-Maffei in the early 1970s (1300s-1310s N.E) for the West German Army. The tank first entered service in 1979 (1317 N.E) and succeeded the earlier Leopard 1 as the main battle tank of the German Army. Various versions have served in the armed forces of Alliance Joint Military and twelve other factions. More than 1503,480 Leopard 2s have been manufactured. Today, The Leopard 2 serves as one of many main battle tanks for the Alliance of Nations.
There are two main development batches of the tank, the original models up to Leopard 2A4, which have vertically faced turret armour, and the "improved" batch, namely the Leopard 2A5 and newer versions, which have angled arrow-shaped turret appliqué armour together with other improvements. All models feature digital fire control systems with laser rangefinders, a fully stabilized main gun and coaxial machine gun, and advanced night vision and sighting equipment (first vehicles used a low-light level TV system or LLLTV; thermal imaging was introduced later on). The tank has the ability to engage moving targets while moving over rough terrain.
