The Leopard 2 is synonymous with leading tank technology worldwide. Its versatile superiority is used by the armed forces of 16 nations. Its outstanding combat capability is due to an optimum combination of fire power, protection and mobility. In the current German Army version (A6M) the fire power has been increased by the new 120 mm smooth bore cannon L/55. The primary and secondary protection of the system is still effective against modern types of ammunition due to continuous further developments. The "M" stands for extended mine protection, including with an additional base plate.
