The most massive modification of the German Leopard 2 main battle tank. Unlike previous modifications, the 2A4 received a new turret with reinforced armor protection and a digital fire control system. In terms of its combat characteristics, the tank is one of the most versatile MBTs in its class due to its superior dynamics and speed, as well as the powerful Rh 120 L/44 120 mm gun with fast reloading.
