Description
: The **IS-3** is a Heavy Tank developed by the Soviet Union in the closing phase of the Second World War, entering production in 1945 with its distinctive "pike nose" glacis and hemispherical turret; it shocked Western observers when paraded in Berlin and became a benchmark for postwar heavy tank design. It is a tracked vehicle weighing 48 tonnes with a crew of four — driver, gunner, commander, and loader. The **V-2IS** diesel delivers 520 horsepower, giving 10.8 hp/t and a maximum speed of 40 km/h.
Main armament is the **122mm D-25T** gun, supported by a coaxial **7.62mm DT-28** and a commander's **12.7mm DSHK** on a stabilized cupola. The gunner uses a 4x telescope sight with no rangefinder.
