significant machining in its construction). Casting also made it easier to vary the shape and thickness of the armour, which also reduced the exterior surface relative to tank volume. However, casting had to account for the metal shrinking as it cooled (becoming denser) and with limitations on Soviet casting technology, IS-2 armour thickness could vary even when produced from the same mold. Lower-quality alloys had to sometimes be used, substituting manganese for nickel, meaning that while the armour had high hardness and resisted penetration better than steel, it was also quite brittle and thus at risk of shattering.

The special tank regiments were reserved for important attacks, often to spearhead attempts to break through fortified German positions like anti-tank defence lines and bunkers. The tanks supported infantry in the assault by destroying bunkers, buildings, dug-in weapons and engaging German armoured vehicles. Once a breakthrough was achieved, lighter and more mobile tanks were used for exploitation and mopping-up. The IS-2 tank first saw action in

The KV's armor was less well-shaped and featured heavy armor even on the rear, while the IS series concentrated its armor at the front. The IS-2 was slightly heavier than the

September to October 1943, a total of 130 KV-85s were produced, before the assembly lines began to shift over. Like the KV-1S, the KV-85 served in dwindling numbers and was quickly overshadowed by the superior IS series.

Another limitation imposed by the size of its ammunition in a relatively small vehicle was the ammunition stowage: only 28 rounds could be carried inside the tank, with a complement of 20 HE rounds, and 8 AP rounds the norm.

In the mid-1950s, the remaining IS-2 tanks (mostly model 1944 variants although several model 1943 variants) were upgraded to the IS-2M standard, which introduced fittings such as external fuel tanks on the rear hull (the basic IS-2 had these only on the hull sides), stowage bins on both sides of the

By 1943, engineers had succeeded in mounting the 85 mm gun to the T-34 medium tank, making it as well-armed as the KV-85 heavy tank. Efforts to up-gun the IS-85 began in late 1943. Two candidate weapons were the D-25 122 mm tank gun, the ballistic characteristics of which were identical to

The IS-122 prototype replaced the IS-85 and began mass production as the IS-2. The 85 mm guns could be reserved for the new T-34-85 medium tank and some of the IS-1s built were rearmed before leaving the factory and issued as IS-2s. It was slightly lighter and faster than the heaviest KV model

After testing both the D-25 and D-10 on the IS-122, the former was selected as the main armament of the new tank. The D-25 used a separate shell and powder charge, resulting in a lower rate of fire compared to the single-piece ammunition used in most tanks, a serious disadvantage in tank-to-tank

In comparison to the Tiger I, the IS-2 had advantages in armour, even though it was 10 tons lighter. In 1944, the IS-2 was the only large-scale Allied tank whose armor provided some protection from the well-known Tiger 88mm long-barreled guns and
