IS-1 Komroti is a Soviet Tank unit in Steel Division II.
Background[ | ]
An evolution of the Kliment Voroshilov tank, the Iosif Stalin series of tanks was born at the SKB-2 design bureau at the Chelyabinsk Kirov Plant. The capture of a Tiger tank in early 1943 showed the need for a tank capable of fighting Germany's big cat on even footing. The SKB-2 bureau devised the KV-85, a KV-1 with an 85mm tank gun, to bolster the firepower of Soviet tank units in the summer of 1943 while they worked on a new design.
The first generation IS tank, IS-85 was born out of a cancelled KV-13 prototype, featuring a superior armor layout, better reliability, and a large, three-man turret accommodating the 85mm gun. Pressed into service in October 1943, production lasted until January 1944. By then, the T-34 armed with the same gun was commonplace, and Soviet engineers focused on upgunning the existing tank. The new IS-122 entered service in January 1944, armed with a 122mm gun that could destroy any German tank from well outside their firing range.
The end result was a tank lighter than the Tiger and almost equal to the Panther, at 46 tons, with thicker armor than either of the big cats, and a decisive advantage in firepower. It was also a potent tool for breakthroughs, as its 122mm gun was incredibly effective against fortifications and soft targets. A total of 3 854 IS tanks were manufactured before production terminated in 1945.
IS-1, initially designated IS-85, was the first generation Iosif Stalin tank. It was armed with the 85mm tank gun and was quickly matched in terms of firepower by T-34 tanks. With the introduction of the IS-122, IS-1s still on the factory floors were quickly upgraded with 122mm guns.
