Specifically, the mismatch in crew values caused by commander's 10% crew skill bonus. Outside of a crew of 1 commander only, 100% crew is a fiction. The client values, given for 100% crew, will normally be taken into battle with 110% crew skill members aside from specific functions, causing their actual performance to deviate from the expected client value. These differences are taken into account in tooltip boxes.

AnnoR90_IS_4M.png

6100000

The IS-4 is a Soviet tier 10 heavy tank.

The project was developed by the Design Bureau of the Chelyabinsk Kirov Plant starting in December 1943. In April 1944 two prototypes of the Object 701 were built. After prototype trials, the design was improved. In late 1944 and early 1945 two more prototypes underwent trials. The Object 701 No. 5 was recommended for adoption into service. However, production was called off in favor of the IS-3 just entering mass-production. After IS-3 production was suspended in 1946, production of the IS-4 began, continuing until 1949. A total of 25 IS-4M tanks were built in 1951. Later all previously produced tanks were modernized to the level of the IS-4M. According to different sources, between 235 and 258 vehicles were built in total; they were stationed in the Far East.

The IS-4 is a very versatile tank, with fair speed, a good gun, and thick sloped armor. When armed with the 122mm M62-T2 gun, it becomes a fearsome opponent, capable of dealing out sustained amounts of damage with its decent damage and good rate of fire. It trades frontal armor from its predecessor, the ST-I, in exchange for better side armor and higher mobility. While it still is not as nimble as its counterpart, the IS-7, it sports better penetration and rate of fire. It also lacks the thin rear armor of the IS-7, and has more armor on the flanks. While its frontal armor is thinner than other tier X tanks, it compensates by having a great slope on the frontal armor plating, meaning that you will bounce enemy shots effectively. Even so, it is best to either hull-down or position yourself at an angle to maximize your sloped armor. Take into consideration that you are a close-range brawler, not a sniper, as your guns have poor accuracy, and if you miss a shot it can be painful. You have the speed and manuverability to get yourself into position quickly and relocate if needed. You can thus utilize cover very effectively - peek out, fire a shot at the enemy, then dive back into saftety. Generally, it is more well-rounded over the IS-7, but it doesn't have any extremely strong points.

The IS-4 marks the end of its Soviet heavy line.

Player Opinion

Pros and Cons

Pros:


  • Relatively agile for its class
  • High penetration and rate of fire
  • Well sloped front armor and small lower glacis
  • High durability
  • Very strong turret armor


Cons:


  • Low turret traverse rate
  • Inaccurate guns
  • Low alpha damage
  • Thinner frontal armor than most tier X heavies


Performance

It is a common tank to see on the battlefield for a very good reason; it has a decent amount of speed, good armor values all around and mounts a high-penetration gun. Many players view the IS-4 as a superior tank to the IS-7 because it does not have the weak rear armor that the IS-7 has. A group of IS-4s can easily tip the tide of battle in their favor if they use the right tactics and stick together. But like some machines of war, it finds itself in a "jack of all trades-master of none" position in that that while performing well, it does not particularly stand out in any one area. However, if played right, the IS-4 can be a feared and respected tank. The IS-4's somewhat weak point is its mobility. Like a T-54, a tracked IS-4 is a dead IS-4. The turret traverse speed is average. It deals decent damage, and combined with its sloped armor, it is a well rounded tank.

Historical Info

Originally developed in competition with the IS-3, the IS-4 was similarly an extensive redesign of the IS-2. The hull was lengthened, with an extra set of road wheels added and an improved engine. Both the hull and turret were uparmoured. Several alternative armaments were explored in paper studies, but ultimately the IS-2's original 122mm gun was retained. An effort was also made to incorporate technical data derived from study of the German wartime Panzer V Panther tank, which influenced the layout of the IS-4's engine cooling system. The tank was approved for mass production in 1948, but due to disappointing speed and mobility, only 200 were manufactured. Most of these were transferred to the Russian Far East in 1950, in preparation for the planned Soviet intervention in the Korean War. When this operation was aborted, the tanks nevertheless remained stationed in the region until their decommissioning in the 1960's.
