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.

IS-2M

VII

5400

The IS-2M is a Soviet tier 7 premium heavy tank.

This vehicle is a modification of the IS-2, developed from the early 1950s through the early 1960s. Before the T-10's development, the IS-2 was the main Soviet heavy tank. It remained in service until the mid 1990s. The tank chassis, power unit and turret were significantly changed. Some chassis components were adopted from the IS-3, as well as the splash shields and spare parts kit. The rear machine gun was removed from the turret. It was replaced with an additional fan for the fighting compartment. All gun embrasures were sealed. In addition, the standard engine was replaced with the V-54K-IS engine. The ammo capacity was increased to 34–35 shells, while the standard gun (the 122 mm D-25) remained unchanged. However, the gun elevation mechanism was improved. Some vehicles were equipped with the TVN-2 night-vision devices. Besides this, the new R-113 radio was equipped instead of the standard one. In addition, the driver's observation devices were improved.

Player Opinion

Pros and Cons

Pros:

See IS-2 Berlin for details; only differences are listed here

• A bit improved accuracy and gun handling
• Higher ammo capacity at 35 rounds
• Has 30mm thick spaced armor protecting the hull shoulders, shoulder themselves are also thicker
• High HP pool of 1300

Cons:

• Retains the same engine despite increased weight, a bit less mobile

Performance

A plainly superior IS-2, with slightly better gun, more reliable hull armor for angling and more HP.

Historical Info

The IS project started as an improvement over previous KV designs, combining the hull developed for the KV-13 prototypes with the new KV-85 three-man turret. The 85mm gun of the IS-1, however, meant that the T-34/85 sporting the same gun performed better in almost every aspect, the IS only offering slightly better protection. Therefore, this variant, known as IS-85, was deemed insufficient for a breakthrough role. Demands for a 122 or a 152 mm gun were made (despite the ISU-152 already being accepted into service). Kotin himself proposed the use of the A-19 gun, citing its effectiveness against concrete bunkers and enemy tanks alike. The choice of a new 122 mm (4.8 in) gun was studied by Kotin’s team at Zavod Nr.9. As shown at Kursk, the 122 and 152 mm (5.98 in) guns were better suited to take on on the new German tanks, the Tiger, Panther and Elefant. It was obvious that, aside the 85 mm (3.35 in) gun, more suitable for the next evolution of the T-34, a 122 mm would be most recommended to be fitted on the new heavy tank. The gun was equipped with a muzzle brake, despite protests that it would be too noticeable when firing, and installed in a D-5 gun mount. The resulting construction was named D-2T. The T-shaped muzzle brake failed during tests, and was replaced with a "German style" muzzle brake, similar to those used on 88 and 105 mm guns, after almost fatally injuring Marshall Voroshilov during a test in the presence of the Main Defense Commissariat. Later in the tank's life, it was again replaced with a domestic design. This version, known as IS-122, started the fruition of the IS-2 tank. The effects of the new tank gun were excellent: coupled with a new pointed AP shell, it could penetrate the front of a Panther at 1400 meters, and the front of a Tiger at 1800 meters.

The Shashmurin Project

Nikolai Fedorovich Shashmurin, a well-known tank designer, was busy with a brand new IS tank, an alternative to the IS-2. Really, the only things it shared with the IS-2 were the gun caliber and its breakthrough role. It even looked vastly different. Unofficially named the IS-2Sh (Sh = Shashmurin) or simply Shashmurin’s IS-2, it was a complete redesign of the IS. It featured a rear-mounted turret carrying the 122mm gun, large single roadwheels and heavily sloped frontal hull armor. The engine was placed in the middle of the hull, with the driver at the bow cut of off from the rest of the crew. Only one drawing is known to exist of this design.

Characteristics

The plans for this project were lofty indeed: front armour impenetrable for Panther, Tiger, and Ferdinand guns at any range, side armour impenetrable at over 500 meters, an 800-1000 hp engine to get this massive armoured slab moving at 35 kph. Considering that the projected mass of the heavy tank would be 55 tons, that's not even that unthinkable. The fighting compartment was located in the rear, with an engine compartment in the center. This layout allowed to make a gun with a very long barrel, accelerating the shell to 1000 m/s, without it getting in the way of maneuvers. The transmission could be electric or mechanical. One of Shashmurin's projects was deemed viable, designated IS-2M, and began development. Unfortunately, the resources of the construction bureau tasked with the project were soon consumed by the IS-6. While the requirement for impenetrable front armour seems impossible, the IS-3 managed to pull it off in that same year.
