The IS-6 is a Soviet Heavy tank.

Plans for this vehicle were drawn up in the construction bureau of the Chelyabinsk Kirov plant from December 1943 to the summer of 1944. Further development and the construction of the first prototype took place at the Uralmash plant. However, the vehicle had no advantages over the other heavy tank designs under consideration, and its armor was seen as inferior to the IS-4 (Object 701), so the IS-6 was not selected for production.

The IS-6 replaced the KV-5 as the Soviet Tier 8 premium heavy tank available through the ingame store from patch 0.7.3. It is also currently available from the gift shop as a bundle with a garage slot all year-round. It is the cheapest of the Tier 8 premium heavy tanks. It has good armour and decent mobility, but an inaccurate gun with fairly low penetration.

The Tiger II is a German tier 8 heavy tank.

     The most heavily armored tank carrying the most powerful anti-tank gun. The vehicle's drawbacks included an overloaded suspension and engine-transmission group, as well as excessive general mass. When engaging enemy vehicles at long range, the Tiger II had an upper hand over any other vehicle in terms of the gun and armor protection. However, due to the excessive mass of the vehicle, relatively low durability of the engine and transmission, and small total number of vehicles built, the Tiger II did not have any significant impact on the course of war.

     Being one of the most feared tanks in the Second World War, The "Königstiger" (or "King Tiger", as the Allies would call it) operates average in stock configuration; but with proper positioning, it is capable of bouncing shells off its sturdy sloped front armor, provided that its lower front plate is hidden at all times as it is only 100mm thick. It sports a workable level of mobility although the weak engine makes climbing slopes very slow. All in all, this tank is a decent machine at long-range combat, with superior accuracy, good penetration, and a balanced alpha damage.

The T26E4 SuperPershing is an American tier 8 premium medium tank.

    To increase firepower, a new long-barrelled 90-mm gun was mounted on the T26E1 in January 1945. The prototype was designated the T26E4. Development was discontinued in January 1947 due to problems with the gun and the loading mechanism. A total of 25 vehicles had been built by that time, but never entered service.

   The T26E4 "Super Pershing" is a M26 Pershing with upgraded protection in the form of spaced armor scrapped off from one of the Panther tanks. It is analagous to the M4A3E2 Sherman Jumbo in that it is the up-armored variant of a mobile medium. The T26E4 does not however have access to the upgraded engine or the long 90mm of the M26 (although as of 9.17, AP penetration is similar to each other), but does have the similar but historically-accurate long 90mm tested on the tank. The turret face of the T26E4 has very good durability to complement the tough frontal hull. This makes it nearly impervious to HE shells from the front, and allows it to hold positions or assault them reasonably well.

    The armor, while very tough, is not completely immune to gunfire. The T26E4 has three large weakpoints: the turret cheeks under the "ears" formed by the additional armor welded on, the commander's hatch and the machine gun port on the right side of the hull. Shots entering here will penetrate and deal damage. However these weakpoints are covered up nicely when hull-down on a reverse slope. The T26E4 is very slow for a medium tank and is especially vulnerable while climbing hills or when it has found itself to have been flanked. This, coupled with the T26E4's sluggish turret traverse, means it will often be easily flanked, where its much thinner side and rear armor can be engaged. Likewise, this means the Super Pershing will not be able to flank most opponents, forcing you to fight enemies head-on but at a reasonable range where it will be more difficult for them to aim at the Super Pershing's weak spots. The T15E1 gun has average accuracy, and lacks in alpha and DPM to face most heavy tanks. When playing the Super Pershing, great care must be taken to aim for the weakpoints on enemy armor and to keep the three weak spots hidden or constantly moving.
