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.

The IS-7 is a Soviet tier 10 heavy tank.

Development of the IS-7 started in the spring of 1945. Prototypes successfully underwent trials in 1946 and 1947. However, the IS-7 never saw mass production.

With it's well angled "pike-nose" frontal armor layout and a rounded, highly sloped turret front, the IS-7 is one of the toughest nuts to crack when engaged from the front. If positioned behind a piece of cover which shields it's lower glacis plate, it becomes a hardened object with so few weak points that successfully damaging the tank turns into a most frustrating experience. Therein lies a weakness, however - the IS-7 cannot angle it's armor, because if it does, the sloping of the frontal plate will become significantly worsened and enable most guns to punch through with relative ease. The side armor of the tank is comprised of spaced plates which are not only small but angled as well, making even perfectly landed shots to the hull's midsection fail to do any sort of damage at times. The rear armor is quite thin, however, and will rarely deflect even lower tier guns. The IS-7 mounts a very potent 130mm S-70 naval cannon as it's main gun. While it's potentially high damage output can seem quite formidable, the gun itself is largely inaccurate, has a rather long aiming time, takes awhile to load and is actually much less effective than it seems. Nevertheless, at close and medium ranges the gun can still inflict very serious damage. Sustainability of said damage is difficult, though, due to the aforementioned long reload and aim times.

When compared to it's Soviet counterpart, the IS-4, the IS-7 instantly feels more responsive and agile. It has a higher top speed and can change direction with much greater ease. The IS-7 also isn't quite as well rounded as the IS-4, relying mostly on it's incredible frontal armor to deflect and absorb incoming damage as opposed to the IS-4's effective all-around hull armor. Due to the side armor's spaced layout, however, side scraping is a very viable tactic and should be utilized when possible. The 130mm gun is not as accurate, though more damaging, as the 122mm gun of the IS-4 and will not handle as well either. Overall, the IS-7 is definitely an up-close-and-personal fighter and should be used as such. Your teammates will rely on you to take and deflect the majority of incoming fire while they in turn support your advance and use their (hopefully) more accurate guns to assist in whittling down the enemy team. Expect to do some heavy lifting when driving the IS-7 and use it's key advantages to fight on your own terms and dictate the flow of the battle, improving your performance and probability of success.


The IS-7 marks the end of its Soviet heavy line.

Player Opinion

Pros and Cons

Pros:


  • Amazingly thick and angled frontal turret and upper hull armor
  • Side armor is very angled and spaced; difficult for HEAT and HE shells to penetrate
  • Hard hitting main gun
  • Excellent top speed and decent gility for a heavy tank
  • Lower glacis plate not included, very small frontal armor weak points which are difficult to hit


Cons:


  • Very low DPM, one of the worst at tier X
  • Premium APCR have very low penetration
  • Poor accuracy and one of the longest aim time of all tier X HTs
  • Poor hull and turret traverse speed
  • Extraordinarily high terrain resistance making the top speed not easy to achieve


Performance

IS-7 is a fast heavy tank that delivers mediocre damage while being hard to kill due to its heavily sloped front armor. The IS-7 has some of the best angled frontal armor in the game, however this is somewhat nullified at close range by the equally thick but much less angled lower plate. All these strengths come with a weakness; the IS-7's main gun, while having the same listed accuracy as the E-100's 15cm, in practice it seems to be worse at actually hitting the target, let alone hitting a weakspot, thus requiring the player to get fairly close to their target in order to lessen the impact of its poor dispersion values. This in turn makes you a much easier target to hit as well. The IS-7 uses the 130 mm S-70, which has better alpha damage than the 122mm M62-T2 mounted on IS-4, but worse stats elsewhere. The main difference between the IS-7 and the IS-4 is that the IS-7 is much faster, with a top speed of 60 km/h (though this is difficult to reach under normal driving conditions), as well as having good turret traverse.

However, these sloping plates also add a disadvantage: You cannot angle the frontal armour of IS-7 as you expose the well-sloped-but-weak armour plate to the enemy, the effective armour when fighting angled drops a fair amount, allowing tier 8, 9, and 10 guns to punch through if they strike at a shallow enough angle to the plate. This in turn makes your lower plate incredibly easy to penetrate as it is just as thin as the upper plate but with far worse sloping. When fighting one at an angle, prefer its flatter front armour sections than is angled side armour, or shoot the sprocket, dealing damage and throwing off the track. If fighting in an urban environment with many street corners that force you to turn to shoot you opponent, it's advised that you bait them into shooting your thick and spaced side armor by sidescraping, then returning fire as they reload. Or if your weak lower hull exposes to enemy fires, try to wiggle or shake it so that it's harder to penetrate. This can even sometime bounces tier X TD's shots. Once you mastered this tank and know how to hide its weaknesses well, it can be a very fearsome tank to your enemies, no kidding.

Historical Info

The development of the IS-7 started in the Spring of 1945. Prototypes were in trials during 1946 and 1947. By 1948, the IS-7 heavy tank was developed. The IS-7 model 1948 variant had a weight of 68 metric tons and was armed with the 130 mm S-70 naval cannon (7020 mm long barrel) with autoloader and stabilizer, infrared night scopes, 8 machine guns, armor from 220 to 300 mm thickness', and 60 km/h roadspeed.

Only three were built and it was the largest tank ever produced by the USSR. In spite of its weight, it was easy to drive due to numerous hydraulic assists. The loaders noted that the IS-7 was comfortable and that the autoloader was easy to use. Its armour was not only immune to the Jagdtiger's 12.8 cm L/55 PaK 44 but was even proof to its own 130mm. Due to the reasons unknown, most likely because of the political repression against Leningrad bosses in the same year, the tank never reached the production lines. The tank housed a crew of five.

It must be noted that the Slostin gun was to be installed as its AA armament.
