Player Opinion

Pros and Cons

Pros:


  • Excellent armor on the front
  • Spaced armor on the sides
  • Nearly invincible when face hugging
  • High top speed


Cons:


  • Poor gun depression.
  • Slow turning and low acceleration
  • Horrible aim time AND accuracy.
  • Frontal armor is tough, but relies on slope rather than thickness. If angled or shot from above front can be penetrated.
  • Extraordinarily high terrain resistance in game means it will never reach its top speed on anything but downhill


Performance

It's not fast and delivers mediocre damage while being hard to kill due to its heavily sloped front armor. The IS-7 has some of the best sloped frontal armor in the game, however this is somewhat nullified at close range by the equally thick but much less sloped 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, you can expect 30-35kmh in most cases), 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.


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. Although it was in many ways an innovative design, it was never accepted for mass production due to its cumbersome size and the very impractical layout of its fighting compartment. The tank housed a crew of five.

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