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 you a much easier target to hit as well. 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. 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.

It's not fast and delivers mediocre damage while being hard to kill due to its heavily sloped front armor. Extraordinarily high terrain resistance in game means it will never reach its top speed on anything but downhill.If angled or shot from above front can be penetrated. Frontal armor is tough, but relies on slope rather than thickness.
