Weak Spot Guide: IS-7

The tier 10 Russian heavy tank IS-7 has a formidable armor scheme  that relies heavily upon compound angles and trickery to protect it.  The trick to facing an IS- is to try and aim for the spots that are not angled heavily since it gives you the best chance to punch through it’s armor….but it is not that easy in some areas since the armor has multiple hidden layers.  The driver’s port and top commander hatches also are unlike many tanks in the way they are modeled which can lead you to be puzzled when you cannot damage them easily.

Frontal Views



Frontally the IS-7’s armor has both very thick places and heavily angles places that give it a very tough frontal armor scheme.  Like most tanks the main weak spot is the lower frontal glacis (LFG) and there are also some weaker parts near the mantler on the frontal turret armor(FT #1 / FT #2).  However, the driver’s port located under the gun is deceivingly strong and the commander hatches(the yellow strip on the first image and more specifically the second frontal image) are also designed to fool you.
Looking at the IS-7 the left commander hatch(A3-A5) is tougher than almost any other commander hatch you will find and also has a gigantic view port on it that takes no HP damage.  The right commander’s hatch on top(A6-A7) only takes damage if you shoot the small “lip” behind it unless if you are shooting directly down from above.  These two spots are not very apparent but are your best choice if you are stuck shooting at an IS-7 that is very close to you.
The actual hull armor is very tough aside from the obvious lower frontal glacis(LFG) weak spot.  The upper glacis’ are all heavily angled and while they are only 150mm thick are extremely strong due to the angles.  If you are able to negate the angles by shooting down while close/above an IS-7 they become a better option than the LFG.  The driver’s hatch in A1/A2 is very strong as well since it’s angle actually increases when compared to the glacis plates around it.

Side View

IS7_Side (2)

The side of the IS-7 is easy to figure out after you loose enough of your shells aiming high on the side hull armor or the turret.  The USH #2 area has a 20mm flat piece of spaced armor on it which hides the reverse angled hull armor behind it which throws off a lot of people shooting at the side of the IS-7.  All lower side hull armor locations are weak since they are not angled and are not very thick.  The side turret has several different areas(and that 20mm spaced armor box) that are tough for non-tier 10 tanks to penetrate but the main rule of shooting at the least angled part holds true here.  Any areas without titles assigned to them are not worth trying to shoot at since they are stronger than the surrounding armor.
Ammo racks are located behind USH #1 starting at ST #2 and ending at ST #3.  There are also larger ammo racks sitting beneath the mantlet starting at USH #2 and ending just above the tracks.

Rear View

The rear of the IS-7 is not protected well aside from the outer portions that are angled heavily.  Stick to aiming at the center of the IS-7 and you’ll be find.

Angled View

Usually IS-7 drivers do not angle since their armor scheme focuses on keeping the frontal armor pointed directly at their opponent.  This keeps those compound angles on the frontal armor and thus makes the IS-7 difficult to damage aside from the lower glacis.  If however an IS-7 driver actually does decide to angle then you should still stick to either the lower frontal glacis or if they angle heavily switch over the lower side armor.  The ammo racks are located just behind the driver(under the front of the turret) and behind USH #1.  Aim here and make them regret angling.

    I really like your Videos and this blog. I hope you make more weakspot guides, they help a lot more then a easy hitzone skin. Thank you for your good work.

    • Thanks! Glad you enjoy them. I plan on putting them up every few days. Trying to alternate between guides, weak spot guides, replays, tips as each different type takes a certain touch to put together.

    Thanks man, your is-7 and is-4 hitspot guide where exactly what i was looking for 🙂

  3. I have read all of your weak spot guides and think you have done a great job. Thanks alot.

  4. Just a quick thx for helping, always find myself coming back here as i move up in class, as these guides help. Keep them coming and once again Thank-you.

    I think something has changed regarding the “weak points” in Area Two in the first photo. I don’t know if it’s the normalization changes, or what, but some clanmates and I went into a training room a couple days ago and at close range, head-on, we *repeatedly* bounced shots from each other’s IS-7s from that area (right under the headlights). We each fired at least four standard AP rounds at that spot (so a total of at least 12 rounds, maybe more, at a range of about 50m) and I don’t believe any of us got a single pen..

    The lower glacis is still very weak, though.

    • This guide is old(can see from the layout) so some spots are a tad off. At close range though the shoulders do increase in armor effectiveness though due to the angle.

  6. The driver’s hatch is a zero damage pen zone.

  7. Hey I have been playing with this tank for awhile now and I noticed that when I’m side scraping, this E75 manages to pen my side armor where the spaced armor is… I have no idea he penetrated that zone at that angle… But great guide!

  8. what is goin on with is7. im shooting gold with my t-54 on its side, with no angle or 90deg. and cant do damage? area two and three

  9. now i can pen the IS – 7 , thank god lol XD.

  10. i cant play it anymore because the full screan mode messed the
    F***ing game.thanks for your advice though 🙂
    When i get a nother account, i could use your information about the
    weak spots. Thanks! XD.

    Cody, I am a 47% player for a number of reasons but a big part of that is never learning weak spots. Thank you for your time and expertise.

  12. dude how come my Is7 gets penned on the side while side scrapping?? doesn’t it have 150 mm?

  13. who did this garbage?? you better update this cus my IS7 always gets penned on the gun mantlet so IT IS NOT IMMUNE!!

    • It is from a head on angle. If the enemy is slightly off to your side however it can be penned but not easily.

    What is the thickness of the IS-7 Mantlet is ?

  15. wlskrkejs dlsrks | February 26, 2015 at 6:38 am |

    Effective armor thickness of the IS-7 Mantlet side is is the mind?

    • It doesn’t matter, there isn’t anything behind it(if you are looking at the side). Frontally it is 350mm around the gun and after that it is immune on the sloped sections.
