Weak Spot Guide: IS-6

The IS-6 may not seem like a tank with a great deal of armor by looking at it’s listed stats.  However, it’s armor scheme makes good use of angles and provides excellent protection overall which can fool a lot of people who do not know how to deal with one.

The index at the bottom of each picture describes a few abbreviations used and also the format in which the armor details are described in. Effective Armor (EA) refers to the overall effectiveness of the armor without normalization.

 The armor values are presented in three different scenarios for the angled view of the tank.15° frontal(75° side),  25° frontal(65° side), 35° frontal(55° side), and 45° frontal(45° side).

Frontal View #1


Frontally the IS-6 proves to be a great challenge against tier 7 and lower tanks.  This is because the weak spots most rely upon(commander cupola and lower glacis) are still quite strong against tanks beneath the IS-6. The IS-6 relies upon angles for protection and try to negate these to be able to penetrate the IS-6 in an easier manner.  The turret weak spots around the mantlet can prove to be valuable since if you are being face hugged they can be easier to hit than the cupola at times.

Keep in mind that as you get closer to the IS-6 the upper glacis/A1 gets weaker due to the angle being negated. On the other hand the lower glacis gets much stronger at closer range since it’s angle increases. The turret ring of the IS-6 is also unique in that it is covered by parts of the hull area which count as spaced armor making it extremely difficult to damage.

Frontal View #2


This frontal view simple shows the top of the turret better. The cupolas are weak to most tanks but are still 150mm thick meaning you want to hit them at the flattest area possible.  The turret roof(T2) looks like there is a flatten area along the edge but it does not have it’s own hit box.  Due to the 85 degree angle across the entire roof you will simply bounce off even though it looks flat unless your tank is taller than the IS-6.

Side View


The side of the IS-6 fools many players.  At first glance players might be drawn to shooting the flat area(LSH#1) which is covered by spaced armor but this area is actually stronger than the upper side hull area.  Aiming beneath the spaced armor portion also proves to frustrate many since there is only a thin strip beneath it which has hull armor behind it(LSH#2).  LSH #2 also is only capable of being damaged by non-HEAT/HE shells since it is at 70 degrees. If all else fails hitting the flat portions of the turret side or the LSH#3 areas at each end of the tank can be done with some careful aiming.

Rear View


The rear of the IS-6 is simply if you remember to hit the central area of the tank in the hull and turret.  The area here is the weakest and as you progress towards the side of the tank it gets much stronger.

Angled View


When an IS-6 driver angle they change the armor values immensely. At low angles you will want to stick with shooting the LFG/A1 area but as they continue to angle the LSH#3/USH#1 areas become the prime weak spots. Just remember that the IS-6 relies on angles and try to aim for the flattest parts available(the ones pointing at you) and you will be alright.  For turret armor values reference the frontal and side views of this guide.

  1. Thank you! I have a lot of trouble going against that thing with my tier 7s and 6s.

  2. Hi! i thinking to buy is-6 and liked to ask u opinion are is-6 better than t34..Ofc i know they play styles are different but..still want opinions to make sure.. :)

    • Both are good. Get the one you have a crew for so you can train them in it.

      IS-6 is more up in your face, T34 is more mid range.

    • I own t34 I want to buy IS 6 because of its fun factor, t34 sees tier 10s regularly it was fun at first to pen them with 248 mm penetration but with 12.5 secon reload and 400 damage tier10s are not a place for this tank, Is 6 however is really good with incredible armor angles and bouncing, also its pen and damage are really good for its tier and enemies she faces, I would say IS-6 , or maybe 112 that is new, also think about crew training too, with is6 you can train your is7 and is4 crews or at least part of them 😀

  3. Do yourself a HUGE favor and GET THE IS^ OVER THE 112! – While the 112 MAY have better paper stats, and from straight on – with lower glacis ENTIRELY covered (as it is ONLY 80mm at 45 deg – I can pen it EASY in my E-25) Which brings me to another point – side armor. In my E-25, I have caught 112’s by the side and I can track and damage them easily every shot without any APCR. When i see the broad side of an IS6 in the E-25, I am lucky to track them and do even 1 or 2 damaging shots before having to high-tail it out of town. And that speaks VOLUMES about the 112’s general armor vperformance vs. the IS6. As unlike the IS6, even at close range it is easy for any gun with 150+ avg pen to get through the lower glacis. The IS6 on the other hand has 120mm at 50 deg lower glacis which at close ranges (and even mid) is basically impenetrable, and even if you DO penetrate there, I have found you are lucky if it does ANY HP damage – though it is easy to track an IS6 in such a way. The 112, unless fully hull-down is an easy target from EVERY angle, this is pretty much opposite from the IS6, NTM the IS6 has higher HP/ton and is more maneuverable, AND has a good bit higher rate of fire at 5.13 RPM rated. With Vents, rammer and BiA (like I have – along with vert. stab. smooth ride & snap shot) I get a round every 9.65 seconds! An AMAZING 6.22 rounds/min!!
