Weak Spot Guide: E-100

The E-100 is a double edge sword for it’s drivers when it comes to the armor.  The top half of the tank is very well armored(aside from the turret sides/rear if they aren’t angled) while the lower half is not as well protected.  This guide will go over the effective armor of the E-100 from a few different angles and point out a few other small spots to aim for in each situation.

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.

Frontal View


Frontally the E-100 is no slouch when it comes to armor besides the lower frontal hull(LFH) which really hinders it’s capability of deflecting many incoming rounds when facing directly at an enemy.


The Upper Frontal Glacis is 200mm thick and at 60° making it quite difficult to penetrate since it’s effective armor is 400mm . Generally it is best to simply avoid shooting here and go for the lower glacis.


The Lower Frontal Glacis is 150mm at 50° making it a gigantic weak spot for most tanks facing the E-100 since it’s effective armor is only 233mm. Do not shoot here however if you are within 50m of an E-100 as the angle is greatly increased and you will auto-bounce.


The Frontal Turret armor is an impressive 250mm thick at a 30° making it a tough nut to crack. It’s effective armor is 289mm  making it weaker than the Upper Frontal Glacis and vulnerable to gold rounds or tier 10 tank destroyers. In all other situations though its best to avoid shooting the frontal turret.


The view port sticking up out of the top of the turret is easy to damage however does not do HP damage the majority of the time. The “police bar” running along the top used to be a very exploitable weak spot as well but has since been fixed. Shooting at it will not get you very far in doing HP damage.


This flat piece of armor running along the entire bottom portion of the E-100’s turret is a weak spot for those with 250mm+ penetration.  The armor here is no as weak as most other turret rings on other tanks but rather hovers around 245mm effective armor. Useful for those times when you are to close to shoot the lower frontal glacis.


The turret mantlet and gun are very tough and should be avoided.

Angled View


An angled E-100 much like the E-75 is a very difficult opponent to face and it’s weak spots that are easy to hit from the front or sides become much tougher.  The armor values are presented in three different scenarios. 25° frontal(65° side), 35° frontal(55° side), and 45° frontal(45° side).


The Upper Frontal Glacis becomes even more badass when angled.


This once easy to penetrate weakspot becomes a much harder place to penetrate as the angle increases. Still remains a viable weak spot however at lesser angles.


The Upper Side Hull (#1) is the most difficult place to penetrate the side armor as it is the side 130mm/0° armor with a 60mm/60° spaced armor plate on top of it.


Moving down on to the Upper Side Hull (#2) it becomes slightly easier… However the armor is still 120mm/0° with a 60mm/0° spaced armor plate on top of it along with track armor.


The Lower Side Hull is simply 120mm/0°  with additional track armor with no spaced armor on top of it.


If either the frontal or side armor of the turret angled it becomes very difficult to penetrate due to it’s thickness and angles already present. Avoid shooting the FT like before, and only shoot the ST if it is not angled.


Same as the frontal view both locations can be penetrated but HP damage is highly unlikely. The view port is your best chance but typically only crew/module damage occurs.


Depending on where the turret faces this location can be penetrated with 250mm+ penetration guns if this location is not angled.

Side View


 The overall armor of the E-100’s side armor is rather poor while facing the typical tier 9-10 guns on it’s opponents but there are still a few spots to hesitate shooting at.


The top portion of the USH is 130mm/0° covered by 60mm/60° spaced armor making 240mm EA. Tier 10 tanks may bounce with a very low penetration roll and tier 8/9 tanks struggle a bit more against this area but it is easy enough to just aim at the weaker armor around here. The lower portion that is 120mm/0° covered by 60mm/0° spaced armor/track armor making it 205mm of EA armor which is easy for most tanks facing the E-100 to penetrate.


The Lower Side Hull is the weakest part of the side armor of the E-100 since it is simply 120mm/0° with no spaced armor(and track armor) allowing low penetrating guns to cut through whereas in other locations they cannot.


The Side Turret armor is 150mm/30° making it 173mm EA / 165mm AP. Very easily damaged while flat.


These locations become incredibly difficult damage even for crew/module damage from this viewpoint.


The small gap behind the gun mantlet can be damaged by guns with over 180mm penetration.


The turret ring section on the side is still roughly 245mm of effective armor making it stronger than the side and turret armor around it.  Still damageable by tier 10 tanks and there if you absolutely need it but not the best option available.

Rear View


The backside of the E-100 is very easy to handle. It’s Rear Hull Armor(RHA) is 150mm/30° only making it 176mm EA.

The Rear Turret armor(RT) is only 150mm/20° making it 160mm EA.. I included it as orange since the angle on it will most likely be shifting and as the angle increases the armor will become harder to penetrate for lower penetration guns.

A1(circle on rear of turret) is easier to damage than the surrounding turret armor and tanks such as scouts should aim here. A2 on the other hand is difficult to penetrate since it is a highly angled plate leading the A3 which is the 245mm effective turret ring armor should be avoided only because the armor around it is much easier to damage.

    So with the new Super Heavy spall liners in 8.6, how safe is the E-100 from arty splash damage?

    • I generally do not worry about artillery in tanks like the E-100, Maus, KV-4, etc. when I have the spall liner on. Usually only direct hits and/or penetrations will cause enough damage to warrant worrying about artillery.

  2. Hi all
    I have to disagree with weakspot A2 on the turret ,it is very tought .. I have tried it with jgpze100 3 times from 20 to 4 meters and NO pen. It is easier to pen FT armor

    • It might be labeled yellow but that merely means it is weaker than the red locations. It isn’t “weak” by any means but it is there if you have no where else to shoot.

  3. Not to be an ass – I love your guides and find them VERY helpful. But in the interest of being even more helpful to players – it seems for this tank (as well as several others) you fail to mention that the E-100 has a SOLID 40mm of tracks – as in there is nowhere that you can shoot where the tracks cover without having to first penetrate the 40mm of its tracks. So on the weakest part of the side hull I would posit that you would need to penetrate a minimum of 40mm of tracks (which I believe is counted as a type of spaced armor as well?) – even if not, that would still mean the weakest point in the E-100’s side hull is still 160mm thick total. And with the skirt – even on the flat part it would then add up to a total of 220mm needed to penetrate from 90 deg or 0 deg depending on which definition you use. (WOT goes by 90 deg being flat – or perpendicular)

  4. I have to say that the only place i can get consistent pen on the fron of the E100 turret is bottom left/right corners, i have not tried the gap between the turret and the hull.

  5. Similarly, the Maus has 25mm wherever the tracks are, and both the IS7 and IS6 have a solid 20mm wherever the tracks are present.

    I have gotten all this information from collision models – in which it shows exactly what armor vales are where. Not ALL tanks have solid tracks, but the ones I mentioned as well as many others seem to have a solid 20+mm of armor from the presence of the suspension system.

  6. Oops I meant to say WOT goes by 0 degrees being flat or perpendicular. I mixed that up by accident.

    I know collision models do not tell the whole story – but it does seem to hold true on my E-100, IS7, E50M (which has 25mm of solid tracks + some small amt of side-skirt!) and IS6 – as when people shoot at my variously angled suspension parts they often fail to penetrate for HP damage – most often when shot in the middle of my tracks I find I end up with just suspension “damage:” – which I suppose slows my turning speed and whatnot but is barely an inconvenience. For example, in my most recent IS6 match I was shot a total of 7 times for a total potential damage of 1800 HP, only 2 were marked as penetrations in post battle – but I had taken 0 HitPoint damage! In fact i was never even tracked! All i got was damage on both sides of my suspension! My repair bill subsequently was only 550 credits lol….

    But that goes STRONGLY to make a case that solid suspension systems greatly augment overall armor values! As in that case I was “penetrated” twice in basically the middle of my IS6’s suspension, resulting in 0 HP dmg and only track “damage” – not total tracking.
