== Description ==

[[File:GarageImage KV-1(L-11).jpg|420px|thumb|left]]
{{break}}
The '''{{specs|name}}''' is a rank {{specs|rank}} Soviet heavy tank {{Battle-rating}}. This tank was introduced during the closed beta testing for Ground Forces before [[Update 1.41]]. The KV-1 L-11 is the first unlockable Soviet heavy tank which boasts raw firepower and armour at the cost of mobility.

The first heavy tank available in the Soviet branch. It's slow, difficult to maneuver and heavily armoured, and mounts the same gun of the [[T-34 (1940)|T-34 1940]], sharing its awful penetration. In Rank II battles, this tank is tough to penetrate so you can lead the assault and absorb shots that will quickly destroy your lighter and better-armed teammates. It's better to prefer short-range engagements, and you must aim for weak spots, but your best weapon is other players, so act like a steel wall and cover other tanks with better guns.

=== Survivability and armour ===

'''Armour type:'''

* Rolled homogeneous armour
* Cast homogeneous armour (Gun mantlet)

{| class="wikitable"

! Armour !! Front !! Sides !! Rear !! Roof
|-
| Hull || 75 mm (31°) ''Front plate'' 70 mm (72°) ''Front glacis'' 25 + 70 mm (7-71°) ''Joint plate'' 75 mm (26-51°) ''Lower glacis'' || 75 mm || 60 mm (13-89°) ''Top'' 70 mm (14-57°) ''Bottom'' || 30 mm

|-
|}
'''Notes:'''

* Suspension wheels are 20 mm thick, tracks are 30 mm thick.
* Roof armour is quite excellent. 30 - 40 mm is nothing to ignore. It will reliably protect from most autocannons. Although aircraft with unique diving capability and +0 mm arms may still pierce it. More importantly, it makes the vehicle quite resilient against rocket strikes from vehicles such as the [[Calliope|Calliope]].
*The lower glacis, unlike most other tanks, is not a weak spot! It is including your own turrets height significantly better angled than the upper frontal plate. Further, neither the MG port nor the drivers view slit are weak points. Discard them as targets.
* Gun mantlet is an extra 75 mm bolted on to the turret, with some parts with an additional 90 mm added instead. This results in a spaced overlapped part with ~150 mm. Only the cheeks left, and right of the mantlet bulges should be shot! However, these areas are quite small and easily missed, if the turret is traversed.

== Usage in the battles ==

The first thing to know about the tank, just because it's a heavy tank ''does not'' mean you should charge headfirst into the enemy. While it may look intimidating as you watch the enemy's shells deflect off your vehicle as you move slightly forward to their front lines, you risk getting flanked as moving forward gives the enemy enough space to get around and hit you in the vulnerable rear area. Try to avoid letting the enemy get close enough to catch your turret ring and destroy each of your crew from there. Thankfully, the turret ring is quite a small target, and will be difficult to hit from far away. Despite the 75 mm all-around armour, don't think for a second that you are invulnerable and play smart still. Also, angling is quite important, as many of the Axis long-barreled 75 mm will penetrate you.

Make sure that you have a few teammates that are with you when playing the KV-1, as your gun will struggle to penetrate common foes such as the [[M4|M4 Sherman]] and the [[T-34]] frontally. With only 78mm of penetration at point-blank, it is necessary to aim for your opponents weakspots. However, the post-penetration damage is amazing, and a shot that penetrates will most likely kill the enemy.

One of the more common and dangerous enemies this vehicle will face is the [[Pz.IV F2|Pz IV F2.]] The Panzer IV F2 has thin armour, but the long [[KwK 40 (75 mm)|75 mm]] cannon can easily pierce the KV-1 armour if it is not angled properly. The penetration for the PzGr 39 Shell, which is an APCBC and the stock shell for the Panzer IV F2, at normal combat ranges of 100 meters and 500 meters has 133 mm and 121 mm respectively. Another dangerous enemy is the [[StuG III F|Stug III F]]. It has the same 75mm as the Panzer IV F2, but lacks a turret, making it harder to hit. Also, it is more well armoured compared to the Panzer IV F2, and has some sloped armour plates in the front. Try to hit the two non-sloped spots near the driver and the machine gunner, or flank around and hit their weak side armour.

===Counter-tactics===
''Never'' charge into a KV-1 unless you are also playing as a heavy tank. The L-11 is a low-quality gun but can do devastating damage at short range. As a light tank, medium tank, or tank destroyer, ''always'' sneak around the KV-1 and get in shots from the back or side. The KV-1 has a slow turret traverse and flat side armour, making it especially vulnerable to flanking.It is not advised to engage with a KV-1 at all if you are playing as an SPAA.

As a heavy tank, if your gun is capable of penetrating the front of the KV-1's frontal armour, aim for the lower middle of the upper glacis, where the large ammo rack is located. If the shot penetrates, it almost guarantees a destroyed KV-1 as the ammo rack is huge.

As a light tank, medium tank or tank destroyer/SPG, use the advantage of cover (building, hill, trees, etc.) to flank or get behind a KV-1. It will be hard-pressed to turn quickly enough to angle its near-impervious frontal armour towards you. If you are not confident in your gun's ability to deal significant damage to the engine block or ammo racks, it is advised to fire at the tracks and disable the tank before rushing up to it and firing directly at the back. Shooting at the rear of the turret is also an option to attempt to hit one of the ammo racks on either side. However, smarter drivers will empty their turret of ammunition, so firing at the turret will not always work.

===Modules===
As usual, ''Parts'' and ''FPE'' first. ''Tracks'' is a good additional choice, a frequently targeted module. Also, it increases your turning capability a lot. After these, research ''Adjustment of fire'' and ''Brake System'', because the accuracy of the L-11 cannon is slightly increased, even though it is still subpar. The suspension is useful for firing on the move, something particularly useless for a slow, heavy tank. Braking quickly and being able to fire a more accurate shot proves to be much more efficient. The BR-350SP does not see any use. The small gain in penetration is offset by the lack of any HE filler, and the round should be ignored entirely. Afterwards, all Tier III & Tier IV upgrades are equally useful.

=== Pros and cons ===

'''Pros:'''

* All points of armour are better than good at its rank
* Angling your hull makes it virtually immune to most guns it faces
* Virtually no weak spot except the small turret ring
* Gun does decent damage upon penetration
* Heavily armoured for a Rank II tank
* One of the few Russian tanks that have a crew of five
* Excellent rate of fire, useful for short-range engagements
* Quicker and better armed than the other first-rank II heavy tank; the [[Matilda Mk II|Matilda II]]

'''Cons:'''

* L-11 gun is very inadequate for its battle rating
* Low speed, typical for heavy tanks
* Slow turret traverse, if you need to change targets quickly you must rotate both the turret and the hull
* No neutral steering - making turns, especially when playing as the stock KV-1, will decrease your speed dramatically
* Penetration shots from the sides and below the turret are typically catastrophic
* Heavy and slow, you can't relocate quickly, and you are vulnerable when climbing hills
* Later variant of the Panzer IV can easily penetrate your armour, even from the front
* Large fuel tanks lined up on the side
* Cannot reliably compete with other heavy tanks in its BR range
* Most British tanks can penetrate your armour even from long range
* Trying to knock out another KV-1 L-11 is just a waste of shells and time

== History ==

===Development===
The start of the KV-1 heavy tanks began after the heavy tank [[T-35]]'s flaws came to light. Designers were ordered to draw up new designs to become the basis of a breakthrough heavy tank needed for the Soviet doctrine. This made for a tank that was heavily armoured, but not very mobile as it was to be for siege warfare. The designs offered all had heavy armour, wide tracks, and used the torsion-bar suspension. The designs were the [[SMK]], T-100, and what would be the '''KV tank''', which was named after the then Soviet Defense Commissar '''K'''liment '''V'''oroshilov.

During the developmental progress, the prototypes of all these heavy tanks were made, and the Winter War with Finland was on its way. The Soviets sent these tanks into Finland for combat testing, to which the KV design outperform in every way with its superior armour and firepower. The armour on the KV tank was impenetrable by a tank cannon in service and most anti-tank guns as well; the 76.2 mm cannon also gave it a colossal firepower boost compared to the usual 37 mm in use by other countries. However, the design was found to be challenging to steer, the transmission was unreliable, ergonomics were weak, and vision was limited, plus with its 45-ton weight, it was a weighty tank for its time. In truth, while formidable in power and protection, courageous crew member willing to curse the name would speak out about the trouble the KV tank was. The first variant of production before World War II broke out was the '''KV-1''' model. The first model production was equipped with the L-11 cannon, but this was deemed insufficient in performance and was later replaced in subsequent production models by the improved [[KV-1 (ZiS-5)|F-34, or the ZiS-5 cannon]].

===Combat usage===
When Germany invaded the Soviet Union in 1941, the Red Army had 508 of the KV tanks. With that many KV tanks available, the Russians shocked the German forces as their anti-tank and tank forces had few weapons capable of defeating it, having to rely mostly on the 88 mm Flak guns and the 5 cm Pak 38 with APCR rounds. But by 1942, Germany fielded large amounts of long barreled 50mm and 75mm cannons in both tanks and towed format, making the KV lose much of its armour advantage.

Perhaps the most memorable moment of glory for the KV-1 was at Krasnogvardeysk near Leningrad on the 19th of August 1941 when 5 KV-1s, led by Lt Zinoviy Kolobanov, ambushed the German 8th Panzer Division (a light panzer division consisting mainly of Panzer II, III and 38(t)). But there are some contradicting stories about what happened, and even if it indeed did happen. One story that supports the claim goes like this: each of the five KV-1s was hiding at different locations, came out one by one to fire at the incoming German tanks, then retreat before the next tank could come out. Such tactic boxed an entire tank and ended with 43 tanks destroyed before the KV-1 tanks retreated from running out of ammo, all in a span of about half an hour. During this battle, one of the KV-1 tanks was struck 135 times with no penetration. For their feat, Lt Z. Kolobanov and a few officers were decorated with the Order of Lenin and Order of the Red Banner medal.

The KV-1 continued to serve until the end of the war, though in dwindling numbers as they were lost due to mechanical failures, combat, and being superseded by more modern tanks. Some KV-1s built in 1941 still saw service in 1944 at the Leningrad front before being replaced by IS-2 tanks, then they saw service in Manchuria in 1945 before retired altogether at the end of World War II.

===Variants===
Many variants of the KV tank would be produced in the span of World War II as the Soviet try to keep it in production as long as possible, the initial version was called the '''KV-1''' and remained most part as the main Soviet heavy tank for the first part of World War II. A bunker-buster variant mounting a 152 mm howitzer after experiences in Finland brought the monster '''[[KV-2 (1939)|KV-2]]''' assault tank, which is very turret heavy that it must be on a flat surface to properly rotate. After complaints of its mechanical issues and lack of performance compared to the lighter [[T-34 (1941)|T-34]] medium tank was heard, the factory updated the tank, thinning its armour, and adding a commander's cupola with all-around vision blocks, so in 1943 it was designated as the '''[[KV-1S]]'''. But the KV-1S introduction was a little too late as then the better German tanks such as the [[Panther D|Panther tanks]] could knock them out with ease. An attempt to up-gun the KV-1S was to give it the 85 mm D-5T gun then in use on the [[SU-85]]. This variant was called the '''[[KV-85]]'''. Though it was seen favourable for a nice increase in firepower among the armoured forces, soon even the lighter T-34 began mounting the 85 mm gun as the [[T-34-85]]. It was determined that the heavy tank would have a much bigger gun than the medium tanks, but at the time the KVs were falling out of favour in preference to the newer [[IS-1]] and [[IS-2]] heavy tanks coming into service, which was based off the ''KV-13'' prototype tanks developed in 1942 as a medium tank.

===Survivors===
Several KV-1s survive after the war, most as monuments, but also in museums. Only one genuine KV-1 was restored to running condition in Russia after it was found in the bottom of the Neva River.

=== In-game description ===
The first clashes with Spanish nationalists armed with light anti-tank weapons made it clear that a new heavy tank with cannon proof armour had to be created. The heavy tank's design began at the end of 1938.

For 1940, the mass-produced KV-1 was a truly pioneering innovation, embodying the most advanced ideas of its time: individual torsion-bar suspension, reliable cannon proof armour and a single powerful universal weapon within a classic layout. This was the first time such an arrangement was used on a Soviet mass-produced heavy tank, which meant that the KV-1 received the strongest defences and most potential for modernisation. The tank's armoured hull was welded from 75, 40, 30 and 20 mm thick rolled armour plates. The KV-1 was equipped with a 500 hp B-2K diesel engine and a 76.2 mm L-11 cannon with an ammunition complement of 111 shots, in addition to three 7.62 mm DT machine guns. One was paired with the cannon, while the others were placed on the bow and stern in ball mounts. When necessary, the machine guns could be removed and used outside the tank.
The KV-1 tanks made their debut on the Winter War front. The tank successfully passed its trial by fire. No enemy anti-tank cannon was able to destroy it. Many times, the new vehicles survived battle not only with several but with several dozen German tanks.

The tank had some serious drawbacks: it's poorly designed transmission and air filter, insufficiently durable tracks and road wheels, a crowded fighting compartment and poor vision. The engine and transmission often broke down during intensive use. The tank's 7-tonne turret also caused many problems. Its weight lead to rotation issues related to the high force placed on the aiming mechanism levers and the low power of the electric motors.

== Usage in battles ==

The IS-4M is a direct successor to the [[IS-3]], and it features even more armour, so much armour that some APDS and APFSDS cannot penetrate its UFP and most of the turret, needless to say this tank is practically invulnerable to conventional rounds from the front. Unfortunately the gun remains the same 122 mm D-25T that is featured on all IS-series tanks from the [[IS-2]], and at Battle Rating 7.7 it isn't enough sometimes, while other times a weird bounce can still lead to some good hits. Overall, though, this tank feels much better at its Battle Rating than the aforementioned [[IS-3]], which has a huge shot trap.

=== General Gameplay ===
The playstyle is slightly different from its predecessor, as angling can work - it just needs to be done carefully. The frontal side armour is actually thicker than the front, so a slight angle will even-out hull armour all around (in a best case scenario it can get to 275&nbsp;mm, or just slightly more). Also, the IS-4M is less mobile, because it's heavier - all speeds are dampened and mobility is heavily impaired. However, if you've played the stock [[IS-3]] this tank will feel a bit better.

'''Arcade Battles'''

The IS-4M will show a lot of red and yellow on the reticle when a player looks at it in Arcade. Only some HEAT and APFSDS shells can penetrate this beast frontally, and damage will only be substantial if the player takes their time to aim at the important components, because some shells will penetrate but their effect will be minimal inside the tank. However, there is little the IS-4M can do to make it harder to be damaged, because there are practically no weakspots to hide, and wiggling will not stop top rounds from penetrating.

In Arcade Battles, the improved speed should be used to rush any lone enemies and objectives. When this tank is at speed, enemies will often shoot the biggest part they see - the UFP, and many shots will bounce or not penetrate if they hit at an awkward angle; but even if they do penetrate the UFP, the IS-4M will be able to return fire because only the driver and possibly the transmission are knocked out. Very rarely will the IS-4M get one-shot through the UFP. Again, being at speed is being protected, and it is a big surprise to many enemies when a heavy tank drives around a corner at high speed - giving you extra seconds to take aim and disable them (usually you will pass them, so their side and/or rear is visible).

'''''Important Note:''''' Rushing mostly works in cities, where your speed is further increased by paved roads, and enemies will be spaced apart between buildings. In open areas, rushing will usually end up in the IS-4's demise, as opponents will quickly flank you because it's easy to do.

If rushing is not an option, and you find yourself in close-quarters, your best bet is to try to bait shots either for yourself or for your teammates. You can poke your gun barrel out from a corner, and if enemies shoot it, your teammates can drive out and destroy the enemy. Poking out the side of the turret or heavily angled UFP is an option, but most enemies will realize that it's no use shooting there.

'''Realistic Battles'''

In Realistic, the IS-4M retains its ability to rush, although it's subdued. When fully upgraded you can still get up to speed and surprise enemies, especially if you can choose weird routes that are not likely to be checked by enemies. From experience, it's possible to destroy up to 3-4 enemy tanks on city maps like Alaska, American Desert and Middle East, when playing against a good mix of lighter tanks (e.g. Leopard I, Centurion Mk 10, Vickers MBT), as well as some heavier vehicles that can be out-maneuvered.

Armour can protect the IS-4M, but most enemies usually have HEAT loaded, or will be able to load it for the next shot. Most importantly you should never find yourself fighting alone against 3 or more enemies, even 2 are hard to handle most of the time. At least when fighting one-on-one you can always try to retreat or one-shot them, depending on the situation (i.e. either gunner/gun or driver/transmission knocked out).

'''''Important Note:''''' All in all, you should play the IS-4M as if it is a slow medium tank with sub-par firepower due to the reload speed - hope that armour withstands some shots, while taking on enemies one or two at a time; if speed can be gained - use it.

=== The Stock Grind ===
The IS-4M is less painful to play when stock because at times you can get very lucky matches where no-one seems to penetrate you and you get tons of research points for withstanding a lot of shots. Nonetheless, the experience is very much similar to the IS-3 - slow tank, slow reload, gun and engine are often out of commission. Due to this, you must '''research Parts and FPE first''', this is extremely important. Generally, you would want to be behind your teammates, to let them get shot more instead of you, when reloaded you can poke out and shoot your shot, right before going back into the cover or behind teammates. Sniping is an option, but it's not the most viable since there's quite a lot of bullet drop and missing your shots will cause the very long reload.

=== Pros and cons ===


'''Pros:'''

* Very good frontal armour; can even bounce 128 mm shells from the Maus
* Retains the powerful D-25T 122mm gun as on the previous IS-2 and IS-3
* The mere presence of an IS-4 can make enemies panic or run and hide
* Wider choices of ammo compared to the IS-2 and IS-3
* Good reverse speed for a heavy tank
* Can easily one-shot most tanks

'''Cons:'''

* Can - and will - be a priority target for the enemy team due to its fearsome reputation
* Long reload of 25 seconds
* Ammo rack in the back of the turret; if a shell penetrates, the ammo could detonate
* Can be vulnerable to tanks equipped with HEAT and APDSFS
* Armor penetration for the shells can be lacking at the rank
* Small but noticeable weak spot below the gun barrel where the turret meets the hull

== History ==

===Development===
During the development of the [[IS-3]] in 1944 under General Nikolai Dukhov, a separate project was underway by a design team led by L.S. Troyanov to improve the [[IS-2 (1944)|IS-2]] design. This separate project commenced under the designation ''Object 701''. The project produced three proposed design. The ''Object 701-2'' with a S-34 100 mm gun, ''701-5'' with a different armour configuration, and the ''701-6'' with the 122 mm D-25 gun. The ''701-6'' was accepted for further development, to which was modified with thicker armour, longer hull, and a more powerful engine. There was some implementation of German designs into the prototype; the engine has a cooling system that uses a pair of circular fans on the engine deck, a feature also is seen on the [[Panther A|Panther tank]].<ref name="ZalogaIS">Zaloga Steven. ''IS-2 Heavy Tank 1944-73'' Great Britain: Osprey Publishing Ltd., 1994</ref>

===Usage===
''Object 701'' was eventually approved for production in 1947 as the '''IS-4'''. The production turned out 200 tanks (some sources say 250) before the production was halted. The reason being that the IS-4 was criticized for being inadequate in mobility despite its new engine.<ref name="ZalogaIS" /> While production ended, the remaining IS-4 still saw service in the Soviet Union. When the Korean War broke out in 1950 and the United States and its allies got involved, the IS-4s were all shipped to the Far East of the Soviet Union in anticipation of Soviet intervention in the Korean War. They were not committed despite pressure by the Chinese from fear of inciting another world war. Even so, the IS-4 stayed in the region ready for action. In the late 1950s, the IS-4 underwent a modernization program along the lines of the IS-3 with increased ammo stowage, new machine gun armaments, new gun optics, better engine, and better filtration system and this modernized variant was named the '''IS-4M'''.<ref name="ZalogaIS" /> The IS-4 stayed in service in the Soviet Union until the 1960s.

===Legacy===
The IS-4, as a relatively unsuccessful Soviet tank, faded to obscurity with little information on it passed its development period. It was the heaviest of the Soviet heavy tanks that were slated for production. The IS-4's design was further developed on in the IS tank family with the ''Object 703'', with the design using an electrical transmission instead of a mechanical one. This vehicle redesignated the ''[[IS-6]]'', also proved to be problematic and was shelved.<ref name="ZalogaIS" />

=== In-game description ===
Development of this tank began in July 1943 at the ChKZ factory. The main impetus for creating a new Soviet heavy tank was the prospect of being able to install more powerful artillery on it than what was installed on the IS-2. The vehicle underwent testing until the autumn of 1944. The new vehicle had one inarguable virtue - no tank or anti-tank cannon of Soviet or German make could penetrate its 160 mm frontal armour. At the end of 1944, two more vehicles equipped with modernised transmission were produced.

In April 1945, the tank was put into service and mass-produced under the designation IS-4. The vehicle's hull was fully welded, while its turret was cast with tapering armour thickness. Along with its 122 mm D-25T cannon, it was also armed with a coaxial 12.7 mm machine gun. An identical machine gun was placed as an anti-aircraft gun on a ring mount above the loader's hatch. One of the vehicle's characteristic features was its original ammunition rack, in which shells were housed in special metal canisters. The tank had epicyclic transmission and individual torsion-bar suspension. The crew consisted of 4 people. The vehicle's powertrain was a 750 hp B-12 diesel engine. With this engine, the tank could reach 43 km/h on-road.

The IS-4 was mass-produced until 1949. In total, around 250 of them were made. These vehicles served in the Far East.

It became clear during its deployment that the tank's mass exceeded the carrying capacity of most bridges and transport platforms. It was this fact that effectively buried the idea of building vehicles with a mass greater than 50 tonnes. The IS-4 was taken out of operation and placed in long-term storage, and then withdrawn from service entirely. After this, it was often used on ballistic ranges as a target.

E-100

2019-06-08T15:37:03Z

U20374415: Updated pros and cons, added a few things to the strat part, updated gun penetration, tweaked the armour and mobility part.

{{Specs-Card
|code=germ_pzkpfw_e_100
|market=E-100
}}

== Description ==

[[File:GarageImage_E-100.jpg|420px|thumb|left]]
{{break}}
The '''E-100''' is a gift Rank V German heavy tank with a battle rating of 8.0 (AB) and 7.7 (RB/SB). The tank was introduced in [[Update_1.53_"Firestorm"|Update 1.53 "Firestorm"]] and has the distinction of being the second Rank V gift vehicle in-game, with the first being the [[La-174]]. The E-100 could be obtained in the special tournament event, titled "Teutonic Giants" that was held during and after the Thunder League. Only a limited amount of 900 units were given out during the tournament, making the E-100 the rarest tank in-game.

The E-100 looks like a more sleek version of the [[Maus|Maus]], or perhaps a more practical one. The two share the same default camouflage scheme of the yellow ''Dunkelgelb'' and green '''olivgrün'' paint. The two super-heavy tanks also share the same turret design with the 128 mm primary armament along with a coaxial 75 mm and machine gun. The big difference in design though is that the E-100 looks more like a really beefed up Tiger II tank while the Maus looks like a wall.

== General info ==
=== Survivability and armour ===

The E-100 presents a more sloped frontal armour that is more effective than the Maus', the downside in the design is the lower front plate that is thinner, not to mention that it is a big target. The overall design of the tank makes it very resilient against bombs and artillery, to the point of surviving to bombs falling beneath it.

The side armour on the E-100 is also slightly more effective than the Maus. On the Maus, the huge flat side skirts make up part of the side hull armour. On the E-100, the side skirts are completely separated from the main hull and are 75 mm thick sloping, which adds up with the 120 mm flat side hull plate. This feature makes the E-100 able to defeat lesser rounds from low caliber guns. Howerer larger rounds will still be able to penetrate the side skirts with ease, even chemical shells. The skirts can be destroyed after taking enough damage which reveals the very weak side armour of the tank. It should also be noted that shooting between the tracks is a very valid method to take out the E-100 as the armour is extremely weak there.

The rear armour between the two heavy tanks are roughly the same effectiveness, but the E-100 rear slopes inward similar to a Tiger II design while the Maus remains all clunky. However, while the Maus engine is in the center of the vehicle and the transmission is one the back, the E-100 is switched with the engine in the back and transmission in the front, so a penetrating hit to the rear can hit the engine and also set it on fire.

'''Armour type:'''

* Rolled homogeneous armour
* Cast homogeneous armor (Gun mantlet)

|-

'''Notes:'''

* Front hull armour also have 120 mm track guard armor. Not a weak point as these are not in the way of the body.
* Suspension wheels are both 30 mm thick, while tracks are 60 mm thick
* Front part of the belly armour is 85 mm thick, the center and rear part is 40 mm thick
* A 40 mm RHA plate separates the engine compartment from the crew. The engine in general is surrounded by 40 mm plates.
* Rear is protected by engine parts and 60 mm tracks
* Various parts of the engine and rear are covered with 10-20 mm parts.
* Turret ring area on the turret sides and rear has a flatter side than the rest of the turret.

=== Mobility ===

Compared to the Maus, the E-100 truly shines here better than anything else in differences. The E-100 weighs 38 tons less than the Maus and the effect in speed is noticeable, able to go nearly twice as fast as the Maus and is more maneuverable. The tank only reaches his top speed on a downslope, its cruise speed being 24 km/h in a straight line. The reverse speed being half the Maus' makes it average compared to other heavies of that tier. Despite that, the improved mobility gives the E-100 the ability to redeploy on the battlefield and react faster to potential threats.

=== Additional armament ===

{{main|KwK 44 (75 mm)}}

The E-100, like the Maus, also has a coaxial 75 mm with HEAT ammunition for lesser targets so the limited 128 mm shells (42 of them) are not wasted. The 75 mm also can fire smoke round so it is possible to keep a secondary ready with smoke while moving around with an AP round in the main gun.

== Usage in battles ==

The E-100 is played similar to the Maus, with the same armaments and similar armour rating. However, the E-100 has the benefit of increased mobility due to its improved chassis. The E-100 can thus be somewhat more suitable in moving from cover from cover, but close quarter combat is still not recommended due to its still relatively slow movement, long reloads, and the lethal anti-tank armaments the other Rank V vehicles are bound to have, including the now prominent [[Anti-tank guided missiles]]. In a downtier the E-100 can be played much more aggressively and has to put pressure on the enemy team in order to be impactful. The psychological factor makes it easier to achieve this goal as this tank is a very feared foe and can in fact turn the tide of the game. However downtiers should be taken seriously as your enemies will be focused on taking you out. Picking the right targets is also something that an E-100 driver has to master to get good games. When facing a light and an armoured target the main gun should always be used to destroy the strongest tank while the 75 takes care of the squishy one. Even when facing weaker opponents the turret has to be angled between each shot in order to avoid shot traps. When the E-100 gets an uptier you should get to cover as quickly as you can and play it ''extremely'' carefully as any shell may be enough to take you out or at least cripple you. The 128 is not as effective as you now have to aim for weakspots on tanks like the T-55AM-1 and the 75 should become a smoke dispenser.

===Modules===
The usual unlocks should be made. In Tier I, ''Parts'' should be unlocked first to access Tier II, which then should unlock ''FPE'' and the ''PzGr 43'' ammo. Tier III should focus on ''Elevation Mechanism'' and ''Filters''. Tier IV should focus on the ''Engine'' for better mobility. Researching ''Tracks'' quickly makes the E-100 much more enjoyable.

=== Pros and cons ===

'''Pros:'''

* Heavy frontal glacis armor.
* Side skirts may stop low caliber HEAT shells.
* Heavy turret armour against AP-based shells.
* 128mm gun is extremely effective, coaxial 75mm can fire HEAT and smoke shells.
* Lighter and better top speed than the Maus, reverse speed of 10 km/h.
* Boxy shape makes it an easy tank to angle effectively making its armour much better.

'''Cons:'''

* Lower glacis plate is a huge weakspot.
* Armor is not adequate against newer HEATFS and APFSDS shells.
* Large size makes fighting in towns restricting.
* Side skirts won't stop shells from medium to high caliber HEAT shells (>106mm).
* Turret design makes it prone to shot traps.
* Painful cruise speed of 24 km/h in a straight line.
* Long reload makes it important to have a good position.

== History ==

===Development===
Late in World War II, Germany started a project meant to standardize their tank designs. A similar attempt at this started in 1943 with the [[Panther II]], which would use parts from the [[Tiger II (H)|Tiger II]] to simplify construction, but this fell through with the cancellation of the Panther II. The new tank standardization project was known as the ''Entwicklung'' series, or the "E-series", and was meant to fix the issue of poor production quality and increase the production rate. The series was named with "E" followed by the weight classification of the design which would also indicate its role. E-5, for example, would be a vehicle between 5-10 tons and would be the basis of new light tanks. The series followed with the E-10 (tank destroyer), E-25, E-50 (medium tanks), E-75 (heavy tank), and the super-heavy '''E-100'''. Aside from standardization in parts such as the wheel (which was the Tiger II's design), the E-series do not provide much other improvement to existing armor designs, an example is that the E-50 and E-75 series are essentially a redesigned [[Panther A|Panther]] and Tiger II respectively.

===E-100===
Of the designs, the E-100 was the most radical in terms of design. The E-100 was proposed to be the basis of heavy artillery, anti-aircraft, tank, and tank destroyer on the battlefield. The design concept began alongside the [[Maus|super-heavy Maus]] in June 1943 and was intended that the design would use components from the Tiger II and the Maus turret. In March 1944, Adlerwerke submitted the blueprint of the design, which would use the Maus turret and parts from the Tiger II, namely the turning mechanism and transmission. The design proposed the usage of a 700 hp Maybach HL230 used in nearly every German heavy tanks or a newer 1200 hp Maybach engine. Difference in the design from the Tiger II basis was a 90 cm diameter road wheel and spring suspension rather than torsion-bars. The turret was to be a new design different from the Maus, in that it is simpler and lighter.

However ambitious the project was, Hitler ordered in July 1944 that work on the super heavy tanks be cancelled. However, the E-100 was still developed with low priority, only three Adler workers were reported to have been working on the prototype after the order. The prototype was never completed and in April 1945, the American 751st Field Artillery Battalion captured the prototype, of which was simply the hull with the roof barely completed. The prototype was sent to Britain by the British Army for evaluation before being scrapped.
