{{break}}
The '''{{Specs|name}}''' is a rank {{Specs|rank}} Russian heavy tank {{Battle-rating}}. It was introduced during the Closed Beta Test for Ground Forces before [[Update 1.41]].

The IS-2 mod. 1944 was created after the initial disadvantages of the previous [[IS-2]] model (IS-2 mod. 1943), being vulnerable against the 75mm guns of the German StuGs and Panzer IVs due to the nearly flat frontal armour. The Soviet high command then decided to produce another version of the IS-2 with a heavily sloped armour plate, generally known as the IS-2 mod. 1944. It was used successfully on the Eastern front until the end of the war and is remembered as one of the mightiest tanks of World War 2.

In the game, the IS-2 mod. 1944 sits at a BR of 6.3, which is 0.6 higher than the first [[IS-2]]. It now features a mighty frontal plate, sloped at 61° backwards and also a 12.7 mm DShK machine gun on top for AA-defense. It has the same gun as its predecessor, but even at BR 6.3, it is one of the most destructive guns in the game, with high penetration and devastating post-penetration damage.

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

The armour, while having a nigh-impenetrable front plate and a decent turret, has many weak spots.

First, there is the right part of the turret because while on the left side the gun mantlet is connected to the turret armour, there is no mantlet on the right-hand side, so it has just half the thickness of the left side.

Next, we have the lower glacis, which is a very prominent target, with very little armour for its BR (~130mm effective thickness). Shots of a German 88 mm or an American 90 mm will wreak your IS-2 1944.

Last but not least, we have the driver's hatch. While not as prominent as the first two mentioned, many experienced players will go for a shot right here, when you are hull-down. With around 120 mm effective thickness, it is really easy to penetrate even with small guns such as the American 76 mm and has a devastating effect on your tank.

== Usage in battles ==

The IS-2 '44 is a definite improvement on its predecessor, the [[IS-2]]. Most notably the frontal armour now features a slope, which can bounce or outright block some rounds, although the 0.6 Battle Rating increase seems slightly too much. This iteration of the IS-2 also features a roof-mounted machine gun that can be used to attack aircraft without moving your turret (by using weapon selection keys set in the controls). Otherwise, the IS-2 '44 is identical to the IS-2.

=== General Gameplay ===
At Battle Rating 6.3 you will see Tiger II (H) and Panther II a lot, as well as much more heavily armoured vehicles such as the Jagdtiger, the Ferdinand, the T32 and the T95 (in an up-tier). These tanks are near-impossible to penetrate frontally, so you will have to try to flank them. Otherwise, the gameplay remains the same as with the previous IS-2.

Overall, you shouldn't over-extend into enemy territory because your reload is still slow; you should play off of your teammates and use your great reverse speed to get out of line of sight as soon as you shot, or have been shot; you should have fun with the 122 mm gun that blows roofs off of most enemies you penetrate. Flanking is best done in Arcade, while in Realistic you're better of setting up ambushes at a medium distance away from main pathways.

==== Arcade Battles ====
In Arcade, the IS-2 proves to be quite mobile when fully upgraded. This can be used effectively to get into superior positions to engage enemies early in the match when they haven't yet set-up camp in well-covered positions and/or presented their strongest armour. Thus, it's easy to gain a kill at the start of the match, if you are comfortable with the 122 mm gun.

Close quarters combat proves even more deadly in Arcade Battles because all opposing vehicles will be able to easily overrun a single IS-2, especially after it has shot and is now waiting through it's long reload (> the 20s). Hence why it's advised to use your improved reverse speed to quickly disengage after shooting and retreating towards your teammates, who will likely be able to return fire. If the map forces you to fight in close quarters, attempt to get into a position where your teammates can cover your sides, while you can face forwards and clear the road. If the map allows, you can try taking 5 rounds of ammunition and camp at a capture point (usually one that's given to your team) to snipe all enemies that enter your line of sight while reducing your chances of blowing up at the first incoming shot.

In rare cases, it's possible to rush with the IS-2 and surprise lighter vehicles at a contested capture point in the early stages of a game. This strategy relies on the capture point being unpopular and being lucky to face only one enemy vehicle at a time. Some light tanks are unable to penetrate the IS-2 frontally, especially if they are from a much lower rank (e.g. [[BT-7]], the [[Sd.Kfz.234/2|Puma]] or the [[R3 T20 FA-HS|R3]]), so that's an added benefit of being a decently mobile heavy tank. If successful, the IS-2 can then flank to other objectives or advance to the enemy spawn to destroy another enemy or two. You shouldn't expect a lot of easy targets with this strategy, because it exposes your tank to potentially a lot of enemy fire.

==== Realistic Battles ====
In Realistic, the IS-2 begins to feel like a heavy tank. Its mobility is heavily reduced and its speed is outmatched by practically everything, mostly due to poor acceleration off-roads. However, this should be used as an advantage to gauge where the enemies are set-up, by looking where your teammates are killed from. You can then decide to return fire, although sometimes opponents don't show themselves until later in the match, in which case you should stay passive and try to remain behind your team's front lines.

Due to generally increased map size in Realistic, you will have to get comfortable with the bullet drop. There is an added benefit to that because the following [[IS-3]] and [[IS-4M]] mount the same gun (as does [[T-44-122]] and [[KV-122]], if you have them), and [[T-10M]] has similar bullet drop. Now, the IS-2 performs decently well at longer ranges, but it will cost you a lot if you miss or don't penetrate, because the reload is so long. Often, you will need to rely on the rangefinder, the teammates or map knowledge to gauge how high you need to shoot, so it might be a great idea to take out another vehicle first (such as the [[T-44]] or [[T-34-85]]) remember the distance and then take the IS-2 out. However, on larger maps, it is generally a better idea to take out other vehicles.

A more reliable strategy for the IS-2 is to camp nearby an objective and pick off any enemies who pose a threat. Just make sure to find a flat spot with cover, because your poor gun depression and long reload will be your death in hilly or open areas. It's also a good idea to target heavy enemies, because they are easier to hit, and also will likely pose a larger threat to your general team (e.g the [[Ferdinand]], the [[Ho-Ri Production|Ho-Ri]] or the [[Tiger II (H)]] ).

====General Tactics====

Although classified as a heavy tank and an upgraded improved design over the KV predecessor, the IS-2's armour will no longer hold up to its more common and heavier opponents of its Battle-Rating and Rank. Compared with other vehicles such as the new German Tiger II, American heavy T-series tanks; most of which can easily deflect even the most powerful shots of the IS-2 unless targeted specifically and known weak-spots. Because of this, it is recommended to always travel and fight in groups of two or more vehicles. The slow and difficult in the manoeuvring of the vehicle (especially in confined spaces) will more than once place the IS-2 in significant danger. It is recommended to field the IS-2 into a fire-support role, peeking over the shoulder of friendly, more heavier vehicles and firing a shot against the opposition in tandem.

Another significant note of this vehicle is the IS-2's considerably fast reverse rate, the highest of its Rank and Battle-Rating for the nation's faction inherited from its IS-1 predecessor, topping at 17 km/h. During situations where engagement is expected, an unorthodox strategy can be utilized where the operator of the IS-2 tank re-positions the vehicle 90 degrees and drive in reverse with the rear-facing towards the enemy. By driving in reverse this way, the engine blocks make a crude yet somewhat effective shield to protect the more delicate crew members. As the fuel tanks are mostly stored at the front on the left and right side of the driver's station, the risk of fire and fuel-tank explosion is reduced significantly (but not completely eliminated) and thus, the tank is able to resist even the most powerful of shots. Be aware that more experienced players may attempt to instead fire at the more exposed turret of the IS tank and instantly knocking out the crew with a common APHE penetrating shell in this way.

In regards to shells, the D-25T cannon is also equipped with powerful High Explosive (HE) Shells which should not go ignored. Firing a HE shell with precise aim directly underneath the chassis of enemy vehicles were the armour, like on the top of the vehicle if thinnest, can cripple or instantly destroy said enemy vehicles. In rare instances, the HE shell of the D-25T is so powerful to the point two or more medium or heavy tanks close to each other can be destroyed with a single exploding HE Shell.<ref>https://www.youtube.com/watch?v=orjvoBexPd4</ref> Alternatively, the powerful armour-piercing capability of the D-25T cannon's APHE rounds has also been documented to pierce two or three light-armoured targets without exploding, claiming hull-break wins. <ref>https://www.youtube.com/watch?v=EpXjG9ORxTI</ref>

=== Moving from IS-2 to IS-2 (1944) ===
This section will go into more detail about the differences between fighting with this machine, the challenge is that some of the enemies which can be faced are simply impenetrable frontally. You will have to either have to run or outflank them! However, it is critically important to watch your flanks, due to the other enemies which will also be facing, trying to outflank you and hit you in your sides!
because of the saturation of good and highly mobile vehicles that other nations have at this Battle Rating such as: [[Ru_251]], [[Panther_(Disambiguation)| Panther tanks]], [[Tiger_II_(H)|Tiger II (H)]], [[Caernarvon]], [[T34]], [[AMX_M4|AMX M4]] and many more.

==== Specific Enemies Worth Noting ====
These are new (or common) vehicles you will see in this tank. Read the specific enemies section in the IS-2 article to get a full run-down.

* ☠ T32 - You have to go for the MG port in the lower left of the UFP, otherwise you can only penetrate the side armour or the rear.
* ☠ T28 - You can only penetrate the cupolas on top of the tank. If they're hidden or you are unsure about the shot, you can try hitting the cannon barrel and running away.
* ☠ Ferdinand - Go for the angled armour at the sides of the lower front plate (below the casemate, but above the lowest plates), this will disable Ferdinand's engine and/or driver, so you can flank and finish it off.
* ☠ Jagdtiger - You cannot reliably penetrate or damage this tank frontally. You can try disabling the cannon barrel, and then flanking is your best option (or running away).
* ☠ Conqueror - Shoot the hull, don't shoot the turret.
* ☠ Ho-Ri Production - You cannot reliably penetrate or damage this tank frontally. You can try disabling the cannon barrel and then flanking is your best option (or running).
* ☠ AMX-50 Foch - You cannot reliably penetrate or damage this tank frontally. You can try disabling the cannon barrel and then flanking is your best option (or running).
* T34 / T29 - Turret cheeks can work, although it's best to go for the LFP because the ammo storage is very low in the tank. If you don't see the LFP, try going just below the turret ring, where the driver sits.
* Tiger II (H) / Panther II - You can easily penetrate the turret cheeks with BR-471B.
* Panther D, A, G, F - You can penetrate the UFP 
* Tortoise - Shoot to the right of the gun of the Tortoise, when you see it head-on if shoot on the left plate there is a chance of a one-shot
* AMX-50 Surbaissé - Go for the LFP.

=== The Stock Grind ===
When grinding the first modifications, Arcade Battles might be more fun, because of faster-paced gameplay and the ability to see all threats. Now, it's '''a priority to research Parts and FPE''' (you may want to activate 3-5 universal vehicle back-ups to be able to respawn twice in one match if you really wish to upgrade this vehicle quickly).

General stock grind advice:

* Don't show your rear to any enemies, because a single fire will be your death.
* Your gun is still very effective, so don't be afraid to attack enemies frontally, just make sure to aim for weak-spots if possible.
** Shooting at planes in Arcade with your machine gun (or main gun) and scoring some hits can often award you a kill if the plane crashes, which grants points.
* Play as a support tank - push with your team and let them take fire, then poke out and take your shots, then retreat back into cover.
** Try to push into objectives with your team to gain those points as well.

=== Pros and cons ===


'''Pros:'''

* Great 122 mm D-25T gun, featuring good penetration and devastating post-penetration damage.
* Extremely strong upper glacis, with about 230 mm effective thickness, sloped at 61°
* Superb reverse speed (18 kph)
* Decently mobile for a tank of its size
* 12.7 mm machine gun on top against planes
* Decent turret armour on the left side
* Angled armour can bounce some unexpected shells
* Playing the tank while stock isn't bad

'''Cons:'''

* Long reload for its main gun (27 seconds without crew skills)
* Many weak spots (Driver's hatch, lower glacis, the right side of the turret)
* Only four crew members
* Worse optics than its predecessor
* Can't side scrape, due to its cheeks
* Ammo capacity for the MG on top is low, only 250 rounds

== History ==

===Development===
The effort began on another heavy tank after the [[IS-1]]'s 85 mm gun no longer had a firepower advantage after the standard [[T-34 (1942)|T-34]] medium tank was upgraded with the same gun into the [[T-34-85]]. Due to that, the IS-1 was discontinued in January 1944 with about 107 units produced.<ref name="ISZaloga">Zaloga, Steven J. ''IS-2 Heavy Tank 1944-73'' Great Britain: Osprey Publishing Ltd., 1994</ref> Those in storage still awaited upgrade to become a more powerful heavy tank.

In late 1943, the upgrade of the IS tank began and the choices available were rounded down to two weapons, the 122 mm A-19 gun and the 100 mm D-10 gun. Both guns had their advantages and disadvantages in their specifications, the 100 mm D-10 had a much better armour penetration capabilities and uses a single-piece ammunition, the 122 mm A-19 has a better high-explosive round and used a two-piece ammunition In the end, the 122 mm A-19 (adopted as the D-25T) gun was chosen as the gun of the new IS tank due to larger supply of the gun available for use (the D-10 was a newly produced gun) and the better high-explosive round available. The better high-explosive round is due to the heavy tank's specification as a "breakthrough" tank than an anti-tank role, so it was meant to fight fortifications more than against armour. Nevertheless, against armour, the 122 mm gun proved a very lethal cannon against armour, having the capacity to knock out any German tanks fielded in the war, even the [[Tiger II (H)|Tiger II]], though the ease of knocking them out vary from their armour protection.

The 122 mm gun's two-piece ammunition was perhaps the gun's worst drawback, this along with the heavy shells and charges that it uses causes reloading speed to only be one and a half rounds per minute maximum. Even after some modernization to the gun including a semi-automatic breech, the firing rate only increased to two to three rounds per minute. Another drawback of the gun was the size of the ammunition that the 122 mm gun uses, the IS tank interior could only hold 28 of such ammunition, which restricts the time the IS could last in battle before requiring a resupply. In battle, the usual distribution of the shells is 20 high-explosive and 8 armour-piercing rounds.

The finished IS tank with the 122 mm gun, first called the ''IS-122'', was finally approved and renamed the '''IS-2''' heavy tank, some were rearmed IS-1s from the factory with the 122 mm gun. The IS-2 tank, like the IS-1, was superior to the previous [[KV-1 (ZiS-5)|KV-1]] tanks used in the Red Army. Production of the IS-2 started in October or November 1943 and by the end of World War II when production ended, a total of 3,854 units were produced.

===Design===
The IS-2 tank hull was similar to the IS-1 tank, but the turret was modified to accommodate the larger 122 mm D-25T gun. The suspension was a torsion-bar suspension system and the tank was powered by a diesel V2-IC engine. The drivetrain and the engine were taken from the KV-1 tank, yet was considerably more mobile. The armour on the IS-2 was a 120 mm thick front plate sloped at 60 degrees with a small step in the front for the driver's hatch. This [[IS-2|"early version"]], developed from the KV-13 design, was produced from the initial production lines until some time in late 1944, where a '''[[IS-2 (1944)|IS-2 mod. 1944]]''' version was modified with the front plate now a single sloped 120 mm plate at 60 degrees with no interruptions in order to eliminate shot traps and weaknesses in the armour design. Other design changes when the IS-2 was upgraded to the 1944 model was a stronger gun mount, wider mantlet, and an addition of a Dshk machine gun on the turret. The formidable armour of the IS-2 is able to withstand the 88 mm shells from the [[Tiger H1|Tiger I]] at 1,000 meters out, yet the whole tank weighs less than the Panther at only 46 tons. Despite its construction, the IS-2 was still quite crude in quality and can have signs of being hastily built from the factories. This did not affect its battlefield performance greatly and the crude construction is merely a side effect of the fast production of the tanks to fill battlefield demands.

===Combat usage===
The IS-2 first saw action in early 1944. The IS-2 was organized in heavy tank regiments, each with 21 tanks. Their role was to spearhead the offensives launched at each sector, breaking through enemy emplacements and supporting the infantry by destroying enemy fortifications, they were not meant to exploit breakthroughs and this role was given to the lighter [[T-34-85|T-34]] tanks. Their first reported action was in April 1944 in the 11th Special Guards Heavy Tank Regiment near Tarnopol, Ukraine. The IS-2 presented such a surprise to the Germans as no Soviet tanks before could engage with accurate fire from more than 3 kilometres away. A bigger shock was when they found out the 88 mm of the Tiger I couldn't adequately penetrate their armour. The IS-2 initial combat experience was limited due to the inexperienced crew and organization, but more and more IS-2 started to come in to reinforce the Soviet forces.<ref name="ISZaloga">Zaloga, Steven J. ''IS-2 Heavy Tank 1944-73'' Great Britain: Osprey Publishing Ltd., 1994</ref>

The IS-2's next great effort was in Operation Bagration in July 1944. By this time period, the heavy tank regiments were allocated to one for each tank corps. During Operation Bagration, the IS-2 combat effort contributed to the decimation of the German Army Group Center. The IS-2 was able to deal with the troublesome German Panther and Tiger I tanks with ease. By December 1944, enough IS-2 was produced that the Soviets began outfitting them to Guards heavy tank brigades, consisting of 65 IS-2 tanks with other vehicles for support. Though the number of these brigades were still limited, they proved valuable in breaking through German lines, as used in January 1945 against the German in the Oder Offensive. It should be noted that despite having a role similar to the Tiger heavy tank battalions in the German service, they are produced in far greater numbers to enforce every tank corp with one heavy tank regiment that allowed even the IS-2 to overwhelm German defences. The IS-2 continued to see combat service for the Red Army all the way to the Battle of Berlin and the end of World War II.<ref name="ISZaloga">Zaloga, Steven J. ''IS-2 Heavy Tank 1944-73'' Great Britain: Osprey Publishing Ltd., 1994</ref>

Still, the IS-2 was far from perfect. Even with a strategic advantage, the Soviet army lost a considerable amount of IS-2s, mainly as a result of superior German engagement tactics; the long reload rate also gave the tank a significant drawback. The German tank crewmen, now familiar with their new enemy, found that they still feared the Tiger and retreated as soon as the Tigers engaged. This fear would be amplified with the introduction of the Tiger II; when such a tank was sighted, many Soviet tank commanders resorted to abandoning their vehicle. These circumstances prompted Soviet commanders and officers to improve their strategies of countering enemy tanks.

After World War II, the IS-2 production was replaced by the more heavily armoured [[IS-3]]; however, the IS-2 stayed in service up until 1982 due to modernization efforts on the IS-2. This modernized IS-2 was named the ''IS-2M'' and was done in the mid-1950s. These modernization efforts added external fuel tanks and stowage bins onto the hull and protective skirts on the edges of the tracks. The IS-2s were finally placed into storage in the 1990s and were kept in reserves or sold out as scrap metal.

Like most of Soviet Union's military hardware, the IS-2 was given out to the Warsaw Pact nations as supplies. The IS-2 was thus lent out to Poland, Czechoslovakia, Hungary, China, North Vietnam, and maybe North Korea. Later in 1960, a shipment of IS-2 was also sent to Cuba, which were converted into bunkers and coastal defences as spare parts for the tank never made it to Cuba due to the US blockade imposed in 1962.

=== In-game description ===
In 1944, the IS-2 was modernised. The new model had a flattened sloping frontal hull, and a slot covered with a glass brick was installed to replace the driver's observation hatch. This increased the front hull projection's defences. A high-calibre 12.7 mm anti-aircraft DShK machine gun was attached on a trunnion fixed to the command cupola's traverse circle.
The turret could be rotated mechanically and electrically. With electric drive activated, its maximum speed reached 2.4 revs/min.

The IS-2 was advantageous for its economy and relatively low material requirements in general. With a mass of 46 t, the Soviet tank was far better protected than the German Panther. It also surpassed the 55 tonne Tiger I in this regard and was only somewhat inferior to the 68 tonne Tiger II. Its design had some serious flaws. Its tight layout meant that some of the fuel tanks had to be placed in the fighting compartment and there was no space for a driver's hatch, which often led to an injured tanker being unable to quickly leave a burning tank.
On the whole, the new tank met the leadership's expectations in full as a means of strengthening units and divisions intended to break through the enemy's pre-emptively well reinforced defensive lines and storm cities.

IS-2 tanks were put into service in separate tank regiments which received the "guards" designation during their formation.
Manufacturing continued until 1946, and around 3,300 were made.
After the war, the IS-2 was modernised and served in the Soviet and Russian armies until 1995.
A small number of tanks of this model were given to China in the 50s. Later, some of these tanks were deployed in Vietnam.

== Description ==

[[File:GarageImage_TigerH1.jpg|420px|thumb|left]]
{{break}}
The '''{{Specs|name}}''', also known as the '''Tiger H1''', is a rank {{Specs|rank}} German heavy tank {{Battle-rating}}. It was introduced during the Closed Beta Test for Ground Forces before Update 1.41. The Tiger I carries its reputation from real-life to its in-game performances, armed with the infamous [[KwK 36 (88 mm)|88 mm gun]] that can easily destroy most tanks it meets. The armour of the Tiger I is formidable at 102 mm and can be easily sloped by tilting the tank approximately 45° to the side, with the side armour thick enough for glancing side fire as well. Mobility is also decent for a heavy tank due to its 650 hp engine and suspension, making the Tiger I a near jack-of-all-trades at its level.

The Tiger H1 is an early production variant of the Tiger I tanks. However, it is the basis of the Tiger I tanks with the three features: the long 88 mm KwK 36 gun, the ''Schachtellaufwerk'' interleaving torsion suspension system, and a box armour shape of the hull with a circular turret housing the 88 mm gun. The tank is painted in a flat ''Dunkelgelb'' yellow coat, though there are large swatches bare metal from scratched off paint.

The Tiger H1 tank is most distinctive from its later production models is its drum-shaped, cylindrical cupola protruding from the top left of the turret. Turret-mounted smoke dischargers known as the ''Wurfbecher'' are mounted to the turret sides slightly behind the gun mantlet. On the hull-roof, there are also five S-Mine dischargers, with three on the left side and two on the right side. On the hull rear, there are two ''Feifel'' air cleaner units that were intended for dusty environments.

'''Notes:'''

* Turret front covered by gun mantlet has variable thickness depending on exact place, ranging from 90 to 200 mm of armour.
* Turret side (about 1/3) is covered by attached tracks, adding additional 30 mm of armour.
* While the hull side of the tank is 82 mm, the side where the suspension is located is only 62 mm thick so be aware of this weak point.
* On paper, the best angle is roughly 38.8° with armour all-round being from the front 130 mm.

One may feel the need to charge head-on into battle, blaring that 88 mm gun as shells bounce off the front armour while the ''Schachtellaufwerk'' suspension system runs over the ground; this is a short-lived strategy.

The Tiger I should be played more like a bulky medium tank rather than a heavy tank despite its status, supporting allies from the sideline or from a distance rather than leading directly from the front. This is due to the poor armour arrangement with its "boxy" features, providing no sloping benefits alone. One must remain a distance, exploit the 88 mm long-distance power, and maintain a diamond-shape compound angling to maximize armour thickness against the trailing enemy shells that will inevitably come towards the Tiger's way.

* '''PzGr 39''' The go-to shell for all Tiger H1 drivers as this is arguably the best. It will do incredible damage to any tank shot by it, except SPAA, or any extremely thin armoured vehicles. Heavier tanks like the IS-1, IS-2, or American heavy tanks are able to resist the round at longer ranges, but well-placed shots from close range or sides will do the job. All other medium and light tanks will be history as soon as this shell make contact with them. This shell, however, will almost always over-penetrate all but the most armoured SPAA vehicles, so it is best to use HE or machine gun fire on thin-skinned vehicles.
* '''PzGr ''' This shell is also very useful. It has very similar characteristics as PzGr 39, but sacrifices some penetration for about 50% more Explosive Filler, meaning even more damage than already powerful PzGr 39. It is recommended to carry some of these shells and use them regularly, as the penetration is still enough to deal with most targets (at least when being down-tiered), and switch to PzGr 39 when shooting targets far away, or those that are heavily armoured.
* '''Sprgr. 39''' The HE shell is completely ineffective against all but SPAA or the AI artillery on the Kursk and Ash River maps, and the machine gun mounted on the Tiger has proven quite capable of dealing with these. Keep a small supply of this shell on hand if planning to flank the enemy and take out their SPAA or artillery, but avoid them for everything else.
* '''Hl.Gr. 39''' On paper the HEAT rounds don't bring anything new to the table, however they can be used as a substitute for the HE shells due to the greater explosive mass and still gives a fighting chance if caught with pants down.

== Usage in the battles ==

The main role of the ''Tiger'' tank was to eliminate enemy tanks at a far range, similar to behaving like a sniping tank, or a Tank Destroyer. Nonetheless, the Tiger can excel at brawling with other tanks at medium, even possibly against two [[Panther D|Panther]] tanks to close range and escape undamaged. It's recommended to not stay in one place for too long or risk getting outflanked, spotted, or bombed.

While guns like the Soviet [[D-5T (85 mm)|85 mm]] cannon can easily penetrate the Tiger at close range, the Tiger can stay nearly invulnerable at long range. The 88 can take out any tank on Rank 3 at any combat range but may have problems with the [[IS-1]]'s 120 mm front amour at some ranges. When having to close in a bit, it is generally advisable to angle the hull to the sides by about 30°, improving the armour rating enough that it can keep away 85mm shells very well, even at closer ranges. The Tiger is still vulnerable to the [[SU-152|SU-152s]] howitzer and its HE shell at any range. So whenever encountering these heavy-calibre vehicles, it should be prioritized and eliminated first.

'''Mobility'''-wise the Tiger is pretty good for a heavy tank. It is much faster than a [[KV-1 (ZiS-5)|KV-1]] and about as equally fast as the [[IS-1]], although medium tanks like the [[T-34-85]] can easily outmanoeuvre all three at close range. Try to use the Tiger's mobility to keep a distance rather than for closing in on a target. Don't be afraid to use the speed to fall back if necessary as the Tiger cannot survive close range engagements on open terrain vs. mediums, due to the slow turret and the vulnerability to the 85mm guns on Soviet medium tanks.

The Tiger has a very bad '''turret traverse''', it is recommended to get the ''Turret Drive'' traverse modification as fast as possible. Even then, the Tiger will have to turn the tank in the direction of the traverse to make the most of the time to quickly engage a target. This, together with very exposed ammo racks on both sides (though one side can be emptied by reducing the ammo stowage) means that facing multiple enemies at once is almost a certain end to the Tiger tank. The best option is to take cover from one tank and fire on the other.

As far as ammo is concerned, the default ''PzGr 39'' will be the standard AP rounds many players will use. The second AP round available, the ''Pzgr.'', is also a good round to use against the enemy as the shell contains more explosive filler than the default, but suffers from a lower penetration value compared to the ''PzGr 39''. The HEAT rounds only offer more penetration at extreme ranges (>2000m) and do less damage upon penetration, so it should just be omitted from the Tiger's combat load. Upgrading the tank should mainly be dedicated to turret traverse, hull traverse (as this is needed even with the turret traverse upgrade) and engine upgrades. The Tiger's 88 has massive destructive power. Unlike the other German tank of its rank, all armed with 75 mm guns, the Tiger can easily one-shot all the mediums like the T-34s, M4 Shermans, and still be a threat against heavy tanks like the IS-1s. If it doesn't destroy a tank in one hit, most of the enemy crew will be wounded or incapacitated. The best place to aim with the 88 is either at the gunner's side of the enemy turret to incapacitate an enemy's firepower, or between the driver and the gunner which would usually wound or knock out most of the enemy crew at once. Attacking from the side also presents a good shot opportunity, as the best shot placement is right below the turret on the hull where most of the tank ammunition are stored, giving a big chance for an ammo-rack explosion.

When driving the Tiger, plan ahead on where it will drive. Even with engine and track modifications, the Tiger is still a heavy tank and a 90 degree or more turn will almost always mean an immediate standstill as the tank try to make the change in movement. Even small adjustments can knock the speed down a bit. Thus, knowing the terrain and destination is of the utmost importance to preserve its mobility to its fullest extent.

The Tiger is also best used on the flanks of the current maps, as these are usually more open and allow good use of its armour and excellent gun. The centre of the map would seem more logical as there are a lot of enemies, but as has already been established a Tiger taking fire from multiple directions won't last long. Going in a flank and taking down light and medium tanks is an easy task for this beast, and thus a flank can be easily secured if the Tiger is driven carefully. Then, work the Tiger into the enemy sides and rear of the main force in the centre, doing much more damage than if the Tiger faced the force head-on because a shot to the side and rear will set most enemies alight if not outright exploding the ammunition. Able to destroy vehicles in one hit, the Tiger can quickly jump from target to target and eliminate a good number of enemies in its lifespan.

There will be many hard eggs to crack such as the IS- Series, T-34 Series, American Jumbos, and several other tanks that will give the Tiger I trouble.

* The Russians have many tanks at the BR able to handle the Tiger H1 easily. The main tank at this BR is the T-34-85's. While it may have very thin armour and is easy to penetrate it is easy to angle and the T-34 is a franking machine, it will drive circles around the Tiger so it needs to be destroyed quick. The IS- Heavy tanks are the second worst nightmare situation. Thick armour and a huge gun. If the IS tank is not destroyed first, it will definitely destroy the Tiger.
* The American Jumbos are similar to the T-34. The 75 mm variant would have trouble to penetrate the Tiger's armour at long ranges, but caution needs to be exercised when they are armed with a 76 mm gun.
* The Japanese tanks all have very thin armour that the 88 mm gun can easily penetrate through with no problem, but their guns at this BR all have enough penetration to deal with the Tiger if it gets a hit on.

===Modules===
For Tier I modifications obtained the vital ''Parts'' and ''Horizontal Drive'' modifications as the former will give the Tiger the ability to repair and the latter will provide a much-needed boost to the Tiger's slow turret traverse rate.

=== Pros and cons ===

'''Pros:'''

* Turret armour is particularly hard to penetrate, especially around the mantlet
* One of the fastest heavy tanks with its top speed of 45 km/h
* Good reverse speed
* It's box-like shape gives the ability to some angling tactics
* The rear is surprisingly hard to penetrate, partially due to the slightly-angled armour and partly due to the large exhaust pipes which seem to deflect shells

'''Cons:'''

* Has trouble dealing with other heavy tanks
* Only performs well against soft targets
* Lower Glacis is easy to penetrate, therefore watch for one going over hills
* Transmission catches fire easily if struck
* Ammo racks offer great targets
* Slow acceleration and turning speed
* Turret traverse is second slowest on heavy tank line for Germany
* Low manoeuvrability, susceptible to being outflanked by more quicker adversaries
* Unsloped armour on all sides
* Armor is worthless unless angled
* Can meet against some tough opponents
* S-Mine dischargers on the hull limits gun depression in certain areas

== History ==

===Development===
The '''Tiger I''' heavy tank was arguably the most infamous tank of World War II. The design for this tank began as early as January 1937 when Henschel & Sohn worked on a large "breakthrough" called the ''Durchbruchwagen'' that weighed about 30 tons on request by the German military.<ref name="ImagesOfWarTiger">Anthony Tucker-Jones. ''Images Of War Special: Tiger I & Tiger II'' Great Britain: Pen & Sword Military, 2013</ref> The request was modified over time for more armour and better gun that increased the weight to 36 tons, but this project was dropped in 1938 in favour of the better prototypes VK 30.01(H) and VK 36.01(H). These new prototypes were the start of the usage of the ''Schachtellaufwerk'' wheel arrangements, but these also never passed prototype stages and were both cancelled in 1942.

During the development of the prototypes above, the German invasion of France showed that the Allied tanks such as the Somua, Char B1, and [[Matilda Mk II|Matilda II]] were impervious to their current anti-tank weaponry and a need for better armoured and armed tanks was emphasized. So on May 26, 1941, Henschel and Porsche were asked to submit designs for a 45-ton heavy tank that was to be ready for demonstration by June 1942. During their development in June 1941, Germany initiated Operation Barbarossa against the Soviet Union and was shocked by appearance of the [[T-34 (1941)|T-34]] and [[KV-1 (ZiS-5)|KV-1]] tanks that were invulnerable to all but the most potent anti-tank weapon in German inventory, one of which was the [[KwK 36 (88 mm)|88 mm FlaK cannon]]. The potency of the 88 mm cannon against the heavily armoured tanks that the Germans faced had Hitler ordered that the heavy tank design undertaken by Henschel and Porsche to utilize the 88 mm as its main armament instead of a 75 mm cannon.

The designs of the tank were finalized and ready for demonstration on April 20, 1942, Hitler's birthday, and showed the ''VK 45.01(H)'' and the [[VK 45.01 (P)|VK 45.01(P)]]. The demonstration and subsequent evaluations on the two designs determined that the Henschel variant was superior to the Porsche variant, proving more reliable, more mobile, and more easily produced than the Porsche. This caused the Henschel variant to be adopted as the '''Panzerkampfwagen VI Tiger''' and production started in August 1942. The Porsche variant had many chassis produced as Ferdinand Porsche thought the design would win, so the chassis was instead used in the [[Ferdinand|Ferdinand]] tank destroyer.

===Design===
What perhaps made the Tiger I so unique in tank development and German doctrine is a change of focus between the three characteristics of the tank; with more emphasis to firepower and armour than to mobility. The Tiger I contained the large [[KwK 36 (88 mm)|88 mm KwK 36 cannon]] which was very accurate and powerful, being able to penetrate every Allied armour present at its introduction. The armour on the Tiger I was also one of the greatest at the time, with an astounding 102 mm of armour on the front hull armour, 82 mm on the side superstructure and rear, and 120 mm on the gun mantlet. The armour was vertical faced so no sloping benefits were present like on the [[Panther D|Panther]]. All these armour thicknesses proved invulnerable to most Allied anti-tank weaponry at the time, requiring more creative methods in a shot placement to disable the tank. The mobility, while taken with less emphasis in the development, was still respectable at the time as the tank weighed about 57 metric tons, about 20 tons more than other country's main tanks, yet is able to keep up a speed of 38 km/h (Maximum speed was 45 km/h, but an engine governor was installed to preserve the engine life).

The tank utilized a torsion-bar suspension system in a ''Schachtellaufwerk'' overlapping pattern, making the Tiger one of the first German tank design to use the pattern. While the design gave the Tiger I great flotation due to the use of a wider track for lower ground pressure, it had disadvantages in environment and maintenance. In the Eastern Front, mud and other foreign objects could be jammed in between the overlapping wheels, which would freeze in the winter and jam the wheels; the overlapping wheels also were a hassle to change out, in order to replace one wheel in the inside of the suspension, it requires the removal of at least nine other wheels in order to access it. The first 250 Tiger tanks used a Maybach V-12 HL210 engine with 650 hp before switching over to the more powerful Maybach V-12 HL230 engine with 700 hp. The engine proved adequate in propelling the tank but was still considered underpowered for the tank weight.

The Tiger I, as innovative as it is to tank warfare, was a strain on German war production. The tank was over-engineered, taking much more man-hour and materials for its worth as a war machine. Cost-wise, two [[Pz.IV G|Panzer IVs]] or four [[StuG III G|StuG IIIs]] can be built for the cost of one Tiger I. The tank was also expensive to maintain and took lots of fuel to run. These attributed to the low number of only 1,354 Tiger Is produced from 1942 to August 1944.<ref name="ImagesOfWarTiger">Anthony Tucker-Jones. ''Images Of War Special: Tiger I & Tiger II'' Great Britain: Pen & Sword Military, 2013</ref>

===Variants===
There are three main production Tiger I variants known today, the "early-production", "mid-production", and "late-production" models. The ''Early-production'' model, designated as the '''Panzerkampfwagen VI Ausf. H''', were the first few batches and are distinguished by their drum-style cupola with an over-swinging hatch. The model also had two vehicle lights on the front side of the tank and dished steel wheels with rubber tyres. The ''Mid-production'' featured ''Zimmerit'' paste and a side-swinging cupola with accommodation for a machine gun mounted on the cupola. The vehicle light was also changed to just one placed right in the front of the hull armour. The mid-production was also redesignated in May 1943 as the '''[[Tiger E|Panzerkampfwagen VI Ausf. E]]'''. ''Late-production'' models featured the removal of the ''Zimmerit'' paste as there was an assumed flaw with it, and the overlapping wheels were instead made into interleaving with full-steel road wheels as well, in a manner similar to the [[Tiger II (H)|Tiger II]].

Other specialized variants of the Tiger I was produced as well. A small number of demolition carrier models were field-made in Italy, where it had its main gun replaced by a crane to carry demolition to clear minefields or destroy obstacles. The demolition carrier version was interpreted by Allied intelligence as a ''BergeTiger'', an armoured recovery vehicle, though it is not known if it ever saw service in this role. Another specialized variant produced in 1944 in some numbers was the ''Sturmtiger'', an heavy assault gun with a 38 cm rocket launcher made from a depth charge. 19 of these were made and saw use in all fronts, though its most noteworthy combat action was in the Warsaw Uprising.

===Combat usage===
In its introduction, Hitler ordered the new Tigers to be used in the Leningrad siege in September 1942. However, as the faults of the tank were still not yet fully ironed out at this stage, the mechanical unreliability and the unsuitable terrain caused one of the Tiger Is to be stuck in the swamps and abandoned by its users. This example was then captured by the Red Army and tipped off the Allies of the development of the new Tiger tanks and so developments in countermeasures began. In North Africa, the Tigers saw the first action against the Western Allies in Tunisia in December 1942. Its impact there left an impression on the Allied armour forces, but its myth as an invulnerable tank was shattered when two Tigers were taken out by the British [[Ordnance QF 6-pounder Mk.III (57 mm)|6-pounder anti-tank guns]]. The total loss in that campaign was seven Tigers by February 1943.

Once mass-numbers of Tiger Is were available, they were employed in heavy tank battalions that were to be deployed in breakthrough operations or counter-attacks. Field experience with the Tiger showed that the Tiger's heavyweight proved a nuisance in operational mobility, an example being that small bridges were unable to support the Tiger tank's weight. An attempt to remedy this was to use a snorkel device so the tank could ford rivers as deep as four meters, however, this system was phased out of later production models for cost-savings. The Tiger suffered reliability problems in all of its service life that impeded its effectiveness and its high fuel usage limited its combat operations. Armour recovery of the vehicle was also terrible as three heavy recovery half-tracks were required to tow the tank away, causing a strain on the German support line to keep the Tiger tanks in running order. Despite that, the Tiger I proved superior in terms of armour and armament against the Allies and created massive losses among their armoured forces, causing many soldiers to keep an eye out for the infamous "Tigers".

The impact the Tiger had on the battlefield as the superior tank at its introduction created fame to the commanders and crew operating this tank, further fueling the Tiger's reputation in the war as a killing machine. Some Tiger units were able to achieve kill ratios up to 10:1, and some even higher. Some notable Tiger aces known were Kurt Knispel (168 tank kills), Otto Carius (150+), Johannes Bölter (139+), and Michael Wittmann (138).

However, as the war progressed and the impact of the Tiger's surprise in Kursk and Italy has dissolved, Allied developments gave forth more capable tanks able to defeat the Tiger I tanks. The Soviets solution was to up-gun their [[T-34 (1942)|T-34s]] with an [[D-5T (85 mm)|85 mm gun]] to make the [[T-34-85]], and the Western Allies with the [[M1 (76 mm)|76 mm]] and [[Ordnance QF 17-pounder (76 mm)|17-pounders]] on the [[M4A1 (76) W|M4 Sherman]] and [[Sherman Firefly|Firefly]] respectively.. The Tiger went as an highly-invulnerable tank design into a simple heavy tank as the war went on, and it was replaced by the more powerful and more heavily armoured [[Tiger II (H)|Tiger II]] in 1944. Despite its replacement, many Tiger I models still saw use up until the end of World War II.

===Survivors===
Due to the low number of Tiger Is created during the war (1,354, compared to [[Pz.IV H|Panzer IV]]'s 8,550 and the [[M4|M4 Sherman]]'s ~50,000), very few intact Tiger I pieces are left in the world. Today, only seven tanks in various conditions are existent in the world. The most famous of these is the ''Tiger 131'', captured by the British in Tunisia in April 1943, when the crew abandoned the tank due to a [[Ordnance QF 6-pounder Mk.III (57 mm)|6-pounder]] shot from a [[Churchill Mk III|Churchill tank]] jamming the gun mantlet and turret ring, causing it to be unable to aim. The intact sample is also famous for being the only fully operational Tiger I in the world due to a reconstruction effort by the Bovington Tank Museum in the 1990s. However, the Tiger 131 does not run on its original Maybach HL210 engine, as it was taken out to be used as a separate display; rather, it uses the HL230, which was mostly used for the Tiger II. It is still there as a display and remains the museum's most popular exhibit.

=== In-game description ===
"Work on the creation of a heavy tank began in 1937. Only after the attack on the USSR were the tactical and technical requirements needed for this new war machine met. The tank was designed by the Henschel company, led by Erwin Aders.
Production was handled by Henschel and Weggman factories, which made about 450 tanks from July 1942 to August 1943.

The first 495 vehicles included equipment that enabled the crossing of water obstacles up to 4 meters deep. Beginning with the 251st tank, the Maybach HL 230 P30 engine (600 hp) was replaced with a Maybach HL 230 P45 (700 hp). The Tiger was armed with an 88 mm 8,8 cm KwK-36 L/56 gun, which was a tank version of the famous Flak 18/36 anti-aircraft gun. In the spring and summer of 1943, the tank received smoke grenade launchers and mortars for launching anti-personnel mines.

The Pz.Kpfw. VI Tiger entered service with heavy tank battalions. The tanks were first used in the fall of 1942, on the Leningrad front, in the 502nd heavy tank battalion. In December 1942, in North Africa, Tigers entered service with the 501st battalion.

The first tanks which arrived often broke, owing to the haste with which they were put into mass production. The vehicle was very heavy, with low maneuverability. It consumed 10 liters of fuel every 1 kilometer. A full fuel tank, 567 liters, was enough for only two and a half hours of combat work, which was one of the tank's major drawbacks. But this was all compensated for by the battle machine's simplicity and ease of operation. Tank operators who served in Tigers were constantly praising its transmission and steering. The tank's armor also gave the crew a high chance of surviving battle, even if the tank was disabled."
