Description

The KV-2 (1939) is a rank II Soviet heavy tank with a battle rating of 3.7 (AB/RB/SB). This tank was introduced during the Closed Beta Test for Ground Forces before Update 1.41. One of the most infamous tanks in the Soviet tree, the KV-2 introduces the concept of heavy-calibre armaments that will trend on other Soviet heavy tanks.

The KV-2 is a modification of the KV-1 that mounted a 152mm howitzer in order to provide support to infantry against fortified positions. The large heavy turret, necessary to mount the 152 mm howitzer, results in a slow traverse time. Its gun is an effective breach weapon, designed against fortifications. Despite effective usage, very few were made, with the majority being lost due to breakdowns.

The KV-2 is a behemoth of a tank, which players feared due to the mighty punch of its 152 mm round and its distinctive profile. However, these traits also serve as the tank's weaknesses. While the KV-2 can still be an effective force on the battlefield, it is currently outperformed by nearly all other Soviet vehicles.

The KV-2 is incredibly sluggish in speed and manoeuvrability. The original KV-1 is already slow as is, but the KV-2 added a huge and heavy turret that increased the total weight from ~46 tons to ~52 tons. Top speed for the vehicle on flat ground is only about 30 km/h, and accelerating is very slow to get the tank up to this speed. Unless moving forwards at a certain gear, the KV-2 is also very hard to turn on even ground.

The large turret housing the 152 mm howitzer is a huge target on the KV-2, a more enticing target than the hull. The profile makes concealing the tall, heavy tank difficult, while the turret armour is relatively poor all-around at 75 mm. Not to mention that there will always be ammunition inside the turret, so a penetrating APHE shot has a very high chance of detonating one of these rounds. At its battle rating and rank, most enemy tanks have the capability of penetrating and eliminating the KV-2 through the turret, not to mention even some of the lower rank ones have powerful enough guns to deal with the armour.

The 152 mm gun is perhaps the most iconic and niche weapon in the Soviet tree. Coupled with the heavy turret, it produces a slow turret traverse to get the gun onto a target. The turret also presents a narrow gun depression and elevation (-5° and 12° respectively). However, the biggest factors to consider is the ammunition for the 152 mm. Although the vaunted High-Explosive rounds would be the perceived preferred round for the heavy gun, it does not do as well against the typical armour with only 54 mm of shrapnel penetration, requiring a precise hit against the enemy roof or belly armour. Even the other AP rounds, the anti-concrete O-530 and PB-35 APCBC rounds have relatively mediocre penetration for the battle rating. Firing at a relatively low velocity of ~500 m/s, the heavy rounds will be hard to lead against targets at ranges up to 500 meters. After firing, the infamous long reloads occur that can take up to 30 seconds even with a full crew, leaving the KV-2 vulnerable to any attacks that will more than likely cripple or destroy the KV-2.

A surprised and unangled KV-2 with line-of-sight armour thickness. Even in this state the KwK 40 (Panzer 4) will have problems penetrating at ranges >500m

The normal role of a heavy tank is to bring armour and firepower to support the lighter, faster tanks to hold strategic points they have captured. However, the massive profile of this tank and the majority of flat 75 mm armour means that even with proper angling and cover, the KV-2 will be unable to hold points for long. The KV-2 easily identified by even the least experienced players and as soon as it fires one round, it will be out-manoeuvred on and forced to retreat or be violently removed. Additionally, artillery and aircraft will often force the KV-2 out of positions if not outright destroy it due to the KV's abysmal speed and massive size. Lastly, the KV-2 has no machine gun to deal with air or lightly armoured targets, meaning once the howitzer fires, that is it for around 30 seconds. Even most anti-air vehicles can effortlessly overrun and destroy the KV-2 if it is over-extended or alone. Couple that with this tank's inability to provide effective long range support and players will have a difficult time finding their niche with this vehicle.

This KV-2 behemoth is also lovingly referred to by the following nicknames:

• "the barn"
• "the mountain"
• "nuclear death cannon"
• "The Tower of Stalin"
• "тнe haиd of Sтaliи"
• "King of Derp"

Armour type:

• Rolled homogeneous armour

Armour	Front	Sides	Rear	Roof
Hull	75 mm (31°) Front plate 70 mm (72°) Front glacis 25 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 while tracks are 30 mm thick.
• With its straight angles the KV-2 can easily be angled in the diamond direction (30°). Improving the line of sight thickness of the chassis to 100mm frontally and 130mm on the side. The turret achieves at 30° up to 90mm of steel, however, the turret ring remains a weak point on all angles.

Armaments

Main armament

The 152mm howitzer is one of the most devastating guns in the game, if its shell penetrates. Almost no vehicle can survive a penetrating shot. Although it has a lot of bullet drop, the drop is consistent and the experienced player can hit target past the usual short range. Remember to pick enough types of ammunition for any situation. However given the half minute reload spaded and with an ace crew, you'll have to prepare your ammo type beforehand a conflict.

• G-530 (AC)
  The "Anti-Concrete" round has the same speed as the HE shell with a decent amount of penetration for nearly all Rank III tanks. In ranges greater than 1,000 m, the OF-530 shell should be loaded to effectively deal with any vehicle including heavy tanks. Compared to the PB-35, it has much greater speed, improving long-range accuracy.
• OF-530 (HE)
  The "High-explosive" shell requires careful aim as, despite its infamous power, a solid hit on the front of an enemy tank would not necessarily defeat the enemy. One must preferably aim beneath tanks or below the gun mantlets to sneak into thinly armoured portions such as the roof or belly armour.
• PB-35 (APCBC)
  The APCBC shell gives the most slope benefit but is the least penetrating and also has the worst accuracy of the shells, given due to its abysmal slow velocity of 436 m/s (975 mph). Thus it is not advised to be used except in close range combat.

Usage in the battles

The old peek-a-boom tactics, and staying behind others is still the best method for employing this "heavy tank". Roll forward, take the shot, and then pull back for the over half-minute reload time, and then repeat. Close range brawling is a bad idea due to certain characteristics on the tank. Make sure to plan the route ahead of time make sure to avoid large distances in the open, this is a slow moving tank with a large profile making it an easy target for long barreled guns. It is recommended to have a work with a squad mate or other friendly tanks to cover the KV-2 during the reloading phase.

Most tanks with a high-velocity cannon can cripple the KV-2 through the turret. As such, pretty much all tanks at its battle rating should be taken account of. Rely on always getting the first shot off, else the enemy tank is more than likely to destroy the KV-2.

Another type of vehicles to worry about are the very small tanks like the M22 Locust and the ASU-57 as these can get right under the tank's gun depression and fire away at weak points with little risk of return fire by the KV-2.

Arcade battles

In Arcade, the target lead indicator make the slow, but long-range penetrating PB-35 APCBC a destructive force to be afraid of since ranging is a lot easier for the low-velocity shells. Always conduct attacks via "Peek-a-boo" tactic in that stay behind cover while searching for targets, then pop out when a target presents itself to fire before returning back to cover to reload.

One must be conscious and use the map terrain to their advantage. On more open maps like Karelia and Carpathians, the KV-2's speed and low velocity will make traversing the battlefield while sniping long-range targets difficult. However, one could hang back and snipe unsuspecting and immobile targets, while at the range most return fire would more than likely bounce off the armour. However, be wary of more penetrating guns like the 75 mm on the Panther and the 76 mm on the M4 Shermans that easily piece the front turret armour.

Smaller maps benefit the KV-2 in that the low shell velocities are no longer a big detriment to the combat ability, plus it could make the most of the initial penetration values in close-range battles. However, enemy tanks in close-range will also have an easier time penetrating the KV-2 front armour, or flanking around while reloading the gun. In these cases, situational awareness and friendly support is the key to victory and survival of the KV-2 in the smaller maps.

Realistic/Simulator battle

Realistic and Simulator modes are taxing for the KV-2 as the removal of the target lead indicator can make long-range fighting with the 152 mm a chore.

The most important thing in these game modes, due to the lack of target markers, is the vision. The binoculars are the greatest assets. Keep the turret in a well-angled position while scouting for targets with the binoculars or normal eyesight.

Since the usual fighting ranges exceed 600 m, getting hits without aim assist with the howitzer are rare. Though close-range fighting can fix this, the close-quarters battle is not a tactic the KV-2 should indulge in alone without supporting teammates to cover for the tank in case of flankers. A tip for long-range fighting is to utilize the OF-530 HE shell in the first shot, with spare G-530 anti-concrete rounds for the follow-up. These two rounds share the same ballistics, so the HE shell can be fired first to gauge the distance. If it lands close to the enemy and hits, chances are it will either destroy it or cripple its mobility, plus the impact of the explosion will alert teammates of the presence of an enemy tank at the area of firing. If the enemy tank still remains after the OF-530 shell, the next loading G-530 AC shell can follow through the same ballistic path and destroy the enemy via a penetration.

Counter-tactics

Getting close: Probably the most difficult part, if spotted a 40 kg shell will soon be on its way to ruin someone's day. Thus sneaking up, or attacking, from outside the KV-2's field of view is advised. Of course, after the KV-2 has fired, a window of opportunity and hope will open up. With moving up and aiming two shots can be placed on the moving Soviet tower tank. An attack route from the side or rear is preferable, not only is it a blind spot, but the turret traverse is so awful on the KV-2 that it will not have the time to react fast enough. Just make sure to hit, or the tank will be alerted and counter-attack.

Shooting: Targets should be the gunner (right side) to stop the loading process and the loader to reduce loading time. If shooting APHE shells, two penetrating hits will often take out the gun breech as well, stopping the reload and the ability to return fire entirely. The easiest way of performing these hits is via the turret ring which will always not be angled at certain parts from the front. If APHE shells hit below the side hull, it will possibly detonate the main storage of ammunition, resulting in one-shot destruction. If that is not the case the gunner, commander, cannon breech, loader, and ammunition and turret ring will be damaged or wounded.

Shooting a KV-2 from the side is much easier, just one massive turret reaching into the sky. But do not shoot anywhere! The tracks will often eat shots and most KV-2 drivers are by now smart enough to not fully load up their KV-2, leaving the rear turret empty of shells.

Modules

"Parts" and "FPE" should be the first target for unlocking. While the mobility of the KV-2 is quite bad, the turret traverse and accuracy is worse. Thus "Horizontal Drive", "Adjustment of Fire" and "Elevation Mechanism" should be prioritized after the first set of upgrades. The "PB-35" shell unlock can be ignored as it is only a marginal upgrade compared with the GF-530 stock shell.

Pros and cons

Pros:

• Huge howitzer, dealing high damage with incredible force
• Fear factor, the sight of this behemoth tends to send smaller tanks fleeing in terror
• Acceptable armour, especially for its rank
• Able to destroy higher rank tanks
• Bouncy hull and turret, the chassis may effectively absorb shots as well
• Many experienced tank drivers would dread the characteristic, map-echoing sound of the 152 mm howitzer being fired
• As is the case with all Russian 152 mm armed tanks, the KV-2 can one-shot any tank or tank destroyer in the game with a single HE shell to the turret or rear hull
• Has the armour of the KV-1 which will stop most Pz.III and Pre-T-34-57 shots

Cons:

• Long reload, resulting in difficult 1-on-1 fights since missing gives the enemy an opportunity to counter
• Slow rotation speed of the turret means that flank attacks are difficult to respond to
• Tall turret is very vulnerable from the side and difficult to hide
• If more than 19 rounds loaded, the ammo fills the weak spot ammo racks in the sides of the turret
• A characteristic trait of Soviet tanks, the KV-2 has terrible gun depression, worse when compared to other Soviet tanks
• Driver's viewport is a juicy weak spot, easily exploitable by experienced players
• Has a tendency, although a rare but dreaded occurrence, to overshoot targets at close range when using the sights
• Large silhouette

History

Development

The start of the KV heavy tanks began after the heavy tank T-35 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-1 tank, which was named after the then Soviet Defense Commissar Kliment Voroshilov.

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 outperformed 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 cannon also gave it a huge firepower boost compared to the usual 37 mm in use by other countries. However, the design was found to be difficult to steer, the transmission was unreliable, ergonomics was poor and vision was limited, plus with its 45-ton weight, it was a very heavy 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 really was. The main variant of production before World War II broke out was the KV-1 model.

KV-2

Despite its superiority on the battlefield, some observed that the KV-1's armament was not enough to destroy some of the Finnish fortifications that they encountered. For this, a request to mount a 152 mm howitzer on the KV-1 was made and resulted in the KV-2 with its extremely large turret and an increased weight of 52 tons. The KV-2 suffered from a very high profile, low speed, and was to turret heavy. Compared to the KV-1 height of about 9 feet, the KV-2 was at 11 feet tall. The increased weight of the tank slowed it down drastically, and the very heavy turret mixed with a low-powered traverse speed meant that the KV-2 can only traverse on level ground, as a slope would cause the turret to start turning with gravity. The combat ineffectiveness and flaws of the KV-2 came to light and was only put on limited production due to them, resulting in only about 334 units being produced from 1939 to 1941.

Combat usage

During the opening stages of Operation Barbarossa, the KV tanks came as a huge surprise from the Germans as they had no prior intel about these tanks, resulting in a lack of capable anti-tank weaponry that could destroy these tanks, aside from 88 mm FlaK guns. The KV-2 served alongside the KV-1 in stalling the German Offensive to Moscow. During the Battle of Raseiniai, in Lithuania, a single KV-2 was able to hold up the entire 6th Panzer Division for a full day by firing at them from a concealed location before it ran out of ammunition, ending with about two dozen tanks destroyed.

Due to the low quantity of KV-2 produced, they didn't see much service past the opening stages of the war due to loss from attrition or mechanical failures, however, 10 were still in service with the Voronezh Front on 4 July 1943 for the battle of Kursk. These were transferred to the 3rd Mech Corps on 9 July, and by 18 July only 1 was left serviceable - 5 were destroyed on 12 July, and 4 are recorded as being in repair from 13 July.

Survivors

Only one KV-2 is left intact as a survivor of the war, it is housed at the Central Armed Forces Museum in Moscow.

In-game description

This tank came into service in the Red Army in 1940 and was an assault tank intended to be used to overcome long-term defensive positions. The KV-2 was armed with a powerful 152 mm M-10 cannon installed in its tall armoured rotating turret. This weapon was shot with separately loaded shells, so its combat rate of fire was not high. The howitzer had relatively good characteristics. Its armour-piercing 52 kg round with a 436 m/s muzzle velocity penetrated a 72 mm thick armour plate at a distance of 1500 m at a 60° angle. For firing on concrete fortifications, it possessed a 40 kg concrete-piercing shell with a 530 m/s muzzle velocity. All these vehicles were equipped with a 71-TK-3 radio set. The vehicle was armed with three additional 7.62 mm DT tank machine guns. One was paired with the howitzer, the second mounted in the rear turret wall, and the third mounted as a bow gun in the underturret box's frontal plate to the driver's left.

By 1941, 330 of these tanks had been produced in total, and production ceased at the beginning of the Great Patriotic War. In mid-February 1940, several of these heavy tanks were put to the test during the breaking of the Mannerheim Line. They broke through stone fortifications and destroyed pillboxes at close range, allowing infantry divisions to pass through areas previously closed to them. Furthermore, its strong armour could survive heavy fire from the enemy's anti-tank artillery. In the first years of the war, the KV-2 was practically invulnerable to all forms of anti-tank artillery. A number of captured vehicles of this type were used by German troops.

The tank had some serious flaws. Its mobility on the move and in combat was seriously limited by its high weight and issues with its clutch and transmission. When the vehicle was at a slight tilt, the turret became extremely difficult to turn. Its ammunition complement for its main gun amounted to only 38 shells.
