Pros and Cons
- 152mm gun is immediately available for research and does not require the upgraded turret/suspension, making for a very easy stock grind
- Good rate of fire and penetration (for tier 6) with the 107mm ZiS-6
- Very strong gun mantlet
- 152mm M-10 can one-shot many tanks of tier 6 (and occasionally, some tier 7's) and lower (except for the TOG II*)
- Fear factor and reputation - people will often play differently to avoid having the gun pointing at them, and may even retreat
- Massive splash radius can damage multiple tanks at once
- Above average HE damage can cause significant module damage
- Tracks can eat a lot of damage if angled correctly
- HE shells from 152mm deal heavy damage even without penetrating, making the KV-2 one of the few heavy tanks that doesn't mind at all when bottom tier in a match
- Low speed and terrible maneuverability; favorite target of SPGs
- Large and tall silhouette
- Poor view range
- Poor accuracy and aim time on all gun options
- Massive reload time on 152mm
- Severe threat from 152mm makes the KV-2 a priority target for most players
- Armor remains unchanged from the tier 5 KV-1
- Turret's flat surfaces are more easily penetrated than the KV-1's
- Horrifyingly slow turret traverse (one of the slowest in the game)
- Turret ring and main gun are easily damaged
- Poor gun depression
In the right hands, this can be a very powerful tank, capable of fighting against Tier-8 tanks with proper application of its strengths and weaknesses. This tank can be used as a close range brawler using the incredibly powerful M-10 howitzer and as support tank from the second line with the powerful 107mm ZiS-6, although the T-150 is able to use the ZiS-6 to better effect. The most basic and most important lesson is: never venture alone. Stay close to your allies. You will need them to cover you while you reload. They can also pick off any light tanks that attempt to circle you. Do not judge the KV-2 by its "derp" turret, as it is an extremely dangerous tank.
Since this tank's upgrade to a tier 6, it has made a massive impact on medium tank companies. This tank is actually much more effective in TC's than it is in standard battle, since it will be facing tanks at or below its tier. Out of the three Soviet tier 6 heavies, however, the KV-2 is considered the weakest by most players, simply because of the fact that it is so incredibly slow and sluggish when compared to the KV-1S and even the T-150. The best advice for this situation is, again, to fight with teammates and never lead attacks, especially if you are packing the 152mm. Also, keep in mind that the KV-2's extremely large profile is a tempting target to other tanks and artillery, so caution must be taken when crossing open fields or crucial choke points, and be sure to always keep your back clear and a safe escape route in plan.
Another thing to note about the KV-2 is that the color of the reticle does not really matter. The massive damage of the 152mm HE shell means that every enemy is almost guaranteed to receive damage even without penetrations, with the shell usually dealing about 300 if it doesn't penetrate, reduced by enemy armor thickness. The damage is so massive that the HE shell can damage the T95 from the front. If it does penetrate though, the tank on the receiving end of the shell is usually blown off the map and hurled into the sun or has a large chunk of health missing together with a crippled crew and damaged modules.
To achieve this, you need to take note of where on your opponents to hit for big damage. Usually, if in doubt, go for hull sides or from high ground onto top armour, where armour is thinner than 85mm and penetration is readily achieved. However, certain opponents are highly vulnerable to the KV-2's gun:
- It goes without saying that tier 4 tanks, tier 5 tank destroyers (excluding the AT 2) and tier 5 mediums will be almost always instantly killed with a direct hit from the 152mm howitzer.
- KV-1, KV-1S and KV-2 can be killed by hitting driver's hatch in front armor. Flat parts of KV-2 turret armor are also weak as well as KV-1S sides.
- Churchill I (with upgraded turret) and Churchill III can be killed hitting their turret, or, even better, get to their sides, as they are big, flat and very weak. This goes the same for the Churchill VII
- French tanks are a good choice of target; their weaker armour makes them vulnerable to HE. ARL 44 has very weak sides and turret side. However, beware of their speed and autoloaders, and do not try this frontally against their AMX AC series tank destroyers.
- The T1 Heavy Tank and M6 have vulnerable 40mm hull sides. A shot there is almost certain death for them.
- All of Germany's 30 ton prototypes have bad armour from the front and the HE shell should penetrate fully.
- Should you be lucky enough to close the gap on a Pz.Kpfw. V Panther, but he's facing you, aim for the lower glacis or the machine gun weakspot. The upper front plate is a 50/50 tossup. The lower glacis aiming strategy is also applicable for the Jagdpanther.
- VK 36.01 (H), Tiger, Tiger II and Ferdinand have vulnerable sides and HE should do maximum damage.
- Consider ARL V39s and Churchill Gun Carriers easy meat for the howitzer, especially the former.
- SU-100Y and SU-152 can be penetrated by hitting front armor next to gun mantlet
If you aren't facing any of these, but the tank has bad side turret armour (80mm or so), have your backup distract the enemy, wait for them to rotate the turret towards your support, then unleash the derp onto their turret side. If you're lucky, you'll blow their ammo rack up or penentrate through the thin side armour for massive damage. A dead gunner or loader is a bonus.
While having a 100% crew and full set of equipment helps all tanks, the KV-2 is particularly aggravating to drive if using a fresh 75% crew. Consider a Rammer and GLD mandatory. Vents and a crew with the Brothers in Arms skill are very helpful as well. Because of this, the KV-2 is not recommended as the first tank to unlock and purchase from the KV-1. It's best to come back once you have a good crew to move to it, and the credits to afford the expensive equipment.
- The V-2K engine and the 10RK radio carry over from the KV-1 and should be installed immediately upon purchasing this tank.
- Begin by researching either the 152 mm M-10 or the 107 mm ZiS-6. The stock suspension can handle the weight and the second turret isn't required.
- Next upgrade the suspension.
- Go from there.
