What weapon to install on the IS
With the D-25T gun the IS is good in close combat
, especially on city maps. Having installed this weapon, choose an area with shelters - buildings, rocks, hills, where you can wait out reloading, and the confrontation with your opponent takes place face to face.
D-10T is better suited for neighing at medium distance
. You will feel confident on maps with open terrain, where you can hit enemies at a considerable distance.
Most players choose the D-25T gun, because dealing 390 damage with one shot is a powerful argument. But to make a choice, it is better to try both and choose the most convenient for yourself.
On IS-7 for World of Tanks. The legendary Soviet ten, also known as “grandfather”, “lunokhod”, “seven”, is worth attention if only because it was the first tenth level heavy vehicle introduced into the game at the same time as Mouse. This happened at a time when the French drums were in Wargaming's distant plans, and the top art was level six. More than a dozen tanks have been introduced and removed from the game since then, but the IS-7 remains, having undergone minimal changes. Let's try to understand the secret of his success.
Crew:
- Crew commander (radio operator);
- Gunner;
- Driver mechanic;
- Charging.
Learning additional skills for the crew:
Standard crew:
1 | 2 | 3 | 4 |
For the first slot, we teach all crew members, except the commander, the “ Repair” , and for the commander the “ Sixth Sense” skill - the “Repair” skill speeds up the repair of damaged modules, and the “Sixth Sense” will allow you to determine whether his tank has been detected by the enemy. Also, all crew members need to learn the additional skill “ Combat Brotherhood” , which will improve the level of proficiency in the specialty - be sure to learn it all at once, preferably used in the second or third slot.
- the Eagle Eye skill , which increases the viewing range.
- For the gunner we learn the skill “ Smooth turret rotation” , which reduces the spread when turning the turret; and the Sniper , which increases the chances of causing damage to modules and crew members.
- For the driver mechanic, we learn the “ Smooth Move” , which reduces the dispersion of the gun in motion; and the Off-Road King , which reduces drag on soft to medium ground when driving.
- For the infector, we learn the skill “Non-contact ammo rack ,” which increases the strength of the ammo rack; skill “Desperate” , which reduces the reload time when less than 10% strength remains.
Where to push the IS-7? Penetration zones and weak points.
IS-7 is a reliable friend in the hands of an ally. If the seven is controlled by an opponent, it turns into a formidable obstacle. Let's determine where to punch the IS-7 using a practical example.
From the diagram it is clear that the optimal penetration zones for the IS-7 are the sides under the screen and the stern. If the maneuverability of the tank allows you to bypass the “grandfather” from the stern, it is better to do just that. Owners of precision weapons can try to target the area between the screen and the track or shoot at random between the rollers.
The situation in urban battles is somewhat different. In such a situation, you need to know where to throw the IS-7 in the clinch. There are two main points:
- Roof of the tower. Tall tanks with good air defenses, like the E100 or Tapkolv, can penetrate seven into an unprotected turret cover. The same applies to art.
- Rangefinder. It is located directly under the gun. By shooting at him, you can not only cause damage, but also break the enemy’s optics, significantly reducing visibility.
Equipment, gear and ammunition:
List of equipment that can be installed on the IP:

On the first slot we install complex Rammer equipment, which increases the reload speed by 10% . On the second slot we install complex equipment: Reinforced aiming drives, which increases the gun aiming speed by 10% . In the last slot we install complex equipment Improved ventilation, which increases the level of proficiency in the main specialty and additional skills by 5% .
Equipment:
List of equipment that can be installed on the IS:
The equipment should be equipped with a standard set of equipment: Small repair kit , Small first aid kit , Hand fire extinguisher . The fire extinguisher can be replaced with Lend-Lease oil , which will increase engine power by 5% . For tournaments or when there are a lot of credits, you can replace the fire extinguisher with Extra Ration 10% to all skills .
Ammunition:
122 mm D-25T gun , we’ll take most of the armor-piercing shells, but against more armored enemies it’s worth taking a few premium sub-caliber shells, which will make the game easier. High-explosive fragmentation shells will be useful for us to shoot down the capture of the base and finish off opponents with a small margin of safety. The total ammunition load is 28
shells.

More detailed information about the technique:
The IS battle tank is part of the continued development of the KV-85, which is why the mobility and power of the gun have been preserved. Thanks to the 122 mm, it is possible to inflict great damage on various tanks, but penetration is very small and is only sufficient against the seventh level. Poor accuracy and long aiming times allow the weapon to be used only at short and medium distances. Such a gun makes the game very difficult against the eighth and ninth levels, since you need to shoot at weak points, and the accuracy and aiming speed are very poor. The armor on the front of the hull is very weak, although there is not much slope, and there are also a large number of vulnerable spots. A low safety margin and a small damage per minute indicator do not allow you to fight head-on with enemies of your class level, since the chance of losing is very high. Thanks to its normal driving characteristics, it can take on battles in a group of medium tanks.
Bottom line: The IS tank is only suitable for short and medium ranges. Although this tank is popular, its characteristics are inferior to other tanks in its class. However, the next combat unit will bring a lot of impressions to any player.
Combat effectiveness
The IS, in fact, is a development of the KV-1S. Mobility and guns are on par, but the IS tank has 120 mm plates on the forehead, as well as their changed angles compared to the KV-1S and KV-3. The armor, at first glance, is quite good, but the model presented in the game is the IS-1\IS-2 model 1943, with an indirect forehead and the presence of a 60-mm part on the forehead, which significantly reduces the level of protection of the tank. The D-25T gun allows you to inflict a lot of damage on different tanks, but the armor penetration is quite low, and therefore there are often situations in which you need to shoot at the weakened areas of the enemy tank, which is difficult with not very good accuracy. The visibility of the top turret is also at the level of all Soviet tanks in the game, that is, it is not always enough to spot the enemy. The mass of the tank, of course, makes it possible to ram enemies, but this should only be done with tanks up to the eighth level: ramming the ninth, tenth level can make things even worse for the IS itself, and not for the enemy. The range of a top-end radio also sometimes makes it impossible to observe the actions of enemies and allies on the map. However, the vertical aiming angles are quite good, which gives some advantage when shooting from behind the mountains. The amount of HP in the top configuration is higher than some tanks, but it is not an advantage either - the Henschel Tiger and the Porsche Tiger have 200 units more HP, the T29 has 20 units more, which is not very pleasant.
At the top of the team, the tank is well suited for a swift attack at the head of a squad, but if you get stuck, you should look for cover, since head-to-head firefights with tigers and 29 are more likely to be beneficial for them. Thanks to decent speed and maneuverability, and also from the middle and end of the list, the IS fits quite harmoniously into the battle formations of the ST - you just need to remember that the senior ST level, especially the China and the Cockroach, are much better armored than us, so it’s their job to “tank” . For the same reasons, one should not be shy about using the “ST-manner” in close combat with equal TTs - rolling to the sides/rear, circling, “dancing” away from the enemy’s barrel - all this significantly increases the effectiveness of using the IS.
Advantages
- Not bad maneuverability for a heavy tank.
- Good forehead armor.
- Rapid-firing and powerful weapons.
- Good communication range.
- Small dimensions of the tank.
- A good overview of the top tower.
- Quite a big Alpha Damage top gun.
Flaws
- Lowest armor penetration among Tier 7 heavy tanks.
- Thin turret forehead armor.
- The presence of many weakened zones on the forehead and tower.
- Small ammunition load for 122 mm guns.
Tactics for playing with guns:
IS with D-5T, D-5T-85BM
With these guns, the tank can fire frequently and accurately over fairly long distances, but they lack armor penetration, especially the D-5T. Even for level 6, these guns are already quite bad, and given the type of tank, these guns should generally be replaced with better ones. Therefore, the only role of a tank with these guns is to destroy light and medium tanks of levels 4-6, divert fire to itself, try to damage higher tanks with high-explosive shells, and never attack alone.
IS with D-10T
With this weapon, the IS shoots often, accurately at long distances and with a high probability of penetration (for levels 6-7). The armor penetration is quite enough to penetrate tanks such as the IS-4 and IS-3, but the high-explosive projectile is quite weak, which is very bad if the tank encounters tanks like the VK4502, IS-7 and others. The tank most likely will not have time to enter the clinch (and it is pointless) to shoot triplexes and hatches, so only land mines remain. The roles of the tank in battle are supporting the attacking group, protecting the base from medium and heavy tanks of levels 5-7.
IS with D2-5T, D-25T . This weapon is more like a so-called “shotgun” - the spread is large, but the damage is also considerable. You can successfully destroy tank destroyers like the SU-85 with one shot and force the T-34-85 and others to turn around. The damage of a high-explosive projectile is enough to surprise 8-10 levels. The roles of the tank in battle are supporting the attacking group and defending the base.
Choice of weapon.
After fully upgrading the tank, you can choose a weapon depending on your playing style: 100 mm D-10T and 122 mm D-25T. The first is characterized by good accuracy, rate of fire, low cost of shells and low damage. The D-25T is powerful, but rather inaccurate and, although it has a fast reload, it is slower than the D-10. "Sotka" can be installed on a tank if it will serve as a support tank or an ambush tank - it is quite possible to shoot at medium and long distances into vulnerable areas of an enemy tank with such accuracy. The D-25T is usually installed on those tanks that perform the role of an assault tank tank - when penetrated, high armor-piercing damage is inflicted, and a high-explosive shell damages the modules of the enemy tank and reduces its effectiveness. Both guns have a high rate of fire, but the D-25T has more damage per minute.

Historical reference
As soon as the first ones left the factory buildings in 1944, the designers immediately decided to improve the new breakthrough tank. To create competition, the production task was distributed between plant No. 100 and the Chelyabinsk Kirov plant.
A new turret was installed on the used chassis, and the hull received a characteristic “pike nose” (plates of the upper frontal part located at an angle). The redesign also affected the interior space. By reducing the radio operator-gunner with the front-mounted machine gun, it was possible to increase the armor and increase the volume of the fighting compartment.
Contrary to popular belief, IS-3
did not have time to participate in the Second World War. The first batch was only able to parade at the Berlin Parade of the Allied Forces, terrifying foreign military attaches. But after that, these monsters appeared in all significant regional conflicts, from the suppression of the Hungarian uprising to the Arab-Israeli wars.
