On today’s menu we have the IS-3 (AKA Object 702). This is a tier 8 soviet heavy tank that packs a punch powerful enough to shake those Tier 10 tanks. With this machine using the 122mm BL-9 you will finally be a threat to everything, even IS-7 and Maus tanks.
Previous tank: IS-2
Next tank: IS-8
Stock Tank Specs:
You start off with the 122mm D-2-5T gun, which you bring back from the KV-1S. Besides its decent damage, the gun doesn’t have enough penetration for a T8 tank and is so inaccurate that chances are you will hit the sun rather than what you were aiming for. After getting the BL9 you will have a dependable gun with decent penetration and good damage. The accuracy is improved a lot and you now have an actual chance of hitting even the moon. The IS-3 has decent frontal armor and since it’s sloped at a good angle it will deflect a relatively large amount of stuff. It side and rear are quite weak and will rarely bounce shots. Turret is well armored and the tank has a low profile, which makes it a harder target at range. Unfortunately, that means that at close ranges, bigger vehicles can hit the vulnerable roof of the IS-3. A good thing to note is that this is one of the fastest heavy tanks in the game. With its top speed of 38 km/h it can very well be used as a medium tank hunter, or an effective brawler.
Being a tier 8 heavy, IS-3 is your first high end tank. It can penetrate and kill EVERYTHING in the game if driven well.

Use your IS-2 crew, it will save you some brain cells.
Armor scheme currently in use
1. IS-3 (stock) / Max.capacity 50.56 / Turn speed 27 degrees per sec.
2. IS-3M / Max.capacity 53.9 / Turn speed 30 deg per sec.
The suspension is not the first thing you need to get, but do consider it for an elite IS-3 as it does make a difference!
V-11 – 650 h.p. – 15% chance for fire on impact
V-2-54IS – 700 h.p. – 12% chance for fire on impact
Overall, you have a pretty powerful and reliable engine. Unlocking it will help unlocking the rest of the Soviet line.
10RK – range 440m
12RT – range 625m
R113 – range 730m
Suprisingly, getting a better radio soon is advisable this time. 440m is just not enough sometimes. Best radio is credit to the team tough.

I suggest getting the better turret ASAP. Its much tougher and can deflect quite a lot of shells from its front. The improved view range also helps quite a bit. Unfortunately, both turrets suffer from OMG AMMO RACK syndrome. The entire side and parts of its rear contains ammo, meaning that a powerful hit there may turn you into a wreck. Another problem, is that since your IS-3 is so small, (which also makes you a smaller target) any tank larger than you can shoot the top of your turret and penetrate easily when in CQC. Never believe you are safe when facehuggin a bigger tank.
122mm D-2-5T and 122mm D-25T
Average damage: 390/390/465
Accuracy (100m): 0,46
Aim time: 3,4
The first two 122mm guns are pretty similar, they only differ in the rate of fire, with the second one firing about 1 more round per minute. Do equip the D-25T as its 1 round that sometimes decides the outcome of a battle!
You also have the 100mm D10T gun, which is basically worthless for this tank as it has the same penetrations as the 122mm ones and has a lower damage per minute ratio. Good for a tier 7 medium tank or the IS-2, but not here.
Average damage: 390/390/465
Accuracy (100m): 0,40
Aim time: 3,4
The damage and cost is the same as the other 122mm guns, BUT you get 50 more penetration and 0.06 accuracy (that's a lot). This gun makes fighting T32 and Tiger 2 tanks much easier. You can finally penetrate their front as long as it aint too sloped. All tier 9 meds can be damaged and so can all tier 9 heavies if hit in the weak spots, usually lower hull. When confronted by something heavy like a Maus or an IS-7, try to hit their weak spots or load HE rounds. Researching this gun here and now will make the IS-8 and the ST-I an easier grind.
Premium ammo is APCR. This ammo type gets a normalization bonus against sloped armour just like normal AP and is usually relatively effective even against spaced armour . However, unlike HEAT ammo it loses penetration with distance. With 265 mm of pen, that is usually plenty to assure penetration even against tier 10 tank destroyers and heavy tanks, provided the IS-3 avoids their strong points.
Proposed upgrade path:

Comparison with its peers:
IS-3 vs KV-4
The IS-3 does more damage per shot and is also smaller. KV-4 has more health points and a mor accurate gun. The KV also has more armour, though mobility is inferior compared to the IS.
IS-3 vs Panzer VI Tiger ausf B
Both tanks have 225mm of penetration. IS-3 does more damage per shot than the Tiger, but fires slower and is not as accurate or as fast in aiming. The KT has better gun depression, more health points and is better at ramming. IS-3 has a slightly tougher turret and side armour, but weaker frontal and rear armour. It does have slightly smaller weak spots but cant angle itself as much as the Tiger 2.
IS-3 is better vs smaller tanks than KT, thanks to its all around armor.
King Tiger has a better frontal plate than the IS-3. It can be sloped too.
IS-3 is a faster vehicle, but the bigger KT can ram better.
IS-3s turret may be vulnerable up close, but its harder to damage than the KT at long range.
IS-3 has worse gun depression, accuracy RoF and aim time than KT, but superior damage and HE shells.
IS-3 vs VK 4502 (A)
Both tanks offer similar styles, but the IS-3 has better overall armor, though the VK can slope itself. The VK is slightly more agile and is a much better medium tank hunter than the IS-3. Its gun is more accurate, fires faster and aims faster, but loses in penetration and damage per shot. Its gun depression is slightly better.
IS-3 vs T32
T32 and IS3 are about equal in hull armor, but T32 has an invulnerable turret. IS3 has a superior gun in all stats except RoF and aim time. T-32 has better gun depression and is also not a slouch either.
IS-3 is again better vs small tanks thanks to side armor.
T32 can turret-hug Tier 10 tanks into submission.
T-32 has much better gun depression.
IS-3 gun is better than T-32 gun on almost all fronts.
Mounts the D-25T and IS-3 turret. The tank never saw action in Europe. However several of these beasts were shown on the Victory-Day Berlin Parade. Rumor is a regiment of IS-3’s was unleashed against the Japanese in Manchuria during the summer of 1945 and I think you get the rest...the word “meat-grinder” should go in there somewhere. The tank remained in service with the soviet army for about two more decades and a modernized version called the IS-3M appeared in 1960.
