Description
The KV-1S is a Rank II Soviet heavy tank with a battle rating of 4.0 (AB/RB/SB). It was introduced in Update 1.57 "Battle March". A lightened KV-1 made to improve its manoeuvrability, the KV-1S has less overall armour than the original design but keeps its same lethality with improved speed.
Compared to the KV-1 L-11, side and rear armour are decreased to 60 mm, lightening the vehicle and increasing its speed to maximum 43 kph. A new turret was installed, presenting a smaller profile, thicker armour, and better angling all around. The armament is also changed to the ZIS-5, the equivalent of its successor and the T-34's F-34 guns.
General info

Armour type:
- Rolled homogeneous armour (Hull, Turret roof)
- Cast homogeneous armour (Turret)
| Armour | Front (Slope angle) | Sides | Rear | Roof |
|---|---|---|---|---|
| Hull | 75 mm (30°) Front plate 50 mm (70°) Front glacis 25 + 50-60 mm (25-70°) Joint plate 60 mm (26-50°) Lower glacis |
60 mm | 60 mm (35-75°) Top 60 mm (2-69°) Bottom |
40 mm Front 30 mm Rear |

Ammunition
The available ammunition allows for engaging all types of targets:
- BR-350A (MD-5 fuze): APHEBC; a shell with high explosive mass that will one-shot any tank it penetrates but has an average penetration power.
- BR-350P: APCR; a composite round with the best penetration but no explosive filler and will only penetrate flat vertical surfaces.
- BR-350SP: APBC; a solid shot with an even better penetration but no explosive filler.
- BR-350B (MD-8 fuze): APHEBC; same shell as the BR-350A but with increased penetration at the cost of slightly less explosive filler.
- OF-350M: HE; useful for destroying open and lightly armoured vehicles.
- Sh-354T: Shrapnel; useful against vehicles that are resistant to the HE shells but too thinly armoured to trigger the fuzes of AP shells.
- D-350A: Smoke; useful to blind enemy vehicles that are too remote for you to disable so that you can progress towards objectives.

The small calibre of the DT machine gun makes it largely ineffective against all armoured vehicles but the ones with an open compartment. It still can be used to ping targets as a rangefinding help or to mow down minor obstacles blocking your line of sight.
Usage in battles
When playing the KV-1S, remember that you are still a heavy tank. Keep your front armour facing your enemies at all times, and preferably angled (but slightly less than KV-1 (L-11)). The turret is more durable and can deflect more shots than before, so if possible expose your turret only. Gun has no special penetration value, so try to target weak spots or areas with the least armour. Flanking attacks could end in a fiery demise. Also, this tank is still a KV-1 in its heart.
The best tactics for this tank is: keep a low profile and stay behind the main assault. When your team has advanced to the enemy's base, the KV-1s is best used to round up straggling enemy tanks behind your lines. If these tanks aren't destroyed, they'll attack your team's rear.
The common enemies are armed with guns that usually can penetrate the driver's hatch. Watch out for enemy T-34 (especially mod. 1941 and 1942, sometimes mods 1943 and the 57 variants), since they can flank you easily. Also, watch out for all German Pz.IV & StuG armed with long 7.5 cm gun, as it can penetrate your front armour even if you are angled.
This vehicle (due to its higher BR) can also meet many opponents that your armor has no chance of stopping, avoid direct confrontation with them. (Includes: T-34-85, SU-85, Dicker Max & Nashorn, Sherman Firefly & Achilles)
Meeting other KV-1's and Churchill may become a stalemate as the KV-1S gun may not penetrate against their formidable armour. This leads to the hope that the APCR ammunition works, and the firing of several rounds into the target for penetration.
Pros and cons
Pros:
- Faster than its predecessor and successor, yet frontal armor is the same
- Very hard to knock out in one shot
- Adequate gun
- Bouncy turret front
- Wide tracks make for good cross-country performance
- Resilient. Can remain reasonably effective, even with a lot of damage
- Very effective overall
Cons:
- Side armour is considerably weaker (75 mm into 60 mm)
- Turret is cramped
- Very low reverse speed, poor low-speed handling
- Vulnerable to the long-barreled 75mm gun of the StuG III and Pz.IV F2,G, H and J
- First reverse gear presents a slow reverse speed of around -5 kph.
- Still carries most of the flaws of the KV-1 L-11
- Still a heavy vehicle, poor acceleration.
- Still cannot move on pace with T-34s
- Gun lacks penetration against heavier opponents: The KV-1 ZiS-5 and both Churchills are very hard to get through. APCR is unreliable.
History
During operation Barbarossa, the KV-1 (Family) of tanks had gained weight in armor due to the increased need for armor. Due to this the KV-1S tank was designed. Major changes included:
- a new planetary gear transmission improving reliability and allowing the use of regenerative steering
- a new lower profile cast steel turret with a commanders cupola
These changes did bring in to question the usefulness of the tank due to the reduced weight necessitating a reduction in the armor thickness making more akin to the T-34 (Family) [1]
