2S3M
Contents
Description
The 2S3M is a rank IV Soviet tank destroyer with a battle rating of 6.3 (AB/RB/SB). It was introduced in Update "Winged Lions".
General info
Survivability and armour
The survivability of the 2S3M is extremely situational. Due to having absolutely no effective armour to stop any munition but small firearms such as 7.62mm machine guns, it is very vulnerable to all damage. However, solid shots such as APCR, AP or APDS have a chance to go right through the armour without causing any damage whatsoever. The armour of the 2S3M can also partially stop artillery strikes fragmentation depending on the distance between the explosion and the platform. The best armour of the 2S3M is not to be seen. As a howitzer with a very potent weapon, it should be never stay stationary after firing, as this can disclose the location of the platform and be killed.
Armour type:
| Armour | Front (Slope angle) | Sides | Rear | Roof |
|---|---|---|---|---|
| Hull | 15 mm (74°) | 15 mm Top 15 mm Bottom |
15 mm | 10 - 15 mm |
| Turret | 10 - 30 mm Turret front 20 mm Gun mantlet |
15 mm | 15 mm | 10 - 15 mm |
| Cupola | 10 mm | 10 mm | 10 mm | 5 mm |
Notes: -The engine in the front of the hull can occasionally absorb some shots, allowing the 2S3M to fire back and disable the enemy.
Mobility
The 2S3M ,while not the fastest tank at its Battle Rating, is quite speedy and able to get to key positions before most of the enemy. It takes time to accelerate and brake due to the heavy weight of the main gun, but it reaches the top speed fairly easily. It holds a max speed of 60 km/h, which is fast for a tank at this battle rating, and it often reaches its top speed. As it is based on the SU-100P hull, it has a very decent turn rate and reverse speed, being able to reach up to -14 km/h while on reverse. It has a very capable cross-country capability and when track module is researched, along with a much better turn radius.

Armaments
Main armament
The 2S3M has access to the 152 mm 2A33 howitzer, a very potent gun with a significant firepower at the cost of a long reload time. The performance of the gun is excellent, with a shell that has one of the highest amount of explosives at its rank. While it is slower in performance compared to the Type 75 SPH or the Bkan 1C, only going 655m/s compared to the Bandkanon's 850m/s and the Type 75's 750m/s , it holds one of the most devastating rounds in game: the 3OF25. Holding more than 10 kg of TNT equivalent explosive mass, it is able to annihilate any lightly armoured ground vehicle with a direct hit anywhere and even the most protected vehicles can still be destroyed in one shot if aimed properly.
Additionally, the 2S3M also has the 3OF25 (PF) shell. This is a proximity fuse high-explosive shell which detonates automatically when it gets close to any vehicle, rock, or other map obstruction. Before the "La Royale" update, this shell only detonated when it got close to a tank or plane, which allowed it to explode above the roof of an enemy vehicle, destroying it in a similar fashion to a Top Attack Missile. However, with the change of all proximity shells in the new update, it now detonates on any features of the map, be that a rock, a mound of dirt, or even the ground. This, combined with its increased trigger radius(from 1 to 3 meters) makes it less effective for shooting down vehicles hiding just behind ridge lines or obstacles, but more effective against planes. The proximity fuse arms past 300 m, against closer targets the fuse doesn't work and the shell will perform just like the standard 3OF25 shell.
Against planes, the 2S3M is also equipped with a 7.62mm machine gun, which is not very effective against any planes directly. It serves more to attract a plane's attention and secure an easy kill against it with the proximity shell, rather than being used as a killing weapon itself.

Notes:
- The 2S3M uses two-piece ammunition, composed of projectiles (yellow) and propellant charges (orange). Both have separate racks.
- Projectiles and propellant charges are modeled individually and disappear after having been shot or loaded.
- Hull empty: 13 (+33) shells.

Usage in battles
The 2S3M should be used as a support gun, able to take down even the heaviest of targets with a single shot. Teammates should be supported with the power of this weapon as well as the variety of projectiles available to it. It is not to be played as a frontline vehicle due to the immense reload time and aiming of the weapon. However it is a very good guerilla combatant and skirmisher if used as a backup for frontline vehicles.
Pros and cons
Pros:
- Powerful HE shells can finish off anything with overpressure, like Panther II, Tiger II (H), M4A3E2 (76) W, etc.
- HEAT with a penetration of 250 mm is able to penetrate most tanks at the rank
- Has a variety of shell types to suit different preferences and situations: HE, HEAT, HE-VT, APHEBC
- HE-VT shell lets it take an anti-aircraft role and potentially harm lightly-armoured enemies behind cover
- Is turreted, allowing more flexible tactics
- -14 km/h reverse speed is good enough to retreat into cover
- Has a dozer blade to build a dirt cover
Cons:
- Thin armour, any weapon larger than a MG is threatening
- Poor -4° gun depression limits its ability in hilly terrains
- Long reload time
- Turret is huge with ready rack at the back, easy to get spotted and destroy with ammo rack detonation
- Slow turret steering speed
History
By 1964, NATO was equipped with the M109 self-propelled artillery. However, the Soviet army were still using artillery developed during WWII. During an exercise at Yavoriv military base, senior officials determined that the various types of artillery developed during World War II were not suitable for the war at that time. In order to make up for the technological gap with NATO countries, Resolution No. 609-201, issued by the Central Committee of the Council of Ministers of the Soviet Union on July 4, 1965, was finalized, starting the development plan for the new 152 mm self-propelled gun. In 1971, the Soviet Union passed the acceptance of the 2S3 self-propelled gun and began mass production.
