The survivability of the 2S3M is a very situational one. Due to having absolutely no effective armor to stop any munition but small firearms, it is very vulnerable to all damage. However, solid shots such as APCR have a chance to go right through the armor without making any damage whatsoever. The armor of the 2S3M can also partially stop artillery strikes fragmentation depending on the distance between the explosion and the platform. The best armor 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.

Notes:

Mobility

The 2S3M is not exactl agile, but it is nowhere near being tanky. It takes time to accelerate and brake due to the heavy weight of the main gun but reaches the top speed fairly easily. It holds a max speed of 60 km/h which is fast for a vehicle. 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 13 km/h while on reverse, faster than almost any Russian vehicle seen at the game. It has a very capable country-cross capability and when track module is researched, it is able to hold a much better turn radious compared to any other Russian vehicle in game.

The 2S3M has access to the 2A33 152 mm howitzer, a very potent gun with a significant firepower. It is the only howitzer in game capable of firing HEAT and ACBC rounds. The performance of the gun leaves nothing to expect, decent muzzle velocity for rounds as well as a slow but steady aiming speed. While it is slower in performance compared to the Type 75 SHP or the Bkan 1C, it holds one of the most devastating rounds in game: the 3OF25. Holding more than 10kg of TNT equivalent explosve mass, it is able to annihilate any ground vehicle with almost any hit.

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 skirmmisher if used as a backup for frontline vehicles.

Pros and cons

Pros:

• Its deadly HE shells can finish anything with overpressure, like Panther II, Tiger II (H), M4A3E2 (76) W, etc.
• Has a variety of shell types: HE, HEAT, HE-VT, APHEBC
• 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
• Has NVD for night battles

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, easy to get spotted and hit

History

Describe the history of the creation and combat usage of the vehicle in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).
