  • Basic Description :
    • The BMP-2M (SB4-3) is the anti-tank variant, one of two variants offered by the Tula Arms Plant in Tula, Russia. Development for the BMP-2M began in the late-1990’s between the Tula Instrument Engineering Design Bureau and Kurgan Special Design Bureau of Mechanical Engineering developing the first version of the BMP-2M, featuring a new combat module dubbed the ‘Bakhcha-U’, used in the BMP-3 Infantry Fighting Vehicle (IFV). However, due to issues with installation, excess weight of the module which resulted in loss of amphibious capabilities, and overall cost of the program, the Russian Army lost interest in the program. A single prototype was developed, but no production occurred. Later on, another upgrade program developed a different version of the BMP-2M developed by Kurganmashzavod JSC with the KBP Instrument Design Bureau. This version utilized the B05Y01 “Berezhok” combat module which was equipped with 4x Kornet Anti-tank Guided Missiles (ATGM), and a new Fire Control System (FCS) that was equipped with a 3rd-generation thermal imager for the Gunner and a panoramic 3rd-generation thermal imager for the Commander, without much modification to the original BMP-2 hull. This new module significantly boosted the capabilities of the BMP-2M and in 2017, the Russian military contracted KBP with deliveries occurring in 2020. In the mid-2010’s one of the last versions of the BMP-2M was introduced by a team lead by Kurgan specialists in the Tula Arms Plant. This variant was broken into two different models. One specializing in Anti-tank operations with the other specializing in anti-personnel operations. These would be dubbed the BMP-2M (SB4-3) and BMP-2M (SB4-2). Focusing on the BMP-2M (SB4-3), this variant features heavy armor, armament, and electronic modifications to allow it to engage heavy armor with the use of the Ataka-T, a dual ATGM launcher capable of firing variants of the 9M120 anti-tank guided missile. The BMP-2M (SB4-3) utilizes a version of the Sodema FCS found in the BMP-3 which allows it to engage targets during day or night operations thanks to its 3rd-generation thermal imager, illuminator, and integrated laser rangefinder. This FCS allows detection ranges for the BMP-2M up to 5km during the day, while up to 3km during night operations. Not to mention, the FCS also allows for the firing of the Ataka missiles while on the move. In terms of armor protection, the BMP-2M (SB4-3) features the same layout of the standard BMP-2, however it features an addon armor kit known as the 675-sb3KDZ which introduces Polymer NERA armor paneling across the vehicle to protect against large caliber rounds as well as Bar armor to protected against HEAT-shaped charges on both the hull and turret. This kit allows for increased crew survivability at the cost of amphibious capabilities due to the increase in weight. Powering the vehicle is a UTD-23 Supercharged Diesel Engine capable of speeds of 65km/h as well as powering all vital equipment. Overall the BMP-2M (SB4-3) is a significant improvement over the standard BMP-2, however it has yet to be adopted by the Russian Army. The 675-sb3KDZ Armor Kit however has been adopted has has been seen equipped to both standard BMP-2’s as well as the BMP-2M ‘Berezhok’.
    • Note : I will not be creating a suggestion for the BMP-2M (SB4-2), or the anti-personnel version of the BMP-2. If anyone wishes to create one please feel free to use my sources.

  • In-game :
    • The BMP-2M (SB4-3) is a BMP-2 with advanced armor and anti-tank weapons. Equipped with the 675-sb3KDZ Armor Kit, the Ataka-T Launcher, as well as retaining the 2A42 Autocannon with the capability to fire APFSDS-T rounds, the BMP-2M (SB4-3) is a multi-mission platform that can target the latest main battle tanks, light armor, and even helicopters from up to 8km away. This is a very effective infantry fighting vehicle that removes a lot of the weaknesses found in the earlier BMP-2, however it can still be penetrated relatively easy by modern 120mm and 125mm APFSDS-T rounds. This vehicle would make an exceptional addition to Rank VII in the USSR tree however, this vehicle should be added when more varieties of IFV are offered to other country’s in need of high ranking, light armor/IFV’s.
    • Estimated Battle Rating: 10.0.

Isn’t the 675-sb3KDZ Armor Kit a separate piece from this modification?

I think you replied to the wrong person, but from what I can tell the 675-sb3KDZ kit can be equipped to multiple versions. That is to say, it is not mutually exclusive.

Oh my bad. I get those two buttons mixed up 🤦‍♂️
