The BMP-2M is an upgrade of existing BMP-2 mechanized infantry combat vehicles. The upgrade consists of fitting the Berezhok weapon system, which is a deep modernization of the BMP-2 turret. The main and coaxial armament are retained and complemented with the Kornet anti-tank missile system and an automatic grenade launcher. Furthermore, the commander is provided by a pedestal mounted panoramic sight. This improves situational awareness and target acquisition significantly. Russia planned to upgrade its BMP-2s for a long time, but often postponed this effort. The first BMP-2M seem to have entered active service in Russia around 2020.
