‘Standard’ BMP-2s destroyed in combat.
The BMP-2 was first born during the ‘Cold War’, developed from the BMP-1 during the late 1970s, going into service in 1980. It, along with the even older BMP-1, stays in service with never ending upgrades.
Russian forces trying out their new BMP-2M, somewhere in Belarus, December 2022.
The modern all-inclusive upgrades (armor, armament, power-pack, etc) for the BMP-2 are referred to, in Russian, as berezhok (бережок), and were first revealed at the end of 2019.
By August 2021, the first BMP-2Ms entered service, with the Western Military District, Leningrad Region.
‘M’ series upgrades for weapons & targeting systems, on public display.
In addition to the BMP-2M’s 30-milimeter(mm) 2A42 gun, a long barreled 30mm AGS-17 (Avtomaticheskiy Granatomot Stankovyy, automatic grenade launcher), 7.62mm machine guns and four launchers for the 9M133 anti-tank ‘Kornet’ missiles, the targeting system is using second generation thermal sights for the gunner, and the TC (tank commander) now has a panoramic sight.
BMP-2M without the armor upgrade, supposedly in the Northern Military District, sometime in 2023.
Also, the power-pack (motor/transmission) now uses a more powerful turbocharged diesel motor, and don’t forget the extra armor protection.
Armor upgrade being made in the field.
This ‘standard’ BMP-2 is being upgraded in the field with the newest armor protection.
At least it is getting the ‘M’ series armor?
In this video report, published on 20DEC2024, reporter Alexander Stroganov goes for a ride in the latest berezhok/upgrade:
Surprise! This BMP-2M berezhok turret is mounted on a BMP-3 hull.
How about on a BTR-90?
