BMD-4
The BMD-4 (Russian: "Боевая Машина Десанта-4"; Boyevaya Mashina Desanta-4 literally "Combat Vehicle of the Airborne") is an amphibious infantry fighting vehicle (IFV) originating from post-Cold War Russia. Originally designated as the BMD-3M, the chassis of the BMD-4 is the same as that of the BMD-3, because it was developed on the same basis. This armored fighting vehicle is one of the lightest and one of the most heavily armed in its class, possessing a substantial amount of firepower in comparison to its counterparts. The vehicle was designed to transport Russian Airborne Troops (VDV); increasing its mobility, armament, and protection on the battlefield.
Many components of the vehicle, such as the ergonomics and positioning of the passengers, remain relatively unchanged. Primary differences between the BMD-4 and its predecessors lie in its armament. The vehicle is fitted with the Bakhcha-U turret which consists of: a 100 mm 2A70 low-pressure rifled gun, a 30 mm 2A72 coaxial autocannon, and a 7.62 mm PKT coaxial machine gun. The 2A70 rifled cannon is capable of firing high explosive fragmentation rounds and laser guided anti-tank missiles. It also features secondary weapons designed to engage and destroy enemy infantry and armored fighting vehicles. The automated fire control system of the vehicle is advanced with new features that simplify the use of the vehicle's armament by the gunner and commander.
BMD-3
The BMD-3 (Boyevaya Mashina Desanta, Russian "Боевая Машина Десанта", literally "Combat Vehicle of the Airborne") is an infantry fighting vehicle (IFV) originating from the former Soviet Union. This armored fighting vehicle is one of the lightest in its class and is intended to be a fire support platform for use by airborne and air assault units. The primary armament is a 30 mm 2A42 autocannon capable of firing different types of ammunition which include high-explosive and armor-piecing. The BMD-3 possesses multiple secondary weapons such as the 9M113 Konkurs missile and the AGS-17 grenade launcher to defeat a wide range of targets from enemy infantry to other armored fighting vehicles.
Designed in the 1980s, the vehicle was manufactured by the Volgograd tractor factory under the industrial index Object 950. The BMD-3 entered service with the VDV in 1990 with only 137 vehicles being produced due to the economic depression. The operators of the BMD-3 are Angola and Russia. As of 2013, 123 BMD-3s and 60 BMD-4s are in service with the Russian Airborne Troops.
BMD-2
The BMD-2 is a Soviet airborne infantry fighting vehicle, introduced in 1985. It is a variant of BMD-1 with a new turret and some changes done to the hull. BMD stands for Boyevaya Mashina Desanta (Боевая Машина Десанта, literally "Airborne Combat Vehicle"). It was developed as a replacement of BMD-1 but it failed to replace it completely because of a downfall of Soviet economy in 1980s. NATO gave it the designation BMD M1981/1.
Development
When the Soviet war in Afghanistan broke out the Soviet forces operated BMP-1 IFVs and BMD-1 airborne IFVs. They were both armed with 73 mm 2A28 "Grom" low pressure smoothbore short-recoil semi-automatic gun, 9S428 ATGM launcher capable of firing 9M14 "Malyutka" (NATO: AT-3A Sagger A), 9M14M "Malyutka-M" (NATO: AT-3B Sagger B) and 9M14P "Malyutka-P" (NATO: AT-3C Sagger C) ATGMs and 7.62 mm PKT coaxial tank machine gun. Although their armament made for strong anti-tank firepower, it didn't provide sufficient firepower against enemy unarmored vehicles, infantry, firing points and light fortified positions, especially during mountain battles because of low elevation angle of the main gun.
