the Serbian defense firm Yugoimport SPDR. The package adds a turret (from the Yugoslav M-80 APC). It is armed with one 30 mm cannon, one 7.62 mm Zastava M86 machine gun, two ATGM launchers capable of firing 9M14 Malyutka anti-tank guided missiles (ATGM)s and four smoke grenade launchers. South Lebanon BTR-50PK – Converted into an improvised medevac vehicle with a cut down front and a hatch in the front. Ukraine BTR-50PK based ARV. BTR-50M – BTR-50PK upgrade built by Morozow. It features improvements in firepower and mobility, both of which can be carried out independently. Improvements in firepower are achieved by adding one of two new fighting modules (turrets), both of which are armed with one 30 mm ZTM1 or 2A72 autocannon, one 7.62 mm KT or PKT coaxial machine gun, one 9K113 Konkurs (NATO: AT-5 Spandrel) ATGM and one 30 mm AGS-17 automatic grenade launcher. Both main guns are stabilized in the vertical axis (the second variant has a two axis stabilization) and have electro-mechanical aiming drives. Both have a maximum effective range of 4,000 m and can be elevated or depressed between −10° and +60° or −4° and +60°. The vehicle carries 150 rounds (the second variant carries 350 rounds). Both machine guns have a maximum effective range of 1,600 m. The vehicle carries 2,000 rounds in four batches of 500, (the second variant carries the same quantity of ammunition but in two batches of 1,000 rounds). The ATGM system has a minimum range of 100 m and maximum range of 4,000 m with four missiles. The automatic grenade launcher has a maximum range of 1,700 m. The vehicle uses a number of instruments with its armament. These include the TKN-5 day/night sight with a laser rangefinder, the PZU-7 day sight for firing at air and ground targets and the 9Sh119M1 anti-tank guided missile system sight. Mobility is improved by replacing the Soviet-built engine with the UTD-20 6-cylinder 4-stroke V-type water-cooled diesel engine built in Ukraine, replacing the gearbox with a planetary system and installing hydraulic volumetric transmission. The suspension has also been improved by adding three return rollers. The vehicle has a new system of air intakes and exhausts on the left hand side of the front of the engine deck. This upgrade can also be applied to BTR-50PU vehicles. This vehicle has a greater combat capability, lower fuel consumption and a higher power-to-weight ratio. The vehicle
