Azerbaijan's BRDM-2 Upgrade: ZKDM

Azerbaijan gives the venerable BRDM-2 a new breath:


BRDM-2 "Boyevaya Razvedyvatelnaya Dozornaya Mashina" when introduced in 1962, became the prime armored reconnaissance vehicle of Soviets and their allies namely the Warsaw Pact. It was also largely exported to more than 45 countries world wide.


BRDM-2 is a 7 ton 4x4 vehicle of welded steel contruction. The vehicle has a crew of 4 and a V8 gasoline engine located in the rear.

The crew enters and exits the vehicle thru the hatches above the driver and commander seats in the front of the vehicle.

The vehicle has 4 small chain driven wheels along the middle of the hull sides that can be raised and lowered to allow better traction and to lower the ground pressure on soft terrain.

A one man turret composes the fire power of the BRDM2. The turret is armed with 14.5mm KPVT heavy machinegun and a coaxial 7.62mm PKT machinegun.
