The BRDM-2 (Boyevaya Razvedyvatelnaya Dozornaya Mashina, Боевая Разведывательная Дозорная Машина, literally "Combat Reconnaissance/Patrol Vehicle") is an amphibious armoured scout car used by states that were part of the Soviet Union and its allies. It was also known under the designations BTR-40PB, BTR-40P-2 and GAZ 41-08. This vehicle, like many other Soviet designs, has been exported extensively and is in use in at least 38 countries. It was intended to replace the older BRDM-1, and has improved amphibious capabilities and better armament compared to its predecessor. History After a few years of use by the Soviet Army, the limitations and drawbacks of the BRDM-1 became obvious. The vehicle had no turret and to operate the armament the gunner had to open a hatch and expose himself to enemy fire. The vehicle was not fitted with an NBC protection system, and had no night vision equipment by default. The vehicle also lacked any kind of special sights, which undermined its function as a reconnaissance vehicle. These drawbacks encouraged the design team to create a new vehicle which would suit the modern battlefield. Construction The BRDM-2 has a crew of four: a driver, a co-driver, a commander, and a gunner. It has two pairs of chain-driven belly wheels lowered by the driver, which allow trench crossing just like its predecessor, and a centralized tire pressure regulation system, which can be used to adjust the tire pressure of all four tires or individual tires while the vehicle is in motion to suit to the ground conditions. Externally, it differs from the BRDM-1 by having a larger, box-like hull. It retains the boat-like bow of the BRDM-1. However, the crew compartment is now further forward and the new GAZ-41 gasoline V8 engine is in the rear. Thanks to this, the engine is much better protected from enemy fire. The engine compartment is also separated from the crew compartment by an armoured barrier. The driver's and commander's stations are in the front of the vehicle, with the driver positioned on the left and commander on the right. Both of them sit behind a bulletproof windscreen, which provides them with their primary view of the battlefield. When in combat, the windscreen can be additionally protected by twin armoured shutters. When the shutters are in their opened position, they protect the driver and commander from being blinded by the sunlight and ensure that the windscreen won't be blurred
