BIG BOYZ TOYZ TECH SPECS Design Externally the BRDM-2 was designed with a box-like hull and boat-like bow to improve its amphibious capabilities. It was designed with a crew of four in mind (a driver, co-driver, commander and gunner). There are two pairs of chain-driven belly wheels which allowed trench crossing when lowered by the driver. An early centralised tyre pressure regulation system was also fitted to help when crossing various types of terrain. This can be used to adjust the tyre pressures in all four tires at once or individually to suit the terrain as required. The engine (a GAZ-41, 140hp V8 petrol) is situated at the rear and separated from the crew compartment by an armoured barrier. An NBC filter system was fitted too. The armour on the vehicle itself is composed of welded steel, with a maximum thickness of 14mm, that protects fully from small arm fire and small shell fragments. However it cannot withstand hits from .50 calibre rounds or larger armaments. As with all wheeled vehicles of this vintage the tyres are not protected and, while vulnerable to punctures from small arms fire, the tyre pressure regulation system could keep a tyre inflated for up to a maximum of seven rounds! There is also a winch mounted internally with a 30m cable and a four-tonne capacity. This winch was designed for use for self-recovery when stuck in difficult terrain. The engine also supplies power to a circular water jet, which is equipped with a four-bladed propeller at the rear of the hull. This is covered by an armoured shutter while on land which needs to be removed before entering the water (and doubles up as extra frontal protection when on land). The water jet allowed a speed of 10km/h for up to 19 hours. There is a trim-board stowed under the nose of the hull which again has to be erected before entering the water. For the driver and commander, who are both seated at the front of the crew compartment, a (supposedly) bulletproof windscreen was provided for protection. There are two armoured shutters which could be lowered over the windscreen when going into combat. When in the open position these shutters also protected them from being blinded by sunlight, snow or rain. For more surround vision they could use their periscopes, which could also be swapped out for night vision scopes when required. To that end, the BRDM-2 is also fitted with an IR (infrared) spotlight and four IR driving lights. The turret (BPU-1) was originally designed for the BRDM-2, but this design was also widely used in other later Soviet vehicles. It is unusual in its design as there is no top hatch. The turret allowed the two weapons systems (a 14.5mm KPVT heavy machine gun and a coaxial mounted 7.62mm PKT) to elevate between -5 to +30 degrees. F
