"Using the original BMP-1 chassis the Russians added an upgraded but outdated electronic warfare jamming system, additional radios for command and control, antennae and the radar surveillance and jamming dish located in the rear part of the turret. This tracked EW platform is capable of jamming enemy radar and FM communications within LOS (line of sight). It has a 30 mm gun, laser rangefinder, and 10 km maximum range for the radar."
