The vehicle is intended to perform tactical reconnaissance, combat and guard security tasks, and fight reconnaissance/subversive groups. As a rule, it serves as part of reconnaissance detachments and patrols acting on flanks and in front of friendly troops, as well as in the enemy's rear up to 80 - 100 km. The BRM-3K is based on the BMP-3 infantry combat vehicle, has an identical hull and turret welded from steel armor plates and retains similar maneuverability, cross-country capability, survivability, and reliability. The vehicle boasts a large number of information-search devices. A set of reconnaissance devices mounted on the vehicle enables the crew to seek for, detect and designate targets at any time of day and year in poor visibility (rain, snow, fog, smoke screens and blind effects generated by light sources), process and transmit received reconnaissance information to reception posts deployed about 100 km away and, if need be, at 350 km.
