The BM-21 MT STRIGA is a forty-tube, multi-launch, self-propelled rocket artillery system with a loading device, which is used to provide covering fire support for troops, firing unitary high-explosive fragmentation rocket projectiles at larger area targets. The rocket launcher can fire both single rounds and volleys from the cabin or use a portable device from a nearby trench at max. length 60 m. The basic type of fire is indirect fire. If a combat operation requires direct fire with elevation from 0° to 10° it can only be done within the range determined by elevation and traverse sensors.
