The BM-21 Grad is a Soviet truck-mounted 122-mm multiple rocket launcher, developed in the early 1960s. The development of the 122 mm BM-21 Grad divisional-level RSZO took place in the mid-1950s under the guidance of the Splav Scientific Production Concern at Tula.
The BM-21 122 mm multiple rocket launcher (MRL) system entered into service with the Soviet Army in 1963 to replace the aging 140 mm BM-14 system. The main role of the BM-21 Grad system is to support the division with suppressive fire to counter anti-tank missile, artillery and mortar positions, destroy strong points and eliminate enemy nodes of resistance on the immediate battlefield.
