The BM-14 can fire 140mm M-14 rockets with a high-explosive fragmentation warhead, a smoke warhead or a chemical warhead. It is similar to the BM-13 “Katyusha” and was partly replaced in service by the 122mm BM-21 Grad.
Launchers were built in 16 and 17-round variants. The rockets have a maximum range of 9.8 kilometers (6.1 mi).
The weapon is not accurate as there is no guidance system, but it is extremely effective in saturation fire.
