The BM-21 "Grad" (Russian: БМ-21 "Град"), is a Soviet truck-mounted 122 mm multiple rocket launcher,[1] and a M-21OF rocket[2] were developed in the early 1960s. BM stands for boyevaya mashina (combat vehicle), and the nickname grad means "hail". The complete system with the BM-21 launch vehicle and the M-21OF rocket is designated as the M-21 field rocket system. The complete system is more commonly known as a Grad multiple rocket launcher system. In NATO countries, the system (either the complete system or the launch vehicle only) was initially known as M1964. Several other countries have copied it or developed similar systems.
I'm pretty sure that you can't just rip info from Wikipedia, so no verbatim. Just re-word it and you'll be fine.
