Katyusha
"On the Fuhrer's birthday, a barrage of Katyusha rockets will tear Berlin to pieces! With your bullets... with your bayonets... with your bare hands. Do the same to their wretched soldiers!"

The BM-series of rocket artillery, nicknamed Katyusha by the Red Army's cannon fodder, is the Soviet response to the German Nebel- and Panzerwerfers (German for:"(it) werfs nebels"). Katyusha refers to the firing system that fired the rockets themselves, with the Soviets placing them on whatever vehicle they had at the time. Because of this, there were as many variants to the system as there were mounts and warheads, and the Soviets tended to use them en masse to devastating effect, as seen in their very first deployment, were the rockets were used on concentrated Germans who were entrenched in a Russian village.
The Soviets loved the Katyusha so much, that not only does it continue to be a symbol for the Red Army during the War, but they continued to develop the MRLS technology up to the present-day. Rumors that they used German Rocket Scientists to further their tech is HERESY.
