The BM-13, and its derivatives the smaller BM-8 and larger BM-30 were mounted on a wide variety of trucks and in a wide variety sizes. Initially, ZiS-5 and ZiS-6 trucks were favoured, but the BM-13 design was soon standardised onto the newly available Lend-Lease Studebaker US6. Our Katyusha and Studebaker were made by Toddel.
