The BM-21 is a Soviet truck mounted 122mm multiple rocket launcher, the "Grad" stands for hail! A minimum range of 1.6km and a maximum of up to 40km and is the most widely used multiple rocket launch system in the world!
3 resin BM-21 from Battlefront, not too difficult to put together, 2 for the Russians/East Europeans and 1 for my North Koreans! Yet again probably scenery or an objective?
15mm Oddzial Osmy and Khurasan miniatures for a touch of scale..........
