Katjuscha II

The BM-31, introduced from 1944, replaced the comparatively light rockets of the BM-13 with much heavier 30 cm projectiles — nicknamed 'Andryusha' — carrying a considerably larger explosive charge per hit, though with fewer rails and shorter range. It was used specifically to destroy fortified positions and building complexes, where the raw explosive power of individual hits mattered more than the area spread of its predecessor. In the game it hits substantially harder than the BM-13 and strikes from a greater distance, with unchanged vulnerability at close range.
