2S4 Tyulpan

The 2S4 Tyulpan is a Soviet 240 mm self-propelled heavy mortar built around a large breech-loaded 2B8 mortar on a tracked chassis. Its unusually heavy bombs and low rate of fire make it a siege and bunker-attack weapon rather than a conventional rapid-fire howitzer, and Russian forces have used or lost examples in Ukraine where its size and firing signature make it a high-value counter-battery target.
