Russian forces, who have reportedly suffered considerable losses on the front line, have now deployed additional units of the world’s most powerful mortar, which is capable of using a nuclear warhead on the battlefield…Dubbed the “Sledgehammer,” the self-propelled 2S4 Tyulpan mortar, known as the Tulip in English, has a 240mm cannon — twice the caliber of NATO mortars, which are just 120mm — making it by far the largest caliber mortar system in the world. Carried on its own tracks, it has a range of 19 kilometers and is used to destroy large fortifications, military equipment, or strategic positions.
