For years now the SSU has made its own that the artillery was the most important weapon on a modern battlefield. Fielding huge guns since the beginning of the war has been a successful tactic for the Soviets: no reason to stop now. Second variant mounted on the heavy IS-5 chassis, the VLADIMIR LENIN can deliver death more than 10 kilometers away with its 252 mm field mortar, though at a slow pace. Reloading the weapon is difficult in a closed space, even inside this huge tank. Even if quite ponderous the LENIN moves fast enough so no counter battery fire can ever catch him. When the big guns of the other side fire, the LENIN has been long gone.
