Heavy artillery
Both World War I and World War II witnessed the use of extremely heavy artillery. Launching massive warheads over great distances was useful for damaging and demoralising the enemy.
Germany used these pieces most extensively, such as at Leningrad, and in the construction of the Atlantic Wall along the western coast of Europe. But this weaponry was often impractical, especially when Blitzkrieg tactics could capture areas before the guns could be brought into action.
This super-artillery was, however, used to devastating effect on several occasions, particularly the siege of Sevastopol, which suffered heavily from the Dora (a railway gun).
