The heavy Gustav was the largest piece of artillery ever to be utilized in combat. Its most prominent feature was the 100 ft long cannon with an insane caliber of 31.1 inches. The barrel was rifled, firing an approximately 4,500 lb shell measuring 11 ft in length, and around 2 feet wide. Each shell could blast craters that could swallow buildings, the diameter measuring around 39ft wide, and 39 feet deep. (ps MUNITIONEN is the German word for munition, zoom in on the railcars)
