NotesThe Sturmmörser was a heavy 380mm Raketen Werfer which could fire a 376 kg round up 6000m. It was mounted on the chassis of the Tiger I heavy tank and the main weapon was housed in an armoured citadel. The number of rounds was limited to fourteen max. It also carried one MG34 for local defense. It was used to smash fortifications and could penetrate 2.5m of concrete. It was issued to armoured assault mortar companies and served in on both the eastern and western front.
