The Tiger II is a German heavy tank of the Second World War. The final official German designation was Panzerkampfwagen Tiger Ausf. B,[notes 1] often shortened to Tiger B.[8] The ordnance inventory designation was Sd.Kfz. 182.[8] (Sd.Kfz. 267 and 268 for command vehicles). It was known as King Tiger by Allied soldiers, and is also known under the informal name Königstiger[8] (the German name for the Bengal tiger which translates literally as Royal Tiger).[9][10] The name Königstiger was never used in contemporary German documentation, but was used extensively after the war.
