The Panther is a German medium tank deployed during World War II on the Eastern and Western Fronts in Europe from mid-1943 to the war's end in 1945. It had the ordnance inventory designation of Sd.Kfz. 171. It was designated as the Panzerkampfwagen V Panther until 27 February 1944, when Hitler ordered that the Roman numeral "V" be deleted. The naming of Panther production variants did not, unlike most German tanks, follow alphabetical order: the initial variant, Panther "D" (Ausf. D), was followed by "A" and "G" variants.
