القيادة العليا للجيوش الألمانية
On 1 May 1944, German Army High Command, Oberkommando des Heeres (OKH) issued an order to formally change the panzerjäger's name from "Ferdinand" to "Elefant". This order forbade future use of "Ferdinand" and even directed units in the field to edit their records. This is contrary to popular belief that the name change was linked to the January–April mechanical upgrades to the "Ferdinand" panzerjäger; the name change was purely administrative in nature.
