The 11th SS Panzer Army (SS-Panzer-Armeeoberkommando 11) was little more than a paper army formed in February 1945 by Heinrich Himmler while he was commander of Army Group Vistula. (The army was officially listed as the 11th Army but it was also known as SS Panzer-Armeeoberkommando 11 and is often referred to in English sources as the 11th SS Panzer Army.)
Military historian Antony Beevor writes that when the 11th SS Panzer Army was created the available units at best could constitute a corps, but 'panzer army', observed Hans-Georg Eismann, 'has a better ring to it'. It also allowed Himmler to promote SS officers to senior staff and field commands within the formation. Obergruppenführer Felix Steiner was named its commander.
