Heeresgruppe F
Throughout 1943-44, the 2nd Panzer Army was progressively stripped of its heavy armor destined for the war on the Eastern Front, and became a primarily motorized infantry force. It did gain specialized Alpine support from units like the Brandenburgers and 7th SS Volunteer Mountain Division Prinz Eugen divisions. However, endemic guerilla warfare cost the 2nd Panzer Army heavily, and only months after the Raid on Drvar (Operation Rösselsprung) failed to assassinate the communist partisan leadership via airborne assault, the 2nd Panzer Army and all of Army Group F were pushed out of Belgrade in a joint operation by the Partisans and Red Army during the Belgrade Offensive. The 2nd Panzer Army finished the war in disarray in modern Austria.
