As the number of German troops committed to the North African Campaign of World War II grew from the initial commitment of a small corps, the Germans developed a more elaborate command structure and placed the enlarged Afrika Korps, with Italian units under this new Italian and German command and a succession of commands were created to manage Axis forces in Africa:
When the German: Afrika Korps was formed on 11 January 1941 it was subordinated to the Italian chain of command in Africa. In the middle of 1941 Oberkommando der Wehrmacht (OKW, Armed Forces High Command) created a larger command structure in Africa, forming a new headquarters, Panzer Group Africa (German: Panzergruppe Afrika, Italian: Gruppo Corazzato Africa). On 15 August 1941, Panzer Group Africa was activated with newly promoted German: [[General der Panzertruppe]] Erwin Rommel in command. The Panzer Group controlled the German: Afrika Korps and other units that were sent to Africa (notably the 90th Light Infantry Division), and the Italian X Corps and XX Corps.
Panzer Group Africa was renamed Panzer Army Africa (German: Panzerarmee Afrika, Italian: Armata Corazzata Africa) on 30 January 1942. (A German Panzer group was an army-level headquarters. As the war progressed all of the Panzer groups were renamed Panzer Armies.)
Panzer Army Africa was renamed German-Italian Panzer Army (German: Deutsch-Italienische Panzerarmee, Italian: Armata Corazzata Italo-Tedesca) in October 1942 during the long retreat after the defeat at the Second Battle of El Alamein during the Western Desert Campaign.
In February 1943, the headquarters was expanded and called Army Group Africa (German: Heeresgruppe Afrika, Italian: Gruppo d'Armate Africa) to manage the defence of Tunisia during the final stages of the North African Campaign. Army Group Africa included the German Fifth Panzer Army (German: 5. Panzerarmee) and the Italian 1st Army. Command of the Army Group was turned over from Rommel to Hans-Jürgen von Arnim in March. He surrendered the Army Group on 13 May 1943, ending the Axis presence in Africa.
Throughout its existence, this headquarters controlled the Afrika Korps and for most of its life it controlled a number of other German and Italian units as well. Not all German units in Africa subordinate to the Afrika Korps; some were reserves for the Panzer Army and some were occasionally subordinated to Italian armies or corps. The following overview of its components is taken from lexikon-der-wehrmacht de, with dates corrected (see references).
