Terminological Notes:
Strictly speaking the term '\'Deutsches Afrika Korps refers only to the corps headquarters and its attached units, though amateur writers often carelessly use the name in reference to all the German units in North Africa before the retreat to Tunisia. The most notable of those other units were the Afrika zbV ("special purpose") Division, which was created as an infantry division and slowly upgraded to a fully motorized division, and then redesignated as the 90th Light Division; the 164th Light Afrika Division, also an infantry division; and the Ramcke parachute brigade (named after its commander). There were also eight Italian divisions under Rommel's command in Panzer Army Afrika'', including two armored divisions with very inferior equipment, two motorized divisions, three infantry divisions, and one parachute division. The army was supported by a number of smaller units from both the German and Italian armed forces.
The designation Light (G. leichte) did not refer to a standardized table of organization and equipment (TOE) for the various German divisions that bore that designation. For instance, the 5th Light Division had an organization very similar to the 21st Panzer Division, whereas the
164th Light Afrika Division was at first a partially motorized infantry division and never had any tanks at all. Various German divisions in Africa occasionally reorganized or re-equipped without a change of name, or conversely were redesignated with a new name without any substantial reorganization.
Historical Postscript:
After the surrender in Africa three of the German divisions that had fought in the Western Desert were reconstituted in western Europe. The 15th Panzer Division was reformed as a Panzergrenadier division, and renumbered as the 115th since there was already a 15th Panzergrenadier Division on the books. The 21st Panzer Division was reformed under its own name. The 90th Light Division was reformed as the 90th Panzergrenadier Division.
