The Kalmyk Kavallerie Korps started its existence as the Abwehrtruppe 103 (or 103rd Defense Troop), although it was later nicknamed the "Kalmyken Verband Dr Doll" in honor of one Dr. Doll, counter-intelligence officer who was responsile for expanding and divided the unit into two brigades of two regiments each in August, 1942.
The Korps was set-up by the Panzer Army high command within the 6th Army at Stalingrad as a vanguard for the protection of the extended rear lines.
By mid 1943, there were seven reported Kalmyk units in service.(Cavalry of World War II by J Piekalkiewicz)
August 1943 Order of Battle:
Each consisting of 5 squadrons, with 5 additional squadrons fighting in the steppes.
The participation of the Kalmyk Kavallerie Korps in the German Wehrmacht was unique. In make-up and function it resembled a free corp.
Because of its special status, the Kalmyk cavalrymen did not regard themselves as reenforcements of the German Army but rather as an independent allied force.
Germans within the Korp had no jurisdiction but, rather, filled only administrative positions (sanitary services and functions).
The leadership of battalions and squadrons was in the hands of the Kalmyks themselves.
Most officers came from the Red Army Cavalry, meaning that they had senior people who had graduated from the Soviet War Academy.
