The military districts, also known in some English-language publications by their German name as Wehrkreise (singular: Wehrkreis),[1]: 27–40 were administrative territorial units in Nazi Germany before and during World War II. The task of military districts was the organization and the handling of reinforcements and resupplies for local military units. The Replacement Army (Ersatzheer) managed the districts. Responsibilities such as training, conscription, supply, and equipment were (at least partially) entrusted to the Ersatzheer.[2]: B2
