The Knight's Cross of the Iron Cross and its variants were the highest awards in the military and paramilitary forces of Nazi Germany during World War II. The decoration was awarded for a wide range of reasons and across all ranks, from a senior commander for skilled leadership of his troops in battle to a low-ranking soldier for a single act of extreme gallantry. A total of 7,321 awards were made between its first presentation on 30 September 1939 and its last bestowal on 17 June 1945. This number is based on the acceptance by the Association of Knight's Cross Recipients (AKCR). Presentations were made to members of the three military branches of the Wehrmacht—the Heer (Army), Kriegsmarine (Navy) and Luftwaffe —as well as the Waffen-SS, the Reich Labour Service, and the Volkssturm. There were also 43 foreign recipients of the award.
