B集團軍
In February 1943, Army Group Don and the existing Army Group B were combined and re-designated Army Group South. A new Army Group B became a major formation elsewhere. The German Sixth Army, which was destroyed in the Battle of Stalingrad, was re-constituted and later made part of Army Group South in March 1943. On 4 April 1944, Army Group South was re-designated Army Group North Ukraine. Army Group North Ukraine existed from 4 April to 28 September.
