The Oberkommando des Heeres (lit. 'Upper Command of the Army'; abbreviated OKH) was the high command of the Army of Nazi Germany. It was founded in 1935 as part of Adolf Hitler's rearmament of Germany. OKH was de facto the most important unit within the German war planning until the defeat at Moscow in December 1941.
During World War II, OKH had the responsibility of strategic planning of Armies and Army Groups. The General Staff of the OKH managed operational matters. Each German Army also had an Army High Command (Armeeoberkommando or AOK). The Armed Forces High Command (Oberkommando der Wehrmacht) then took over this function for theatres other than the Eastern front.
The OKH commander held the title of Commander-in-chief of the Army (Oberbefehlshaber des Heeres). After the Battle of Moscow, the OKH commander Field marshal Walther von Brauchitsch was removed from office, and Hitler appointed himself as Commander-in-Chief of the Army.
From 1938, OKH was, together with Oberkommando der Luftwaffe (transl. Air Force High Command) and Oberkommando der Marine (transl. Naval High Command) formally subordinated to the Oberkommando der Wehrmacht.
