Armeeoberkommando in the context of "Oberkommando des Heeres"

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 Common Army (German: Gemeinsame Armee, Hungarian: Közös Hadsereg), as it was officially designated by the Imperial and Royal Military Administration, was the largest part of the Austro-Hungarian land forces from 1867 to 1914, the other two elements being the Imperial-Royal Landwehr (of Austria) and the Royal Hungarian Honvéd. However, it was simply known as the Army (Heer) by the Emperor and in peacetime laws, and, after 1918, colloquially called the k.u.k. Armee (short for Imperial and Royal Army).

Established on 15 March 1867 and effectively disbanded on 31 October 1918 when its Hungarian troops left, the Common Army formed the main element of the "armed power" (Bewaffneten Macht or Wehrmacht) of the new dual monarchy, to which the Imperial and Royal Navy (k.u.k. Kriegsmarine) also belonged. In the First World War all land and sea forces of the monarchy were subordinated to the Armeeoberkommando set up in 1914.
