The Truppenamt was the cover organisation for the German General Staff from 1919 through until 1935 when the General Staff of the German Army (Heer) was re-created. This subterfuge was deemed necessary in order for Germany to be seen to meet the requirements of the Versailles Treaty. It completely revised German tactical and strategic doctrine and thereby conserved, re-energised, and unified the military thinking and capability of the Reichswehr, later to become the Wehrmacht.

The German General Staff, originally the Prussian General Staff and officially the Great General Staff, was a full-time body at the head of the Prussian Army and later, the German Army, responsible for the continuous study of all aspects of war, and for drawing up and reviewing plans for mobilization or campaign. It existed unofficially from 1806, and was formally established by law in 1814, the first general staff in existence. It was distinguished by the formal selection of its officers by intelligence and proven merit rather than patronage or wealth, and by the exhaustive and rigorously structured training which its staff officers undertook.
