When Operation Barbarossa stalled outside of Moscow in December 1941 and the Russian counter-attack started, Hitler took direct command of the Army and re-organized the armed forces' command structure. The Office of the Chief of Army Armament and the Reserve Army under "Generaloberst" Friedrich Fromm was created, subordinate to the commander in chief, army (head of the OKH, Hitler). Fromm had enough power at his disposal to control the German state because his position controlled army procurement and production and commanded all army troops inside Germany.
