During the Civil War, Fedorenko had charge of Red armored trains. He then graduated from the Kharkov Higher Artillery School and the Frunze Military Academy and commanded a tank regiment in 1934. He next commanded the 15th Mechanized Brigade. Fedorenko had charge of armor formations in the Kiev Military District from 1937 to 1940 before becoming chief of the Main Armored Directorate in Moscow in June 1940. During that period, production increased of the new T-34 medium tank and the KV-1 heavy tank.
Following the June 1941 German invasion of the Soviet Union, Fedorenko took charge of Soviet armored and mechanized troops and was deputy commissar of defense. He showed great understanding of armored warfare, in 1942 creating the first Soviet tank armies for deep-penetration operations. In August 1944, he and Pavel Rotmistrov became the only Soviet marshals of armored troops. Fedorenko held his posts until his death in Moscow on 26 March 1947.
