Akhlyustin fought in World War I as a cavalryman and joined the Red Army during the Russian Civil War, becoming a junior commander. He held command positions in cavalry units between the wars and commanded a cavalry division in the Soviet invasion of Poland and the Winter War. At the outbreak of Operation Barbarossa, he commanded the 13th Mechanized Corps, destroyed during the Battle of Białystok–Minsk in late June and early July 1941. Akhlyustin escaped, but was killed while trying to reach Soviet lines in late July.
