The 185th Rifle Division was formed as an infantry division of the Red Army just as the Second World War was beginning, in the Oryol Military District, based on the pre-September 13, 1939 shtat. As a standard rifle division it took part in the Soviet occupation of Lithuania in June 1940. In early 1941 it was selected for conversion to a motorized infantry division, but in fact it had received little in the way of vehicles by the start of the German invasion and so was a rifle division in all but name. It was sent to join Northwestern Front in the Baltic states with its 21st Mechanized Corps, and was soon assigned to 27th Army. Under these commands the division retreated through July and August as the German 16th Army advanced behind in the general direction of Novgorod. On August 25 it was officially reorganized as a regular rifle division.

The 305th Rifle Division was formed for the first time as a standard Red Army rifle division shortly after the German invasion. It was soon sent north to the Volkhov Front near Novgorod. In the winter of 1942 it participated in an offensive to try to break the siege of Leningrad which ended with it and most of the rest of the attacking force being cut off and gradually annihilated during the spring. A second 305th was raised a few months later in the southern part of the front, where it distinguished itself in the final liberation of Belgorod. It continued in combat through Ukraine and Poland before ending the war near Prague.
