Warriors of the 372nd Infantry Division of the Red Army in the Battle of Leningrad. The photograph shows teams of 14.5-mm anti-tank rifles of the Degtyarev PTRD-41 system.
Three Siberian divisions took part in the defense of Leningrad (the 178th and 372th rifle divisions, the 87th cavalry division), and it was the soldiers of the 372nd rifle division that in January 1943 cut a gap in the Nazi blockade ring.
