The 304th Rifle Division had its roots in the 109th Mechanized Division, which served before the Great Patriotic War as a mixed armor and infantry formation. Soon after the German invasion it was reorganized as a standard rifle division and renumbered as the 304th. It served in the southwestern part of the Soviet-German front for more than a year and a half, fighting under difficult conditions, including the German summer offensive of 1942. The division did not distinguish itself until Operation Uranus in late 1942 and the subsequent Operation Ring, in which it helped defeat the encircled German Sixth Army. In recognition of these successes, even before the German surrender at Stalingrad, it was raised to Guards status as the 67th Guards Rifle Division. A second 304th was raised six months
