The 399th Rifle Division was an infantry division of the Red Army. Partially raised in 1941, this formation was abandoned until a second formation began in February 1942, this time in the far east of Siberia. The formation lasted until July, after which it was moved west to join the Stalingrad Front in the great bend of the Don River. Badly mauled in its first actions, it was rebuilt west of the Don in late July, and went on to contest the German advance right into the center of the city. The remnants of the division were pulled out and sent north to Bryansk Front, and the once-again rebuilt division went on to serve in the winter offensive against the German forces in the salient around Oryol. It was present on the right flank of the Kursk salient during the German offensive in July 1943
