300th Rifle Division (Soviet Union)
military unit

The 300th Rifle Division began service as a standard Red Army rifle division shortly after the German invasion, and fought in the southwestern part of the Soviet-German front for nearly two years following. It was able to escape the encirclement east of Kiev in September, 1941, and then fought to defend, and later to try to liberate, the city of Kharkov during 1941-42. After falling back under the weight of the German 1942 summer offensive, the division began distinguish itself during Operation Uranus in late 1942, when it helped defeat the German attempt to relieve Sixth Army and later in the pursuit of the defeated Axis forces and the second liberation of Rostov-na-Donu. In recognition of these successes it was raised to Guards status as the 87th Guards Rifle Division. A second 300th Rifle Division was raised a few months later and fought briefly but very successfully against the Japanese in Manchuria in August 1945. The second formation became the 3rd Tank Division in the Far East postwar and was redesignated as the 46th Tank Division in 1957 before disbanding in 1959.

This brief starts where responsible research should: with the source description of “300th Rifle Division (Soviet Union)” as military unit. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as military unit. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 24, 2026. The linked authority identifier is Q18234796. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1941, 1942, 1945 and 1957.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
