6th Guards Tank Army

The 6th Guards Order of Red Banner Tank Army was a tank army of the Soviet Union's Red Army, first formed during World War II and disbanded in Ukraine in the 1990s after the dissolution of the Soviet Union.

The 6th Tank Army's first major operation was the suppression of the Korsun-Cherkassy Pocket in January-February 1944. It then fought in the Iassy-Kishinev Offensive during August 1944 before gaining a Guards title in October 1944. Under its new title, it was soon engaged in the Battle of Debrecen on the 2nd Ukrainian Front, before fighting against the Germans during Operation Frühlingserwachen in January 1945. Pushing west, the tank army moved south of Vienna, Austria and pivoted to the north in a wide encircling maneuver that cut Vienna off from the rest of the German Reich.

The 6th Guards Tank Army was then moved to the Transbaikal Military District in order to take part in the Soviet invasion of Manchuria. The army, under the command of Colonel General A.G. Kravchenko, spearheaded the Transbaikal Front's offensive against the Japanese Kwantung Army on 9 August 1945. The 6th Guards Tank Army consisted of the 5th Guards Tank Corps, and 7th and 9th Guards Mechanised Corps, and many smaller formations, in all, a total of 1,019 tanks and self-propelled guns. For this operation, the tank army was restructured such that the infantry, artillery, and armored components were much more balanced than they had been during the war against the Germans. This was the first example of what proved to be the standard Soviet mechanized army organization during the Cold War. During the Soviet invasion of Manchuria, the Army was operating as part of the Transbaikal Front, and during the "Khingano-Mukden Operation", as it was known to the Soviets, the Army was tasked to advance 800 kilometers.

It was stationed in Mongolia, reporting to the Transbaikal Military District, for 15 years after the war. The friendship with China of those days and the Nikita Khrushchev military reductions changed the fate of the Army, and in 1959 it was relocated to Dnipropetrovsk in the Kiev Military District. Toward the end of the 1980s it retained three Guards Tank Divisions - the 17th, 42nd (the former 42nd Rifle Division) and the 75th (formerly the 75th Guards Rifle Division, though Lenskii disagrees and calls this division the 14th Guards Tank). On 11 November 1990, following the disbandment of the 75th (or 14th) Guards Tank Division, the reorganisation of the 42nd Guards Tank Division as the 5359th Base for Storage of Weapons and Equipment, and the arrival of the 93rd Guards Motor Rifle Division from the Southern Group of Forces, the Army had on hand 462 main battle tanks, all T-64s, 228 BMPs and BTRs, 218 other pieces of equipment of various types, and five helicopters (with the 16th Separate Mixed Aviation Squadron at Podgorodnoe).

After the dissolution of the Soviet Union it became part of the Ukrainian Ground Forces. At some point during the 1990s it was disbanded by being redesignated the 6th Army Corps. Today in Ukrainian service the 6th Army Corps is still based at Dnipropetrovsk and consists of several brigades, including the 17th Armored Brigade and the 93rd Mechanized Brigade.
