The Red Army's 7th Guards Army was re-designated from the Soviet 64th Army on April 16, 1943.
64th Army had originally been formed from 1st Reserve Army in July 1942, and alongside the 62nd Army, fought the German offensive during the Battle of Stalingrad to a standstill, for which it was raised to Guards status. General Lieutenant M.S. Shumilov, who had commanded the 64th Army, continued to command 7th Guards Army through the rest of the war, though he was promoted to General Colonel in October 1943.
It included the 15th, 36th, 72nd, 73rd, 78th and 81st Guards Rifle Divisions, which were incorporated in the 24th and 25th Guards Rifle Corps. As part of the Voronezh Front and the Steppe Front since July 18, 1943, the Army participated in the Battle of Kursk and the Battle for the Dnieper River from July through August, 1943. Subsequently, as part of the 2nd Ukrainian Front, it participated in the Kirovograd Offensive, and those of Uman and Botoşani, Iassy-Kishinev, Debrecen, Budapest, Bratislava and Brno, and Prague.
The 7th Guards Army was stationed in Austria as part of the Central Group of Forces briefly after the war. On 1 May 1945 it comprised 23rd Rifle Corps (19th and 252nd Rifle Divisions), 25th Guards Rifle Corps (4th and 6th Guards Airborne Divisions, 25th Guards Rifle Division, 303rd Rifle Division), and 27th Guards Rifle Corps (72nd Guards, 141st, 375th, and 409th Rifle Divisions). In 1946 it comprised three rifle corps totaling nine divisions, and that year General Ivan Fedyuninsky took command for a period. These formations were reassigned to the North Caucasus, Tavria and Kiev Military Districts and the Army HQ arrived at Yerevan in the Transcaucasus Military District to take control of the 75th and 261st Rifle Divisions, soon followed by the 26th Mechanised Division and the 164th Rifle Division. In the late 1980s the Army consisted of:15th Motor Rifle Division (former 15th Rifle Division) – Kirovakan
75th Motor Rifle Division (former 75th Rifle Division) – Nakhichevan, Category "C" with 5–10% manning
127th Motor Rifle Division (former 261st Rifle Division) – Leninakan, Armenia
164th Motor Rifle Division (former 164th Rifle Division) – Yerevan
In November 1988 Colonel Lev Rokhlin became the commander of the 75th Motorized Rifle Division (MRD). In early 1990 the division was transferred to the Soviet Border Troops of the KGB, and Rokhlin was promoted to major-general in February of the same year. Later the division was transferred to the Azerbaijani Army, but to the representatives of the Nakhichivan government rather than authorities from the Azerbaijani Ministry of Defence.
The 7th Guards Army was disbanded on 14 August 1992, following the dissolution of the Soviet Union. General Lieutenant Fyodor Reut was among the Army's last commanders. Most of the formations disbanded/dissolved, among them the 15th MRD, whose equipment were partly handed over to Armenia when it disbanded in 1992. The 15th MRD's traditions, honors and awards were transferred to the 5209th Weapons and Equipment Storage Base. The 127th MRD later became the Russian 102nd Military Base.
