The army traces its heritage back to the 1st Tank Army, formed twice in July 1942 and in January 1943 and converted into the 1st Guards Tank Army in January 1944. The army fought as part of the Red Army on the Eastern Front during World War II. The army was commanded throughout most of the war by Mikhail Katukov.

It fought on the defensive during Case Blue, ultimately being partially destroyed and disbanded. After its reformation in 1943, it participated in the Battle of Kursk, the Proskurov-Chernovtsy Operation, the Lvov-Sandomierz Operation, the Vistula-Oder Offensive and the Battle of Berlin. After the war, the army was stationed in East Germany as part of the Group of Soviet Forces in Germany.

After the end of the Cold War and the resultant withdrawal of Soviet units in Germany, the army was relocated to Smolensk, and disbanded in 1999. The army was reformed in 2014 as part of Russia's military expansion. This reformed army fought in the Russian invasion of Ukraine, where it was claimed to have suffered heavy casualties following its eventual retreats from the north and later Kharkiv.
