The 1st Guards Tank Army () is a tank army of the Russian Ground Forces. 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 in the early defense during the Battle of Stalingrad, and Operation Uranus, and participated in the Battle of Kursk, Proskurov-Chernovtsy Operation, Lvov-Sandomierz Operation, 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 2022 Russian invasion of Ukraine, where it is said to have suffered heavy casualties following its eventual retreats from the Northeast and later Kharkiv. First formation The 1st Tank Army was first formed within the Stalingrad Front from the 38th Army in July 1942, under the command of Major General Kirill Moskalenko. The army was encircled and partially destroyed. It was disbanded as a result in August 1942, its headquarters becoming the Southeastern Front headquarters. Second formation The 1st Tank Army was formed a second time on 30 January 1943 (order No.46021) from the headquarters of the 29th Army, under the command of famous armoured troops commander Lieutenant General of Tank Troops Mikhail Katukov, personally appointed by Stalin. The army was transferred to the North-Western Front. The 3rd Mechanised Corps (later to become 8th Guards Mechanised Corps) and 6th Tank Corps (later to become 11th Guards Tank Corps) joined it on formation, and served with the army throughout the war. It was quickly transferred to Voronezh Front for the defense of the Kursk salient's southern shoulder. It was awarded a Guards title and became the 1st Guards Tank Army in April 1944, and Katukov was promoted to Colonel General. On 1 January 1945, the Army's principal combat formations were: 8th Guards Mechanized Corps (Major General Ivan Dremov) (3 January 1944 – 9 May 1945) 19th Guards Mechanized Brigade 20th
