Yugoslavia surrendered. For the invasion of the Soviet Union (Operation Barbarossa), Das Reich fought under Army Group Center, taking part in the Battle of Yelnya near Smolensk; it was then in the spearhead of Operation Typhoon aimed at the capture of the Soviet capital. By the time the division took part in the Battle of Moscow, it had lost 60 percent of its combat strength. It was further reduced in the Soviet Winter counter-offensive: for example, the Der Führer Regiment was down to 35 men out of the 2,000 that had started the campaign in June. The division was "mauled". By February 1942, it had lost 10,690 men. By mid-1942, the division was pulled out of the fighting line and sent to the west to refit as a Panzergrenadier division. In January 1943, the division was transferred back from France to the Eastern Front. There it participated in the fighting around Kharkov. Here the unit engaged in some heavy fighting against 1st Guards Cavalry Corps, among other units. Thereafter, it was one of three SS divisions which made up the II SS Panzer Corps, which took part in the Battle of Kursk that summer. The division operated in the southern sector of the Kursk bulge during the Battle of Prokhorovka. It was pulled out of the battle along with the other SS divisions when the offensive was discontinued, giving the strategic initiative to the Red Army. The Battle of Kursk was the first time that a German strategic offensive was halted before it could break through enemy defences and penetrate to its strategic depths. In October, the division was redesignated, this time as SS Panzer Division Das Reich to reflect its complement of tanks.

The location was chosen so that the division could respond quickly to the anticipated Allied invasion of France on either the Atlantic Coast or the Mediterranean Sea. In May the division received 37 Panzer IV and 55 Panther tanks, well below the official complement of 62 of each, but a full complement of 30 Sturmgeschütz III assault guns. Fuel and truck shortages hampered training and movement and many of the more than 15,000 men in the division were recent recruits and inadequately trained. The Allied Normandy landings took place on 6 June 1944. On
