This close-support Stuka unit fought principally in the southern sector of the Eastern Front in places like Stalingrad and the Caucasus.

On 23 September 1941, StG 2 attacked the Baltic Red Banner Fleet docked in Kronstadt harbour.

In late 1942, a Panzerjäger Staffel was formed within StG 2, which enjoyed such success that, after October 1943, a similar unit was added to each Stuka Geschwader.

During the spring of 1943 SG 2 worked up with modified Ju 87 G-1 'tank-busters' armed with two Rheinmetall-Borsig 37mm Flak 18 guns mounted under each wing.

At the end of the war, the commanding officer and a few other pilots flew their aircraft west and surrendered to the American forces.
