This close-support Stuka unit fought principally in the southern sector of the Eastern Front in places like Stalingrad and the Caucasus. The early two Schlachtgeschwader 1 and 2 were abbreviated SchlG, the reformed Stukageschwader in 1943 were abbreviated SG. The 4 SchlG Gruppen were integrated into the former Stuka (StG) and Schnellkampfgeschwader (SKG) to form SG 2, 4, 77 and 10.
