"After the extensive airborne activity during the winter campaign of 1941–42, airborne forces underwent another major reorganization the following summer. Responding to events in southern Russia, where German troops had opened a major offensive that would culminate in the Stalingrad battles, the ten airborne corps, as part of the Stavka strategic reserves, deployed southward. Furthermore, the Stavka converted all ten airborne corps into guards rifle divisions to bolster Soviet forces in the south. Nine of these divisions participated in the battles around Stalingrad, and one took part in the defense of the northern Caucasus region."
