World War II 

In the Battle of Kursk (Operation Citadel), General Vasily Ryazanov became a master in the use of attack aircraft en masse, developing and improving the tactics of Il-2 operations in co-ordination with infantry, artillery and armored troops. Il-2s at Kursk used the "circle of death" tactic: up to eight Sturmoviks formed a defensive circle, each plane protecting the one ahead with its forward machine guns, while individual Il-2s took turns leaving the circle, attacking a target, and rejoining the circle. Ryazanov was later awarded the Gold Star of Hero of Soviet Union twice, and the 1st Assault Aircraft Corps under his command became the first unit to be awarded the honorific title of Guards. In 1943, one loss corresponded to 26 Sturmovik sorties. About half of those lost were shot down by fighters, the rest falling to anti-aircraft fire.

Part of the 'Operational Army' 
The 1st Assault Aviation Corps was part of the 'operational army' ((:ru:Действующая армия и флот, in combat) from October 17, 1942 to February 5, 1944, a period of 477 days. The corps was still part of the 'operational army' after its elevation to Guards status and remained in combat until 11 May 1945. The corps thus spent 937 days in combat.
