Stavka in the context of "3rd Ukrainian Front"

The Battle of Prokhorovka was fought on 12 July 1943 near Prokhorovka, 87 kilometres (54 mi) southeast of Kursk, in the Soviet Union, during the Second World War. Taking place on the Eastern Front, the engagement was part of the wider Battle of Kursk and occurred when the 5th Guards Tank Army of the Soviet Red Army attacked the II SS-Panzer Corps of the German Waffen-SS in one of the largest tank battles in history.

In April 1943, the German leadership began preparing for Operation Citadel, with the objective of enveloping and destroying the Soviet forces in the Kursk salient by attacking and breaking through the base of the salient from north and south simultaneously. The German offensive was delayed several times because of the vacillation of the leadership (Hitler repeatedly delayed launching the attack so that more Tiger tanks could be delivered to the front, hoping that a technical advantage would help him win the offensive) and the addition of more forces and new equipment. The Soviet high command, Stavka, had learned of the German intentions and so used the delay to prepare a series of defensive belts along the routes of the planned German offensive. The Soviet leadership also massed several armies deep behind their defences as the Stavka Reserve. The army group, the Steppe Front, was to launch counteroffensives once the German strength had dissipated. The 5th Guards Tank Army was the primary armoured formation of the Steppe Front.

The Kalinin Front (Russian: Калининский фронт, romanized: Kalininskiy front) was a major formation of the Red Army active in the Eastern Front of World War II, named for the city of Kalinin. It was formally established by Stavka directive on 17 October 1941 and allocated three armies: 22nd, 29th Army and 30th. In May 1942, the Air Forces of the Kalinin Front were reorganised as the 3rd Air Army, comprising three fighter, two ground attack, and one bomber division.

In November 1942 the Kalinin Front, along with the Western Front, launched Operation Mars against the German defenses in the Rzhev/Vyaz'ma salient. The 3rd Shock Army, now allocated to Kalinin Front, started the operation on 24 November by attacking Third Panzer Army at Velikiye Luki, and the next day the Kalinin and Western Fronts assaulted the entire perimeter of the Rzhev salient. The offensive involved the 41st, 22nd, 39th, 31st, 20th, and 29th Armies from both Fronts. The Front was then involved in the Battle of Velikiye Luki in January–March 1943. The 3rd Air Army supported both the Rzhev/Sychevka and the Velikiye Luki operations, but then appears to have been shifted to Northwestern Front briefly to cover the Demyansk bridgehead.

The Great Retreat was a strategic withdrawal and evacuation on the Eastern Front of World War I in 1915. The Imperial Russian Army gave up the salient in Galicia and Congress Poland. The Russian Empire's critically under-equipped military suffered great losses in the Central Powers' July–September summer offensive operations, which led to the Stavka ordering a withdrawal to shorten the front lines and avoid the potential encirclement of large Russian forces in the salient. While the withdrawal itself was relatively well-conducted, it was a severe blow to Russian morale.
