Калининский фронт
In the early months of the Great Patriotic War, Colonel Kurasov worked at the General Staff. He was promoted to Major General on October 28, 1941. In December 25, 1941 he was appointed Chief of Staff of 4th Shock Army (at the same time, Colonel General Yeremenko was appointed as the Army Commander) belonging to Northwestern Front and transferred to the Kalinin Front on January 22, 1942. During the Toropets–Kholm Offensive in January–February 1942, the Army troops moved nearly 300 kilometers in less than a month, an unprecedented result for the entire Soviet offensive phase of the Battle of Moscow. Since March 1942, Kurasov was appointed as Commanding General of the 4th Shock Army, which was at a relatively quiet sector of the Kalinin Front. Kurasov was promoted to the rank of Lieutenant General on May 21, 1942.
