Battles of Khalkhin Gol
After the Battles of Khalkhin Gol, the Soviet military broke into two camps; one side was represented by Spanish Civil War veterans General Pavel Rychagov of the Soviet Air Force, Soviet armour expert General Dimitry Pavlov, and Stalin's favorite, Marshal Grigory Kulik, Chief of Artillery Administration. The other side consisted of the Khalkhin Gol veterans led by Generals Zhukov and Grigory Kravchenko of the Soviet Air Force. The lessons of Russia's "first real war on a massive scale using tanks, artillery, and airplanes" at Khalkhin Gol went unheeded.
