This new approach considered military strategy and tactics, but also introduced a new intermediate level of military art: operations. In the aftermath of several failures or defeats in the Russo-Japanese War, First World War and Polish–Soviet War, the Soviet High Command ( Stavka) focused on developing new methods for the conduct of war. The concept of deep operations was a national strategy, tailored to the economic, cultural and geopolitical position of the Soviet Union. The term comes from Vladimir Triandafillov, an influential military writer, who worked with others to create a military strategy with its own specialized operational art and tactics. It was a tenet that emphasized destroying, suppressing or disorganizing enemy forces not only at the line of contact but also throughout the depth of the battlefield. Deep operation ( Russian: Глубокая операция, glubokaya operatsiya), also known as Soviet Deep Battle, was a military theory developed by the Soviet Union for its armed forces during the 1920s and 1930s.
