T-34The T-34 is a Soviet medium tank from World War II. When introduced, its 76.2 mm (3 in) tank gun was more powerful than its contemporaries, and its 60-degree sloped armour provided good protection against anti-tank weapons. The T-34 had a profound effect on the conflict on the Eastern Front, and had a long-lasting impact on tank design. The tank was praised by multiple German generals when encountered during Operation Barbarossa, although its armour and armament were surpassed later in the war.
Soviet Air ForcesThe Soviet Air Forces (Военно-Воздушные Силы Союза Советских Социалистических Республик, VVS SSSR; literally "Military Air Forces of the Union of Soviet Socialist Republics"; initialism VVS, sometimes referred to as the "Red Air Force", were one of the air forces of the Soviet Union. The other was the Soviet Air Defence Forces. The Air Forces were formed from components of the Imperial Russian Air Service in 1917, and faced their greatest test during World War II.
Oberkommando der WehrmachtThe Oberkommando der Wehrmacht (ˈoːbɐkɔˌmando deːɐ̯ ˈveːɐ̯ˌmaxt; abbreviated OKW oːkaːˈveː); High Command of the Armed Forces) was the supreme military command and control office of Nazi Germany during World War II. Created in 1938, the OKW replaced the Reich Ministry of War and had oversight over the individual high commands of the country's armed forces: the army (Heer), navy (Kriegsmarine), and air force (Luftwaffe).
NKVDThe People's Commissariat for Internal Affairs (PCIA) (Narodný komissariat vnutrennih del (NKVD), nɐˈrod.nɨj kə.mjɪ.sə.rjɪˈat ˈvnut.rjɪ.njɪx̬ djel), abbreviated NKVD (НКВД ), was the interior ministry of the Soviet Union. Established in 1917 as NKVD of the Russian Soviet Federative Socialist Republic, the agency was originally tasked with conducting regular police work and overseeing the country's prisons and labor camps. It was disbanded in 1930, with its functions being dispersed among other agencies, only to be reinstated as an all-union commissariat in 1934.
Pincer movementThe pincer movement, or double envelopment, is a military maneuver in which forces simultaneously attack both flanks (sides) of an enemy formation. This classic maneuver is important throughout the history of warfare. The pincer movement typically occurs when opposing forces advance towards the center of an army that responds by moving its outside forces to the enemy's flanks to surround it. At the same time, a second layer of pincers may attack the more distant flanks to keep reinforcements from the target units.
