Polish Armed Forces in the EastThe Polish Armed Forces in the East (Polskie Siły Zbrojne na Wschodzie), also called Polish Army in the USSR, were the Polish military forces established in the Soviet Union during World War II. Two armies were formed separately and at different times. Anders' Army, created in the second half of 1941, was loyal to the Polish government-in-exile. After Operation Barbarossa and the consequent Polish-Soviet Sikorski–Mayski agreement, an amnesty for Polish citizens in the Soviet Union was declared, which made the formation of Polish military units possible.
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.
Tanks in the German ArmyThis article deals with the tanks (Panzer) serving in the German Army (Deutsches Heer) throughout history, such as the World War I tanks of the Imperial German Army, the interwar and World War II tanks of the Nazi German Wehrmacht, the Cold War tanks of the West German and East German Armies, all the way to the present day tanks of the Bundeswehr. The development of tanks in World War I began as an attempt to break the stalemate which trench warfare had brought to the Western Front.
Battle of BerlinThe 'Battle of Berlin, designated as the Berlin Strategic Offensive Operation by the Soviet Union, and also known as the Fall of Berlin', was one of the last major offensives of the European theatre of World War II. After the Vistula–Oder offensive of January–February 1945, the Red Army had temporarily halted on a line east of Berlin. On 9 March, Germany established its defence plan for the city with Operation Clausewitz. The first defensive preparations at the outskirts of Berlin were made on 20 March, under the newly appointed commander of Army Group Vistula, General Gotthard Heinrici.
Estonia in World War IIEstonia declared neutrality at the outbreak of World War II (1939–1945), but the country was repeatedly contested, invaded and occupied, first by the Stalinist Soviet Union in 1940, then by Nazi Germany in 1941, and ultimately reinvaded and reoccupied in 1944 by the Soviet Union. Immediately before the outbreak of World War II, in August 1939, Germany and the Soviet Union signed the Nazi-Soviet Pact (also known as the Molotov–Ribbentrop Pact, or the 1939 German-Soviet Nonaggression Pact), concerning the partition and disposition of Poland, Finland, Lithuania, Latvia, and Estonia, in its Secret Additional Protocol.
Penal military unitA penal military unit, also known as a penal formation, disciplinary unit, or just penal unit (usually named for their formation and size, such as penal battalion for battalions, penal regiment for regiments, penal company for companies, etc.), is a military formation consisting of convicts mobilized for military service. Such formations may consist of military prisoners convicted under military law, civilian prisoners convicted in civilian courts, prisoners of war who have chosen to side with their captors, or a combination of these groups.
Battle of the CaucasusThe Battle of the Caucasus is a name given to a series of Axis and Soviet operations in the Caucasus area on the Eastern Front of World War II. On 25 July 1942, German troops captured Rostov-on-Don, Russia, opening the Caucasus region of the southern Soviet Union, and the oil fields beyond at Maikop, Grozny, and ultimately Baku, to the Germans. Two days prior, Adolf Hitler issued a directive to launch such an operation into the Caucasus region named Operation Edelweiß.
History of the Soviet UnionThe history of Soviet Russia and the Soviet Union (USSR) reflects a period of change for both Russia and the world. Though the terms "Soviet Russia" and "Soviet Union" often are synonymous in everyday speech (either acknowledging the dominance of Russia over the Soviet Union or referring to Russia during the era of the Soviet Union), when referring to the foundations of the Soviet Union, "Soviet Russia" often specifically refers to brief period between the October Revolution of 1917 and the creation of the Soviet Union in 1922.
KantokuenKantokuen (関特演, from 関東軍特種演習, Kantōgun Tokushu Enshū, "Kwantung Army Special Maneuvers") was an operational plan created by the General Staff of the Imperial Japanese Army for an invasion and occupation of the Russian Far East, capitalizing on the outbreak of the Soviet-German War in June 1941. Involving seven Japanese armies and a major portion of the empire's naval and air forces, it would have been the largest combined arms operation in Japanese history up to that point, and one of the largest of all time.
