Information:  - The Soviet Union, officially the Union of Soviet Socialist Republics (USSR " ) was a socialist state in Eurasia that existed from 1922 to 1991. A union of multiple subnational republics, its government and economy were highly centralized. The Soviet Union was a one-party federation, governed by the Communist Party with Moscow as its capital.  - Coastal artillery is the branch of the armed forces concerned with operating anti-ship artillery or fixed gun batteries in coastal fortifications.  - The Swedish Armed Forces is the government agency that forms the military forces of Sweden, and which is tasked with defence of the country, as well as promoting Sweden's wider interests, supporting international peacekeeping efforts, and providing humanitarian aid.  - The Amphibious Corps is the coastal defence arm of the Swedish Navy. Until 2000 it was known as Coastal Artillery, but the name was changed to reflect its different role in a post-Cold War world, where its amphibious special operations arm, the Coastal Rangers, has grown in significance while its coastal batteries have been decommissioned.   - Warsaw (; see also other names) is the capital and largest city of Poland. It stands on the Vistula River in east-central Poland, roughly from the Baltic Sea and from the Carpathian Mountains. Its population is estimated at 1.750 million residents within a greater metropolitan area of 3.105 million residents, which makes Warsaw the 9th most-populous capital city in the European Union. The city limits cover , while the metropolitan area covers .  - World War II (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the world's nationsincluding all of the great powerseventually forming two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. In a state of "total war", the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources. Marked by mass deaths of civilians, including the Holocaust (in which approximately 11 million people were killed) and the strategic bombing of industrial and population centres (in which approximately one million were killed, and which included the atomic bombings of Hiroshima and Nagasaki), it resulted in an estimated 50 million to 85 million fatalities. These made World War II the deadliest conflict in human history.  - The Truman Doctrine was an American foreign policy created to counter Soviet geopolitical spread during the Cold War. It was first announced to Congress by President Harry S. Truman on March 12, 1947 and further developed on July 12, 1948 when he pledged to contain Soviet threats to Greece and Turkey. American military force was usually not involved, but Congress appropriated free gifts of financial aid to support the economies and the military of Greece and Turkey. More generally, the Truman doctrine implied American support for other nations threatened by Soviet communism. The Truman Doctrine became the foundation of American foreign policy, and led, in 1949, to the formation of NATO, a military alliance that is still in effect. Historians often use Truman's speech to date the start of the Cold War. Truman told Congress that "it must be the policy of the United States to support free people who are resisting attempted subjugation by armed minorities or by outside pressures." Truman reasoned that because the totalitarian regimes coerced free peoples, they represented a threat to international peace and the national security of the United States. Truman made the plea amid the crisis of the Greek Civil War (194649). He argued that if Greece and Turkey did not receive the aid that they urgently needed, they would inevitably fall to communism with grave consequences throughout the region. Because Turkey and Greece were historic rivals, it was necessary to help both equally even though the threat to Greece was more immediate. Historian Eric Foner argues the Truman Doctrine "set a precedent for American assistance to anticommunist regimes throughout the world, no matter how undemocratic, and for the creation of a set of global military alliances directed against the Soviet Union."  - The London and Paris Conferences were two related conferences in London and Paris in SeptemberOctober 1954 to determine the status of West Germany. The talks concluded with the signing of the Paris Agreements (Paris Pacts, or Paris Accords), which granted West Germany full sovereignty, ended the occupation, and allowed its admittance to NATO. Furthermore, both West Germany and Italy joined the Brussels Treaty on 23 October 1954. The Agreements went into force on 5 May 1955. The participating powers included France, the United Kingdom, Belgium, the Netherlands, Luxembourg, West Germany, Italy, Canada, the United States, and remaining NATO members.  - The term satellite state designates a country that is formally independent in the world, but under heavy political, economic and military influence or control from another country. The term was coined by analogy to planetary objects orbiting a larger object, such as smaller moons revolving around larger planets, and is used mainly to refer to Central and Eastern European countries of the Warsaw Pact during the Cold War or to Mongolia between 1924 and 1990, for example. As used for Central and Eastern European countries it implies that the countries in question were "satellites" under the hegemony of the Soviet Union. In some contexts it also refers to other countries in the Soviet sphere of influence during the Cold Warsuch as North Korea (especially in the years surrounding the Korean War of 19501953) and Cuba (particularly after it joined the Comecon in 1972). In Western usage, the term has seldom been applied to states other than those in the Soviet orbit. In Soviet usage, the term applied to the states in the orbit of Nazi Germany and Fascist Italy.  - The Swedish Royal Navy is the naval branch of the Swedish Armed Forces. It is composed of surface and submarine naval units  the Fleet (Kungliga Flottan)  as well as marine units, the Amphibious Corps (Amfibiekåren).  - The Western Bloc or Capitalist Bloc during the Cold War refers to the countries allied with the NATO against the Soviet Union and its allies. The latter were referred to as the "Eastern Bloc", a more common term in English than "Western Bloc". The governments and press of the Western Bloc were more inclined to refer to themselves as the "Free World" or the "Western world". "Western Europe" is a controversial term used to refer to democratic countries in Europe during the Cold War, but the concept is sometimes still used for quick reference by the media.  - West Germany is the common English name for the Federal Republic of Germany or FRG (or "RFA") in the period between its creation on 23 May 1949 to German reunification on 3 October 1990. During this Cold War era, NATO-aligned West Germany and Warsaw Pact-aligned East Germany were divided by the Inner German border. After 1961 West Berlin was physically separated from East Berlin as well as from East Germany by the Berlin Wall. This situation ended when East Germany was dissolved and its five states joined the ten states of the Federal Republic of Germany along with the reunified city-state of Berlin. With the reunification of West and East Germany, the Federal Republic of Germany, enlarged now to sixteen states, became known simply as "Germany". This period is also referred to as the Bonn Republic ("Bonner Republik") by historians, alluding to the interwar Weimar Republic and the post-reunification Berlin Republic.  - The Warsaw Pact, formally the Treaty of Friendship, Co-operation, and Mutual Assistance and sometimes, informally, WarPac. was a collective defense treaty among the Soviet Union and seven other Soviet satellite states in Central and Eastern Europe in existence during the Cold War. The Warsaw Pact was the military complement to the Council for Mutual Economic Assistance (CoMEcon), the regional economic organization for the communist states of Central and Eastern Europe. The Warsaw Pact was created in reaction to the integration of West Germany into NATO in 1955 per the London and Paris Conferences of 1954, but it is also considered to have been motivated by Soviet desires to maintain control over military forces in Central and Eastern Europe.  - Eastern Europe, also known as East Europe, is the eastern part of the European continent. There is no consensus on the precise area it covers, partly because the term has a wide range of geopolitical, geographical, cultural, and socioeconomic connotations. There are "almost as many definitions of Eastern Europe as there are scholars of the region". A related United Nations paper adds that "every assessment of spatial identities is essentially a social and cultural construct".  - Artillery is a class of large military weapons built to fire munitions far beyond the range and power of infantry's small arms. Early artillery development focused on the ability to breach fortifications, and led to heavy, fairly immobile siege engines. As technology improved, lighter, more mobile field artillery developed for battlefield use. This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility providing the largest share of an army's total firepower.  - The Swedish coastal artillery ( Swedish : Kustartilleriet , KA ) has its origin in the Archipelago Artillery that was raised in 1866 . The Coastal Artillery was formed from the Archipelago Artillery , the Marine Regiment and parts of the Artillery in 1902 . Kustartilleriet , abbreviated KA , was an independent branch within the Swedish Navy until July 1 , 2000 , when the Swedish Coastal Artillery was disbanded and reorganised as the Amfibiekåren ( Swedish Amphibious Corps ) . The changed name and new structure were to reflect the new tasks that the old Coastal Artillery had moved to after the end of the Cold War and the demise of the Warsaw Pact .  - The armed forces of a country are its government-sponsored defense, fighting forces, and organizations. They exist to further the foreign and domestic policies of their governing body and to defend that body and the nation it represents from external and internal aggressors. In broad usage, the terms "armed forces" and "military" are often treated synonymously, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. Armed force is the use of armed forces to achieve political objectives. The study of the use of armed forces is called military science. Broadly speaking, this involves considering offense and defense at three "levels": strategy, operational art, and tactics. All three levels study the application of the use of force in order to achieve a desired objective.  - The Eastern Bloc was the group of communist states of Central and Eastern Europe, generally the Soviet Union and the countries of the Warsaw Pact. The terms Communist Bloc and Soviet Bloc were also used to denote groupings of states aligned with the Soviet Union, although these terms might include states outside Central and Eastern Europe.  - The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by the English kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years War against the kingdom of France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is known as the Senior Service.  - The North Atlantic Treaty Organization (NATO  '), also called the North Atlantic Alliance, is an intergovernmental military alliance based on the North Atlantic Treaty which was signed on 4 April 1949. The organization constitutes a system of collective defence whereby its member states agree to mutual defence in response to an attack by any external party. Three NATO members are permanent members of the United Nations Security Council with the power to veto and are officially nuclear-weapon states: the United States, France and the United Kingdom. NATO's headquarters are located in Haren, Brussels, Belgium, where the Supreme Allied Commander also resides. Belgium is one of the 28 member states across North America and Europe, the newest of which, Albania and Croatia, joined in April 2009. An additional 22 countries participate in NATO's Partnership for Peace program, with 15 other countries involved in institutionalized dialogue programmes. The combined military spending of all NATO members constitutes over 70% of the global total. Members' defence spending is supposed to amount to 2% of GDP.  - Central and Eastern Europe, abbreviated CEE, is a generic term for the group of countries in Central Europe, Southeast Europe, Northern Europe, and Eastern Europe, usually meaning former communist states in Europe. It is in use after the collapse of the Iron Curtain in 198990. In scholarly literature the abbreviations CEE or CEEC are often used for this concept.  - The 20th century was a century that began on  January 1, 1901 and ended on December 31, 2000. It was the tenth and final century of the 2nd millennium. It is distinct from the century known as the 1900s (sometimes written as 19XX), which began on January 1, 1900 and ended on December 31, 1999.  - The Cold War was a state of political and military tension after World War II between powers in the Eastern Bloc (the Soviet Union and its satellite states) and powers in the Western Bloc (the United States, its NATO allies and others). Historians do not fully agree on the dates, but a common timeframe is the period (the second half of the 20th century) between 1947, the year the Truman Doctrine (a U.S. policy pledging to aid nations threatened by Soviet expansionism) was announced, and 1991, the year the Soviet Union collapsed.
