111-577: Kalashnikov Concern has stated that the RPL-20 is a new design, rather than being a derivative of the ubiquitous Kalashnikov-pattern rifle series. It is a belt-fed, open bolt, fully automatic light machine gun with a rotating bolt and a long-stroke gas piston. The RPL-20 uses a non-disintegrating linked belt similar to the RPD . Alternative designs experimented with a dual-feed option (i.e., capable of both magazine- and belt-feed), considered to be an improvement over

222-655: A famine between 1930 and 1933 that killed millions. The Soviet forced labour camp system of the Gulag was expanded. During the late 1930s, Stalin's government conducted the Great Purge to remove opponents, resulting in mass death, imprisonment, and deportation. In 1939, the USSR and Nazi Germany signed a nonaggression pact , but in 1941, Germany invaded the Soviet Union in the largest land invasion in history, opening

333-526: A belt-fed, intermediate caliber machine gun. The MVD solicited designs for a similar weapon beginning in 2011, for use by counter-terror teams, though it did not follow through with any actual orders. There have, however, been competitions to replace the RPK-74, leading to the selection of the RPK-16 for field trials. Based on feedback from these field trials, Kalashnikov Concern independently began development of

444-541: A closer relationship with France and Britain. In 1939, half a year after the Munich Agreement , the USSR attempted to form an anti-Nazi alliance with France and Britain. Adolf Hitler proposed a better deal, which would give the USSR control over much of Eastern Europe through the Molotov–Ribbentrop Pact . In September, Germany invaded Poland, and the USSR also invaded later that month, resulting in

555-519: A greater union which he initially named as the Union of Soviet Republics of Europe and Asia (Russian: Союз Советских Республик Европы и Азии , romanized : Soyuz Sovyetskikh Respublik Evropy i Azii ). Joseph Stalin initially resisted Lenin's proposal but ultimately accepted it, and with Lenin's agreement he changed the name to the Union of Soviet Socialist Republics (USSR), although all republics began as socialist soviet and did not change to

666-454: A knob on the left side of the rear sight. Because the front sight of the RPD must be partially disassembled in order to adjust windage, in practice the front sight would have been zeroed for windage and then locked in place. Adjustment for windage in the field would have been accomplished using the knob on the rear sight. A number of RPDs were fitted with a side rail (attached to the left side of

777-597: A new profitable market. In the late 1920s and early 1930s, Stalin ordered Marxist-Leninist parties across the world to strongly oppose non-Marxist political parties, labour unions or other organizations on the left, which they labelled social fascists . In the usage of the Soviet Union, and of the Comintern and its affiliated parties in this period, the epithet fascist was used to describe capitalist society in general and virtually any anti-Soviet or anti-Stalinist activity or opinion. Stalin reversed himself in 1934 with

888-474: A non-removable barrel with a three-position gas adjustment valve used to control the performance of the gas system. It is also equipped with a folding integral bipod , wooden shoulder stock , foregrip and pistol grip . The firearm strips down into the following major groups: the receiver and barrel, bolt, bolt carrier, feed tray and feed cover, the recoil mechanism and the trigger group and stock. The RPD fires from an open bolt in full auto only. There

999-423: A number of spring steel "fingers" on the lid of the clam-shell case which press on the contents of the cleaning kit when closed to prevent rattling. One end of the clam-shell case has a notch from which the screwdriver end of the multi-tool can protrude. During its service life, the weapon was modernized several times. Initially, the gas block was modified as was the rear sight, where the windage adjustment knob for

1110-442: A pair of hinged flaps set in recesses on each side of the receiver . The movement of these flaps and the resulting locking and unlocking action is controlled by carefully angled surfaces on the bolt carrier assembly . The weapon fires from an open bolt . The RPD is hammer fired from an open bolt. The hammer forms part of the rear of the bolt carrier (which is connected to the gas piston), which continues moving forward for

1221-400: A short distance after the round is chambered and the bolt locked, the hammer face then striking the rear of the free floating firing pin which passes through the length of the bolt. Locking occurs by means of lateral flaps located along the sides of the bolt, which are forced outwards (by the angled sides of the hammer) into recesses cut into the receiver body, after which firing occurs when

1332-503: A simpler belt that held the cartridges in place using an L-shaped tab at the rear of the belt. The Chinese copied the Hungarian design for their belts, albeit in 25-round lengths instead of 50. RPD belt segments are connected using a round of ammunition that holds the last link of the first belt and the first link of the next belt together. When the last round in a belt segment is fired, that belt segment disconnects and falls away, reducing

1443-631: A status that is retained by the Russian Federation . Covering a sixth of Earth's land surface, its size was comparable to that of North America . Two other successor states, Kazakhstan and Ukraine , rank among the top 10 countries by land area, and the largest country entirely in Europe, respectively. The European portion accounted for a quarter of the country's area and was the cultural and economic center. The eastern part in Asia extended to

1554-502: A total of 100 rounds. The RPD can also feed belts that are not contained in a drum if, for example, there is a need for more than 100 rounds of linked ammunition at a time. The feed system is operated by a roller connected to the reciprocating bolt carrier assembly. The belt is pulled into the gun during the rearward motion of the bolt carrier. The noteworthy flaw in the drum's design is its unreliability in dirty conditions; it can become clogged with filth and other natural elements. The RPD

1665-475: A union of equals, in practice the Soviet Union was dominated by Russians . The domination was so absolute that for most of its existence, the country was commonly (but incorrectly) referred to as 'Russia'. While the Russian SFSR was technically only one republic within the larger union, it was by far the largest (both in terms of population and area), most powerful, and most highly developed. The Russian SFSR

1776-730: Is a 7.62x39mm light machine gun developed in the Soviet Union by Vasily Degtyaryov for the 7.62×39mm M43 intermediate cartridge . It was created as a replacement for the DP machine gun chambered for the 7.62×54mmR round. It is a precursor of most squad automatic weapons . It was succeeded in Soviet service by the RPK . Work on the weapon commenced in 1943. Three prominent Soviet engineers were asked to submit their own designs: Vasily Degtyaryov , Sergei Simonov and Alexei Sudayev . Among

1887-573: Is derived from the Russian word sovet (Russian: совет ), meaning 'council', 'assembly', 'advice', ultimately deriving from the proto-Slavic verbal stem of * vět-iti ('to inform'), related to Slavic věst ('news'), English wise . The word sovietnik means 'councillor'. Some organizations in Russian history were called council (Russian: совет ). In the Russian Empire ,

1998-425: Is equipped with a set of open-type iron sights . These consist of a front post and a notched rear sight mounted on a tangent. Both the front and rear sights on the RPD are adjustable for windage and elevation . The front sight is adjusted up or down for elevation using a tool included in the issued cleaning kit. To adjust the front sight for windage, the smaller of the two wrenches on the multi-tool included in

2109-655: Is his background, his education , his profession . These are the questions that will determine the fate of the accused. That is the meaning and essence of the Red Terror ." During his rule, Stalin always made the final policy decisions. Otherwise, Soviet foreign policy was set by the commission on the Foreign Policy of the Central Committee of the Communist Party of the Soviet Union , or by

2220-435: Is no provision for semi-auto fire , although RPD gunners were trained to fire in short bursts to prolong the life of the non-quick-change barrels. The RPD feeds ammunition from the left side using a metallic, open-link, non-disintegrating belt typically holding 100 rounds of 7.62x39 ammunition. Unlike many other belt -fed automatic weapons, where the rounds must be pulled out the rear of the belt and then pushed forward into

2331-520: The Council of People's Commissars ), headed by the Chairman (Premier) and managing an enormous bureaucracy responsible for the administration of the economy and society. State and party structures of the constituent republics largely emulated the structure of the central institutions, although the Russian SFSR, unlike the other constituent republics, for most of its history had no republican branch of

2442-606: The Eastern Front of World War II . The Soviets played a decisive role in defeating the Axis powers , suffering an estimated 27 million casualties , which accounted for most Allied losses. In the aftermath of the war , the Soviet Union consolidated the territory occupied by the Red Army , forming satellite states , and undertook rapid economic development which cemented its status as a superpower . Geopolitical tensions with

2553-755: The Land Forces , the Air Force , the Navy , Joint State Political Directorate (OGPU) and the Internal Troops . The OGPU later became independent and in 1934 joined the NKVD secret police, and so its internal troops were under the joint leadership of the defense and internal commissariats. After World War II, Strategic Missile Forces (1959), Air Defense Forces (1948) and National Civil Defense Forces (1970) were formed, which ranked first, third, and sixth in

2664-528: The Moscow State Institute of International Relations . The Marxist-Leninist leadership of the Soviet Union intensely debated foreign policy issues and changed directions several times. Even after Stalin assumed dictatorial control in the late 1920s, there were debates, and he frequently changed positions. During the country's early period, it was assumed that Communist revolutions would break out soon in every major industrial country, and it

2775-657: The Pacific Ocean to the east and Afghanistan to the south, and, except some areas in Central Asia , was much less populous. It spanned over 10,000 kilometres (6,200 mi) east to west across 11 time zones , and over 7,200 kilometres (4,500 mi) north to south. It had five climate zones: tundra , taiga , steppes , desert and mountains . The USSR, like Russia , had the world's longest border , measuring over 60,000 kilometres (37,000 mi), or 1 + 1 ⁄ 2 circumferences of Earth. Two-thirds of it

2886-790: The Popular Front program that called on all Marxist parties to join with all anti-Fascist political, labour, and organizational forces that were opposed to fascism , especially of the Nazi variety. The rapid growth of power in Nazi Germany encouraged both Paris and Moscow to form a military alliance, and the Franco-Soviet Treaty of Mutual Assistance was signed in May 1935. A firm believer in collective security, Stalin's foreign minister Maxim Litvinov worked very hard to form

2997-547: The RPK , while PK machine guns would be issued at the company level to provide heavier fire. While the RPK was a simpler, lighter, easier to use weapon than the RPD it replaced, it did not always perform as well as had been hoped. The weapon's magazine feed system, light weight, and fixed barrel made it excellent for one-man operation, but also hampered its ability to provide continuous suppressive fire. As such, some squad machine gunners were equipped with PK machine guns as needed. As

3108-404: The Soviet Union , was a transcontinental country that spanned much of Eurasia from 1922 to 1991. During its existence, it was the largest country by area , extending across eleven time zones and sharing borders with twelve countries , and the third-most populous country . An overall successor to the Russian Empire , it was nominally organized as a federal union of national republics ,

3219-581: The Soviet republics , and the control of the Communist Party weakened. The failed coup attempt in August 1991 against Gorbachev by hardline communists hastened the end of the Soviet Union , which formally dissolved on December 26, 1991, ending nearly seven decades of Soviet rule. With an area of 22,402,200 square kilometres (8,649,500 sq mi), the Soviet Union was the world's largest country,

3330-772: The State Council , which functioned from 1810 to 1917, was referred to as a Council of Ministers. The Soviets as workers' councils first appeared during the 1905 Russian Revolution . Although they were quickly suppressed by the Imperial army, after the February Revolution of 1917 , workers' and soldiers' Soviets emerged throughout the country and shared power with the Russian Provisional Government . The Bolsheviks, led by Vladimir Lenin , demanded that all power be transferred to

3441-635: The Universal Declaration of Human Rights (1948), saying that it was "overly juridical" and potentially infringed on national sovereignty. The Soviet Union later signed legally-binding human rights documents, such as the International Covenant on Civil and Political Rights in 1973 (and the 1966 International Covenant on Economic, Social and Cultural Rights ), but they were neither widely known or accessible to people living under Communist rule, nor were they taken seriously by

3552-769: The largest arsenal of nuclear weapons in the world . As an Allied nation, it was a founding member of the United Nations as well as one of the five permanent members of the United Nations Security Council . Before its dissolution, the USSR was one of the world's two superpowers through its hegemony in Eastern Europe, global diplomatic and ideological influence (particularly in the Global South ), military and economic strengths, and scientific accomplishments. The word soviet

3663-485: The right to food , the right to work , and the right to education . The Soviet conception of human rights was very different from international law . According to Soviet legal theory , "it is the government who is the beneficiary of human rights which are to be asserted against the individual". The Soviet state was considered as the source of human rights. Therefore, the Soviet legal system considered law an arm of politics and it also considered courts agencies of

3774-703: The 1920s, it refused to rubber stamp proposals from the party and Council of Ministers. In 1990, Gorbachev introduced and assumed the position of the President of the Soviet Union , concentrated power in his executive office, independent of the party, and subordinated the government, now renamed the Cabinet of Ministers of the USSR , to himself. Tensions grew between the Union-wide authorities under Gorbachev, reformists led in Russia by Boris Yeltsin and controlling

3885-482: The 1950s, the Soviet Union expanded its efforts in space exploration and took a lead in the Space Race with the first artificial satellite , the first human spaceflight , the first space station , and the first probe to land on another planet . In 1985, the last Soviet leader, Mikhail Gorbachev , sought to reform the country through his policies of glasnost and perestroika . In 1989, various countries of

3996-601: The 1990s, people in the West were also interested in the radioactive hazards of nuclear facilities, decommissioned nuclear submarines , and the processing of nuclear waste or spent nuclear fuel . It was also known in the early 1990s that the USSR had transported radioactive material to the Barents Sea and Kara Sea , which was later confirmed by the Russian parliament.

With a 7.5 kg PKM general-purpose machine gun that weighed little more than the 4.8 kg RPK, the Soviets had little desire for the PU-21 or similar weapons. Since the rejection of the PU-21, the Russian military has not indicated any desire for

4218-526: The CPSU, being ruled directly by the union-wide party until 1990. Local authorities were organized likewise into party committees , local Soviets and executive committees . While the state system was nominally federal, the party was unitary. The state security police (the KGB and its predecessor agencies ) played an important role in Soviet politics. It was instrumental in the Red Terror and Great Purge , but

4329-616: The Chinese Type 56-1 variant). American firearm manufacturer DS Arms makes a semi-auto variant for civil market and a full-auto variant for export, both in the original design and also in a modernized version called RPD Carbine . The RPD Carbine has a fluted 17.5-inch barrel, modern front sight, alloy handguard with rails, M249 -type pistol grip and M4 recoil spring tube and buttstock. Because semi-auto RPD variants are manufactured using de- milled parts kits from full-auto RPD machine guns, in order to comply with ATF regulations

4440-529: The Communist authorities. Under Joseph Stalin , the death penalty was extended to adolescents as young as 12 years old in 1935. Sergei Kovalev recalled "the famous article 125 of the Constitution which enumerated all basic civil and political rights" in the Soviet Union. But when he and other prisoners attempted to use this as a legal basis for their abuse complaints, their prosecutor's argument

4551-538: The Politburo after the deaths of Lenin and Stalin, as well as after Khrushchev's dismissal, itself due to a decision by both the Politburo and the Central Committee. All leaders of the Communist Party before Gorbachev died in office, except Georgy Malenkov and Khrushchev, both dismissed from the party leadership amid internal struggle within the party. Between 1988 and 1990, facing considerable opposition, Mikhail Gorbachev enacted reforms shifting power away from

4662-518: The RPD remains in active service in many African and Asian nations. Apart from the former Soviet Union, the weapon was manufactured in China (as the Type 56 LMG ), Egypt (Maadi RPD ), North Korea ( Type 62 ) and, since 1956, Poland. The RPD is an automatic weapon using a gas-operated long-stroke piston system and a locking system recycled from previous Degtyaryov small arms , consisting of

4773-424: The RPK-74. The choice to keep it belt-fed only was made to lighten the weapon and make it less complex than a dual-feed model, allowing the troops in the field to top off spent belts as a trade-off for not accepting standard-issue assault rifle magazines. Aside from this, little is known about the RPL-20. The weapon is still in development, which Kalashnikov Concern predicts will take another 2–3 years. Despite

4884-644: The RPL-20. With an empty weight of 5.2-5.5 kg, the RPL-20 rivals the weight of an RPK-74 while providing belt-fed, open-bolt operation and quick-change barrels to enhance sustained fire. As of January 2024, Kalashnikov Concern completed preliminary tests of the RPL-20 machine gun, and Ministry of Defense of the Russian Federation plans to conduct State trials of the machine gun in 2024.

4995-736: The Russian Soviet Federative Socialist Republic (RSFSR), the world's first constitutionally socialist state . The revolution was not accepted by all within the Russian Republic , resulting in the Russian Civil War . The RSFSR and its subordinate republics were merged into the Soviet Union in 1922. Following Lenin's death in 1924, Joseph Stalin came to power, inaugurating rapid industrialization and forced collectivization that led to significant economic growth but contributed to

5106-475: The Russian name of the Soviet Union as СС has been taboo, the reason being that СС as a Russian Cyrillic abbreviation is associated with the infamous Schutzstaffel of Nazi Germany , as SS is in English. In English-language media, the state was referred to as the Soviet Union or the USSR. The Russian SFSR dominated the Soviet Union to such an extent that, for most of the Soviet Union's existence, it

5217-632: The Soviet Union and turned into SSRs, which was not recognized by most of the international community and was considered an illegal occupation . After the Soviet invasion of Finland , the Karelo-Finnish SSR was formed on annexed territory as a Union Republic in March 1940 and then incorporated into Russia as the Karelian ASSR in 1956. Between July 1956 and September 1991, there were 15 union republics (see map below). While nominally

5328-529: The Soviet Union . Boris Yeltsin , the leader of the RSFSR, oversaw its reconstitution into the Russian Federation , which became the Soviet Union's successor state; all other republics emerged as fully independent post-Soviet states . During its existence, the Soviet Union produced many significant social and technological achievements and innovations . It had the world's second-largest economy and largest standing military. An NPT-designated state , it wielded

5439-662: The Soviet Union's priorities changed. Despite previous conflict with the United Kingdom , Vyacheslav Molotov dropped his post war border demands. The Cold War was a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc , which began following World War II in 1945. The term cold war is used because there

5550-541: The Soviet Union's superpower status, the economy struggled due to its centralized nature, technological backwardness, and inefficiencies. The vast military expenditures and burdens of maintaining the Eastern Bloc, further strained the Soviet economy. In the 1980s, Mikhail Gorbachev 's policies of Glasnost (openness) and Perestroika (restructuring) aimed to revitalize the Soviet system but instead accelerated its unraveling. Nationalist movements gained momentum across

5661-546: The Soviet authorities admitted. The Soviet Union was the world's second largest producer of harmful emissions. In 1988, total emissions in the Soviet Union were about 79% of those in the United States. But since the Soviet GNP was only 54% of that of the United States, this means that the Soviet Union generated 1.5 times more pollution than the United States per unit of GNP.

5772-587: The Soviet military moved from the 7.62×39 mm round to the 5.45×39 mm cartridge for its rifles and light machine guns, it considered adopting a dual-feed light machine gun in the new caliber to replace the RPK, similar to the FN Minimi then being introduced in Western armies. This resulted in the development of the PU-21 light machine gun. The weapon was trialed, but rejected as being more complex and heavier than

5883-770: The Soviets, and gained support from the workers and soldiers. After the October Revolution , in which the Bolsheviks seized power from the Provisional Government in the name of the Soviets, Lenin proclaimed the formation of the Russian Socialist Federal Soviet Republic (RSFSR). During the Georgian Affair of 1922, Lenin called for the Russian SFSR and other national Soviet republics to form

5994-415: The Supreme Soviet were members of the CPSU. Of the party heads themselves, Stalin (1941–1953) and Khrushchev (1958–1964) were Premiers. Upon the forced retirement of Khrushchev, the party leader was prohibited from this kind of double membership, but the later General Secretaries for at least some part of their tenure occupied the mostly ceremonial position of Chairman of the Presidium of the Supreme Soviet ,

6105-551: The US led to the Cold War . The American-led Western Bloc coalesced into NATO in 1949, prompting the Soviet Union to form its own military alliance, the Warsaw Pact , in 1955. Neither side engaged in direct military confrontation, and instead fought on an ideological basis and through proxy wars . In 1953, following Stalin's death , the Soviet Union undertook a campaign of de-Stalinization under Nikita Khrushchev , which saw reversals and rejections of Stalinist policies. This campaign caused tensions with Communist China . During

6216-430: The USSR. Moscow eventually stopped threatening other states, and instead worked to open peaceful relationships in terms of trade, and diplomatic recognition. The United Kingdom dismissed the warnings of Winston Churchill and a few others about a continuing Marxist-Leninist threat, and opened trade relations and de facto diplomatic recognition in 1922. There was hope for a settlement of the pre-war Tsarist debts, but it

6327-409: The Warsaw Pact overthrew their Soviet-backed regimes , and nationalist and separatist movements erupted across the Soviet Union. In 1991, amid efforts to preserve the country as a renewed federation , an attempted coup against Gorbachev by hardline communists prompted the largest republics—Ukraine, Russia, and Belarus—to secede. On December 26, Gorbachev officially recognized the dissolution of

The Kola Peninsula was one of the places with major problems. Around the industrial cities of Monchegorsk and Norilsk , where nickel , for example, is mined, all forests have been destroyed by contamination, while the northern and other parts of Russia have been affected by emissions. During

6549-445: The bolt carrier and receiver. The RPD has a manually operated lever-type safety mechanism that secures the weapon against accidental firing by blocking the bolt catch when engaged. Unlike Degtyarov's earlier firearm patents, the RPD's return spring is located inside the butt. Like many other Russian-made firearms , the chamber and bore are chrome-lined , greatly decreasing the risk of corrosion and jamming . The weapon has

6660-453: The bolt carrier that are necessary for full-auto firing, such as the sear engagement surface, must be machined off during the semi-auto conversion process. Semi-auto RPD variants must also fire from a closed bolt, which requires the addition of a striker mechanism and other fire control group parts that are not found on full-auto RPD machine guns. Soviet Union The Union of Soviet Socialist Republics ( USSR ), commonly known as

6771-407: The chamber, the RPD uses a simpler "push through" design where the rounds are pushed out the front of the belt and into the chamber. At least three variants of the RPD belt were produced. The Russians and Hungarians both produced 50-round belt segments, while the Chinese produced 25-round belt segments. The Russian RPD belts held the rounds in place using the extractor groove. The Hungarians designed

The Russian, Hungarian, and Chinese RPD belts are all interchangeable, and can be linked together without affecting the feeding of the RPD. The combined belt segments are stored in a metal drum that is attached to a mount on the receiver, for

Although the RPD was ready for mass production during the final stages of World War II , it was adopted in 1948 and large scale delivery of

7104-429: The country was limited. The state restricted rights of citizens to private property . According to the Universal Declaration of Human Rights , human rights are the "basic rights and freedoms to which all humans are entitled." including the right to life and liberty , freedom of expression , and equality before the law ; and social, cultural and economic rights, including the right to participate in culture ,

Russia was now a pariah state, along with Germany. The two came to terms in 1922 with the Treaty of Rapallo that settled long-standing grievances. At the same time, the two countries secretly set up training programs for the illegal German army and air force operations at hidden camps in

7548-443: The face of the hammer strikes the rear of the firing pin. The mechanism is simple, rugged and reliable. It features a trigger mechanism that is limited to fully automatic fire only. The bolt is equipped with a spring-loaded casing extraction system , and a fixed insert inside the receiver housing which passes between the feed horns of the bolt serves as the ejector. Spent cartridge casings are ejected downward through an opening in

7659-466: The following tools and spare parts: pin punch (used for disassembling the bolt), cleaning jag, multi-tool (includes screwdriver, small and large wrenches used for adjusting the front sight and gas system, respectively, and a notch for installing and removing the cleaning jag on the cleaning rod), broken case extractor, front sight adjustment tool, gas tube scraping tool, gas port reamer, spare extractor, spare extractor spring, spare firing pin.

In 1924, during the national delimitation in Central Asia, Uzbekistan and Turkmenistan were formed from parts of Russia's Turkestan ASSR and two Soviet dependencies, the Khorezm and Bukharan PSPs . In 1929, Tajikistan was split off from the Uzbekistan SSR. With the constitution of 1936, the Transcaucasian SFSR

7881-481: The full-auto parts must be modified such that the resulting semi-auto rifle cannot be readily converted into a machine gun. Numerous machining operations are necessary to modify the de-milled full-auto RPD parts for use in a semi-auto RPD receiver. For example, the side rails on the bolt carrier must be machined to fit into the slots of the semi-auto receiver, which are purposefully made too narrow to accept an unmodified full-auto RPD bolt carrier. Additional portions of

In practice, the Soviet government significantly curbed the rule of law , civil liberties , protection of law and guarantees of property , which were considered as examples of "bourgeois morality" by Soviet law theorists such as Andrey Vyshinsky . The USSR and other countries in the Soviet Bloc had abstained from affirming

8325-466: The highest bodies of the party and making the Supreme Soviet less dependent on them. The Congress of People's Deputies was established, the majority of whose members were directly elected in competitive elections held in March 1989, the first in Soviet history. The Congress now elected the Supreme Soviet, which became a full-time parliament, and much stronger than before. For the first time since

8436-472: The implementation of socialist policies and the New Economic Policy (NEP), which allowed for market-oriented reforms. The rise of Joseph Stalin in the late 1920s ushered in an era of intense centralization and totalitarianism. Stalin's rule was characterized by the forced collectivization of agriculture , rapid industrialization , and the Great Purge , which eliminated perceived enemies of

8547-418: The issued cleaning kit is used to loosen the retaining bolt on the front sight clamp. The front sight can then be adjusted left or right for the correct windage, after which the retaining bolt is reinstalled to lock the sight into place. The rear sight is adjusted for elevation using a slider. The rear sight is marked in 100 meter increments from 100 to 1,000 meters. The rear sight is adjusted for windage using

8658-477: The largest and most populous of which was the Russian SFSR . In practice, its government and economy were highly centralized . As a one-party state governed by the Communist Party of the Soviet Union , it was a flagship communist state . Its capital and largest city was Moscow . The Soviet Union's roots lay in the October Revolution of 1917. The new government, led by Vladimir Lenin , established

8769-486: The most common Russian initialization is Союз ССР (transliteration: Soyuz SSR ) which essentially translates to Union of SSRs in English. In addition, the Russian short form name Советский Союз (transliteration: Sovyetsky Soyuz , which literally means Soviet Union ) is also commonly used, but only in its unabbreviated form. Since the start of the Great Patriotic War at the latest, abbreviating

8880-544: The new RPK-74, while still not providing squads with the boost in firepower a PK machine gun could provide. Meanwhile, a modernized development of the PK, the PKM, had been introduced. The PKM was lighter than its predecessor, at 7.5 kg, making it even easier to issue the weapon to squad machine gunners as necessary. In the US, there was a significant gap between the weight and firepower of

8991-417: The newly elected Supreme Soviet of the Russian SFSR , and communist hardliners. On 19–21 August 1991, a group of hardliners staged a coup attempt . The coup failed, and the State Council of the Soviet Union became the highest organ of state power 'in the period of transition'. Gorbachev resigned as General Secretary, only remaining President for the final months of the existence of the USSR. The judiciary

9102-400: The nominal head of state . The institutions at lower levels were overseen and at times supplanted by primary party organizations . However, in practice the degree of control the party was able to exercise over the state bureaucracy, particularly after the death of Stalin, was far from total, with the bureaucracy pursuing different interests that were at times in conflict with the party, nor

9213-608: The official Soviet system of importance (ground forces were second, Air Force fourth, and Navy fifth). The army had the greatest political influence. In 1989, there served two million soldiers divided between 150 motorized and 52 armored divisions. Until the early 1960s, the Soviet navy was a rather small military branch, but after the Caribbean crisis , under the leadership of Sergei Gorshkov , it expanded significantly. It became known for battlecruisers and submarines. In 1989, there served 500 000 men. The Soviet Air Force focused on

9324-544: The only legal party and the final policymaker in the country. At the top of the Communist Party was the Central Committee , elected at Party Congresses and Conferences. In turn, the Central Committee voted for a Politburo (called the Presidium between 1952 and 1966), Secretariat and the general secretary (First Secretary from 1953 to 1966), the de facto highest office in the Soviet Union. Depending on

9435-694: The other order until 1936 . In addition, in the regional languages of several republics, the word council or conciliar in the respective language was only quite late changed to an adaptation of the Russian soviet and never in others, e.g. Ukrainian SSR . СССР (in the Latin alphabet: SSSR ) is the abbreviation of the Russian-language cognate of USSR, as written in Cyrillic letters . The Soviets used this abbreviation so frequently that audiences worldwide became familiar with its meaning. After this,

9546-570: The partition of Poland. In response, Britain and France declared war on Germany, marking the beginning of World War II . Up until his death in 1953, Joseph Stalin controlled all foreign relations of the Soviet Union during the interwar period . Despite the increasing build-up of Germany 's war machine and the outbreak of the Second Sino-Japanese War , the Soviet Union did not cooperate with any other nation, choosing to follow its own path. However, after Operation Barbarossa ,

9657-538: The party's highest body the Politburo . Operations were handled by the separate Ministry of Foreign Affairs . It was known as the People's Commissariat for Foreign Affairs (or Narkomindel), until 1946. The most influential spokesmen were Georgy Chicherin (1872–1936), Maxim Litvinov (1876–1951), Vyacheslav Molotov (1890–1986), Andrey Vyshinsky (1883–1954) and Andrei Gromyko (1909–1989). Intellectuals were based in

9768-403: The rear sight was moved to the left side of the notch. Later, the RPD was modified with a non-reciprocating cocking mechanism with a folding charging handle (replacing the fixed charging handle connected to the bolt carrier) that does not move during firing. The feed port received a dust cover, which when open, serves as a feeding ramp for the ammunition belt. This version of the light machine gun

9879-439: The receiver) to accept an NSP-2 night vision sight . Standard accessories issued with the weapon include a sling , extra ammunition drums and belts (with either belt or shoulder pouches for same), oil bottle , cleaning rod (carried in a slot on the left side of the receiver), (stowed in a compartment inside the stock), and drop case. The cleaning kit consists of a rectangular metal clam-shell case that typically contains

9990-594: The state. The Soviet Union played a crucial role in the Allied victory in World War II , but at a tremendous human cost, with millions of Soviet citizens perishing in the conflict. The Soviet Union emerged as one of the world's two superpowers, leading the Eastern Bloc in opposition to the Western Bloc during the Cold War . This period saw the USSR engage in an arms race, the Space Race , and proxy wars around

10101-469: The struggle for dominance was expressed via indirect means such as psychological warfare , propaganda campaigns, espionage , far-reaching embargoes , rivalry at sports events and technological competitions such as the Space Race . Constitutionally, the USSR was a federation of constituent Union Republics, which were either unitary states, such as Ukraine or Byelorussia (SSRs), or federations, such as Russia or Transcaucasia (SFSRs), all four being

10212-492: The truth". Human rights in the Soviet Union were severely limited. The Soviet Union was a totalitarian state from 1927 until 1953 and a one-party state until 1990. Freedom of speech was suppressed and dissent was punished. Independent political activities were not tolerated, whether these involved participation in free labour unions , private corporations , independent churches or opposition political parties . The freedom of movement within and especially outside

10323-639: The weapon did not begin until 1953. During the Vietnam War , the RPD and its Chinese copy (Type 56) served the Viet Cong and the People's Army of Vietnam as their standard light machine gun. After the introduction of the Kalashnikov -pattern support weapons, such as the RPK and PK machine guns in the 1960s, the RPD was withdrawn from most first-tier units of the former Warsaw Pact . However,

10434-478: The weapon's developmental nature, Kalashnikov Concern has provided video of the weapon being handled and fired, demonstrating that they have at least completed a fully-functioning prototype. Russian (at the time Soviet) military forces have not fielded a squad-level, intermediate caliber, belt-fed machine gun since the retirement of the RPD in the early 1960s. Official Soviet doctrine from the 1960s onward dictated that squad-level suppressive fire would be provided by

10545-527: The west further raised concerns. In the past, there were accidents involving submarines K-19 , K-8 , a K-129 , K-27 , K-219 and K-278 Komsomolets . There were three power hierarchies in the Soviet Union: the legislature represented by the Supreme Soviet of the Soviet Union , the government represented by the Council of Ministers , and the Communist Party of the Soviet Union (CPSU),

10656-465: The world's largest lakes; the Caspian Sea (shared with Iran ), and Lake Baikal , the world's largest (by volume) and deepest freshwater lake that is also an internal body of water in Russia. Neighbouring countries were aware of the high levels of pollution in the Soviet Union but after the dissolution of the Soviet Union it was discovered that its environmental problems were greater than what

10767-510: Was a coastline . The country bordered Afghanistan , the People's Republic of China , Czechoslovakia , Finland , Hungary , Iran , Mongolia , North Korea , Norway , Poland , Romania , and Turkey from 1945 to 1991. The Bering Strait separated the USSR from the United States . The country's highest mountain was Communism Peak (now Ismoil Somoni Peak ) in Tajikistan , at 7,495 metres (24,590 ft). The USSR also included most of

10878-539: Was also the industrial center of the Soviet Union. Historian Matthew White wrote that it was an open secret that the country's federal structure was 'window dressing' for Russian dominance. For that reason, the people of the USSR were usually called 'Russians', not 'Soviets', since 'everyone knew who really ran the show'. Under the Military Law of September 1925, the Soviet Armed Forces consisted of

10989-483: Was brought under strict party control after Stalin's death. Under Yuri Andropov , the KGB engaged in the suppression of political dissent and maintained an extensive network of informers, reasserting itself as a political actor to some extent independent of the party-state structure, culminating in the anti-corruption campaign targeting high-ranking party officials in the late 1970s and early 1980s. The constitution , which

11100-540: Was carried out within the terms of the Soviet Civil Code. Some Soviet legal scholars even said that "criminal repression" may be applied in the absence of guilt. Martin Latsis , chief of Soviet Ukraine 's secret police explained: "Do not look in the file of incriminating evidence to see whether or not the accused rose up against the Soviets with arms or words. Ask him instead to which class he belongs, what

11211-475: Was colloquially, but incorrectly, referred to as Russia . The history of the Soviet Union began with the ideals of the Bolshevik Revolution and ended in dissolution amidst economic collapse and political disintegration. Established in 1922 following the Russian Civil War , the Soviet Union quickly became a one-party state under the Communist Party . Its early years under Lenin were marked by

11322-404: Was dissolved, resulting in its constituent republics of Armenia , Georgia and Azerbaijan being elevated to Union Republics, while Kazakhstan and Kirghizia were split off from the Russian SFSR, resulting in the same status. In August 1940, Moldavia was formed from parts of Ukraine and Soviet-occupied Bessarabia , and Ukrainian SSR. Estonia , Latvia and Lithuania were also annexed by

11433-424: Was no large-scale fighting directly between the two superpowers , but they each supported major regional conflicts known as proxy wars . The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany in 1945. Aside from the nuclear arsenal development and conventional military deployment,

11544-450: Was not independent of the other branches of government. The Supreme Court supervised the lower courts ( People's Court ) and applied the law as established by the constitution or as interpreted by the Supreme Soviet. The Constitutional Oversight Committee reviewed the constitutionality of laws and acts. The Soviet Union used the inquisitorial system of Roman law , where the judge, procurator , and defence attorney collaborate to "establish

11655-458: Was produced mainly in China and Poland. A further modified variant (sometimes referred to as the RPDM ) includes an extended gas cylinder and a recoil buffer mechanism in the stock. Late production RPD variants also had the fixed drum attachment removed (instead, the ammunition container was "hung" from the feed port cover) and feature a folding cleaning rod, that is stored in the weapon's butt (in

11766-485: Was promulgated in 1924 , 1936 and 1977 , did not limit state power. No formal separation of powers existed between the Party, Supreme Soviet and Council of Ministers that represented executive and legislative branches of the government. The system was governed less by statute than by informal conventions, and no settled mechanism of leadership succession existed. Bitter and at times deadly power struggles took place in

11877-477: Was repeatedly postponed. Formal recognition came when the new Labour Party came to power in 1924. All the other countries followed suit in opening trade relations. Henry Ford opened large-scale business relations with the Soviets in the late 1920s, hoping that it would lead to long-term peace. Finally, in 1933, the United States officially recognized the USSR, a decision backed by the public opinion and especially by US business interests that expected an opening of

11988-482: Was that "the Constitution was written not for you, but for American Negroes, so that they know how happy the lives of Soviet citizens are". Crime was determined not as the infraction of law, instead, it was determined as any action which could threaten the Soviet state and society. For example, a desire to make a profit could be interpreted as a counter-revolutionary activity punishable by death. The liquidation and deportation of millions of peasants in 1928–31

12099-587: Was the Russian responsibility to assist them. The Comintern was the weapon of choice. A few revolutions did break out, but they were quickly suppressed (the longest lasting one was in Hungary)—the Hungarian Soviet Republic —lasted only from 21 March 1919 to 1 August 1919. The Russian Bolsheviks were in no position to give any help. By 1921, Lenin, Trotsky, and Stalin realized that capitalism had stabilized itself in Europe and there would not be any widespread revolutions anytime soon. It became

12210-404: Was the first major accident at a civilian nuclear power plant . Unparalleled in the world, it resulted in a large number of radioactive isotopes being released into the atmosphere. Radioactive doses were scattered relatively far. Although long-term effects of the accident were unknown, 4,000 new cases of thyroid cancer which resulted from the accident's contamination were reported at the time of

12321-486: Was the party itself monolithic from top to bottom, although factions were officially banned . The Supreme Soviet (successor of the Congress of Soviets ) was nominally the highest state body for most of the Soviet history, at first acting as a rubber stamp institution, approving and implementing all decisions made by the party. However, its powers and functions were extended in the late 1950s, 1960s and 1970s, including
