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
1935-516: A new version with enhanced fighting capabilities, the BMP-2 , was introduced in 1980. It had a new two-man turret armed with a 30 mm 2A42 multi-purpose autocannon and a 9P135M-1 ATGM launcher capable of firing SACLOS guided 9M113 Konkurs and 9M113M Konkurs-M as well as 9M111 and 9M111-2 Fagot ATGMs. Later modernization plans included mounting the turret of the BMD-2 IFV on to BMP-1s, but

The commander's station is equipped with an R-123M radio set. The BMP-1 has a conical turret equipped with
2322-417: A tandem shaped-charge or high-explosive thermobaric warhead . The BMP-1 was a threat to NATO APCs, light AFVs, and even MBTs of its time, by use of its main gun or ATGM. Nevertheless, the strong anti-tank focus of its armament didn't provide sufficient firepower against enemy unarmored vehicles, infantry and light fortified positions, especially during mountain battles (mostly due to the low elevation angle of
2451-475: 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

The 2A28 'Grom' smoothbore gun fires the same PG-15V projectiles as the SPG-9 infantry light recoilless gun, but with a smaller propellant charge. The PG-15V HEAT warhead can penetrate 280 to 350 mm (11 to 14 in) of steel armor – more than enough to penetrate
9417-421: The center line of the vehicle and face the sides. Vehicle batteries, electric equipment and the main 330 L (73 imp gal; 87 US gal) fuel tank are located between the benches, with tool stowage beneath. There are four large D-shaped hatches in the roof of the hull, which can be opened from the troop compartment. The airtight rear doors of the troop compartment contain fuel tanks. Space inside
9546-514: The command of Guards Major Vasiliy Samodelov. Small-scale production began in 1966. The BMP went into production with the Soviet Army in 1966. The first series (Ob'yekt 765 Sp1, "specification 1") was produced until 1969. It was replaced by the improved production model, the BMP-1 (the Ob'yekt 765 Sp2), which was produced from 1969 until 1973. This, in turn, was replaced by the Ob'yekt 765 Sp3, which
9675-506: The commander's and driver's seats for added protection against mines. It had large steel armored skirts fitted to the sides of the hull covering the suspension. Firing ports were added into the top hatches of the troop compartment and a stowage box was placed on the roof at the rear of the hull on some vehicles. The 9S428 ATGM launcher was often removed and replaced by an AGS-17 automatic grenade launcher. Due to experience in Afghanistan,
9804-429: 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 ,
9933-660: The country's area and was the cultural and economic center. The eastern part in Asia extended to 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
10062-553: The duty of the Russian Bolsheviks to protect what they had in Russia, and avoid military confrontations that might destroy their bridgehead. 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
10191-659: The forced collectivization of agriculture , rapid industrialization , and the Great Purge , which eliminated perceived enemies of 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
10320-779: The founding republics who signed the Treaty on the Creation of the USSR in December 1922. 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
10449-423: The frontal arc, as well as from light shell fragments at distances between 500 m and 800 m. Firepower consisted of the innovative combination of the 73 mm 2A28 Grom gun and a launcher for the 9M14 Malyutka (AT-3A Sagger A) anti-tank wire-guided missile (ATGM). The gun was intended to engage enemy armored vehicles and firing points at a range of up to 700 metres (770 yd). The missile launcher
10578-623: The frontal armor of NATO MBTs of the 1970s, such as the US M60A1 , the British Chieftain or the German Leopard 1 . The modernized PG-9 shell is able to penetrate up to 400 mm (16 in) of steel armor. Under battlefield conditions, it has a maximum effective range of 500 m (550 yd). The disadvantage of the BMP-1 is the small elevation angle of the gun (only 15 degrees). OG-15V high explosive ammunition
10707-549: The government. Extensive extrajudicial powers were given to the Soviet secret police agencies . 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
10836-523: 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 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
10965-454: 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
11094-603: 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 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
11223-472: The largely ineffective 9M14M Malyutka ATGM with the more reliable, longer range and more powerful 9P135M or 9P135M-1 ATGM launcher. It was located on a special pintle mount on top of the turret roof, that could fire the SACLOS guided 9M113 and 9M113M Konkurs-M ATGMs, which increased armor penetration to 670 mm (26 in) and had an extended range of 4,000 m (4,400 yd). The 9P135M-1 launcher
11352-611: The late 1950s, 1960s and 1970s, including the creation of new state commissions and committees. It gained additional powers relating to the approval of the Five-Year Plans and the government budget . The Supreme Soviet elected a Presidium (successor of the Central Executive Committee ) to wield its power between plenary sessions, ordinarily held twice a year, and appointed the Supreme Court ,
11481-546: The late 1970s and early 1980s. The constitution , which 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
11610-400: The launcher. Each 9M14M weighs 10.9 kg (24 lb), a 9M14P is 11.4 kg (25 lb). These missiles can only be fired in daylight because of the lack of a night sight. A guidance device used in the BMP-1 has the code 9S428. Besides possessing such advantages as interference immunity and simple control equipment, wire-guided ATGMs are also hampered by significant disadvantages such as
11739-517: The long, pointed nose can give some problems when crossing large trenches. The fuel tanks have a maximum capacity of 462 litres (102 imp gal). The diesel engine is of a multifuel design and can use DL (summer) or DZ (winter). It can also use TS-1 kerosene. The BMP-1 has a maximum road speed of 65 kilometres per hour (40 mph), which is automatically reduced to around 45 kilometres per hour (28 mph) off-road. The BMP-1 can climb 70-centimetre (28 in) high vertical obstacles, and cross
11868-483: The main gun). The appearance of the more successful BMP-2 armed with the 30mm 2A42 dual-purpose autocannon solved this serious problem. The troop compartment located at the rear of the vehicle can carry up to eight soldiers. There are four firing ports on each side of the vehicle and a single firing port in the left rear door. A combination fume extractor hose and cartridge deflector is provided to clip on to weapons at each station. Soldiers sit on two padded benches along
11997-526: The mostly ceremonial position of Chairman of the Presidium of the Supreme Soviet , 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
12126-410: The name to the Union of Soviet Socialist Republics (USSR), although all republics began as socialist soviet and did not change to 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
12255-417: 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
12384-608: 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
12513-499: The other constituent republics, for most of its history had no republican branch of 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
12642-436: The other from 400 to 1,300 metres (440 to 1,420 yd). The main armament is the 73 mm 2A28 "Grom" low pressure smoothbore semi-automatic gun. It is fed from a 40-round magazine located around the turret ring. The cyclic rate of fire is 8 to 10 rounds per minute. The gun returns to an elevation of +3° 30' to reload after each shot if the autoloader is used. The gun can be reloaded by hand if necessary. Some units removed
12771-570: 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 ,
12900-538: 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
13029-459: The party, nor 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
13158-469: 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
13287-692: 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 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 ,
13416-417: The time). The 9M14P missile can be used in manual mode only, like older missiles, without the advantage of semi-automatic guidance. The BMP-1 carries four ATGMs with their launching rails as a standard (two inside the turret and two inside the hull). In theory, a fifth missile can be carried on the launcher. The missiles are loaded onto a rail launcher through a small rectangular hatch in a turret's roof behind
13545-494: The troop compartment is limited. There is little room for personal equipment, which leads to it being stowed outside while on operation, sometimes limiting rearward traverse of the turret. The seating is cramped, especially for troops in full battle dress. In the BMP-1 and BMP-2, ammunition is stored near or even inside the compartment, which can lead to a catastrophic failure in case of a hull breach. The 300 horsepower (224 kW) UTD-20 six-cylinder four-stroke diesel engine
13674-492: 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
13803-452: The turret is unstabilised. Mounted on the gun mantlet, the ATGM launcher is capable of firing the 9M14 Malyutka , (NATO: AT-3A Sagger A), the 9M14M Malyutka-M (NATO: AT-3B Sagger B) and the 9M14P Malyutka-P (NATO: AT-3C Sagger C). All are intended to be used against enemy MBTs and other AFVs at distances from 500 to 3,000 m (550 to 3,280 yd). These ATGMs can penetrate up to 400 mm (16 in) of steel armor (NATO standard at
13932-500: The use of the infra-red searchlight. The sight is marked stadiametricly with the apparent size of a 2.7 metres (8.9 ft) tall tank at various ranges. The original sight was replaced with the 1PN22M2, which has an additional scale for the OG-15V HE-Frag rounds used by the Ob'yekt 765Sp3, produced from July 1974. The new sight has two day scales for the two projectiles – one from 200 to 1,600 metres (220 to 1,750 yd) and
14061-438: The vehicle never left the design phase. Recent proposals for the modernization of BMP-1s include mounting new turrets armed with a 2A72 30 mm (1.2 in) autocannon, approved in 2018, or a TKB-799 Kliver one-man weapons station with a computerized fire control system, armed with a missile pod (which can be armed with either four 9M133 Kornet (AT-14 Spriggan) or 9M133F Kornet ATGMs or 9K38 Igla (SA-18 Grouse) SAMs),
14190-434: The water, the trim vane at the front of the hull should be erected to prevent water from flooding over the bow. While in its travelling position, it serves as additional frontal armor. The rear doors of the troop compartment must be closed tightly before entering the water. Before entering the water, either a full crew of eight troopers or an equivalent ballast must be present in the rear of the vehicle, otherwise vehicle balance
14319-403: The world's longest border , measuring over 60,000 kilometres (37,000 mi), or 1 + 1 ⁄ 2 circumferences of Earth. Two-thirds of it 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
14448-587: Was Moscow . The Soviet Union's roots lay in the October Revolution of 1917. The new government, led by Vladimir Lenin , established 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
14577-471: Was a modernized, 200 kg heavier version that was produced from 1973 to 1979. A number of improvements were made to the reliability of the chassis, engine and transmission during mass production. The latest version of the BMP-1 IFV (BMP-1P, Ob'yekt 765 Sp4), which was produced from 1979 to 1983, was armed with a more powerful ATGM launcher 9P135M-1 for the ATGM "Konkurs"/"Fagot". The main manufacturer of
14706-539: 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
14835-445: Was capable of firing 9M111 and 9M111-2 Fagot ATGMs. The Malyutka loading hatch was usually welded shut and the mounting bracket was removed. The new missiles were somewhat difficult to use since the gunner had to stand in his open hatch, exposing himself to hostile fire. It is possible to detach the 9P135M(1) ATGM launcher from the turret and use it from the ground. The BMP-1P was equipped with neutron weapon protection covering and
14964-540: 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
15093-585: Was chosen because its front-engine design provided a convenient and fast way of mounting and dismounting through two rear doors. The original prototype was built in 1964, followed by the improved Ob'yekt 765 in 1965, which was accepted by the Army in 1966, under a designation BMP-1. The 120th Guards Motor Rifle Division was the first formation in the Soviet Union to test prototypes of the new BMP ("objekt 765") infantry fighting vehicle in January–November 1965, under
15222-404: 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
15351-604: Was first tested in combat in the 1973 Yom Kippur War , where it was used by Egyptian and Syrian forces. Based on lessons learned from this conflict, and early experiences in the Soviet–Afghan War , a version with improved fighting qualities was developed, the BMP-2 . It was accepted into service in August 1980. In 1987, the BMP-3 , a radically redesigned vehicle with a completely new weapon, entered service in limited numbers with
15480-483: Was instrumental in the Red Terror and Great Purge , but 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
15609-413: Was intended to be used against targets that were 500 metres (550 yd) to 3,000 metres (3,300 yd) away. Requirements were issued to the various design bureaus between 1959 and 1960. There was a question as to whether the BMP should be tracked or wheeled, so a number of experimental configurations were explored, including hybrid wheeled/tracked designs. The tracked Ob'yekt 764 (codename Object 764)
15738-559: Was known. The Soviet military leadership saw any future wars as being conducted with nuclear, chemical and biological weapons. A new design, like the BMP, combining the properties of an armoured personnel carrier (APC) and a light tank would allow infantry to operate from the relative safety of its armoured, radiation-shielded interior in contaminated areas and to fight alongside it in uncontaminated areas. It would increase infantry squad mobility, provide fire support to them, and also be able to fight alongside main battle tanks . The BMP-1
15867-420: Was made available from 1974. The warhead has twice the weight of explosives as the anti-armor PG-15V. It is intended for use against troops or soft targets . A coaxial 7.62 mm PKT machine gun is mounted to the right of the main armament for which the BMP-1 carries 2,000 rounds. The 2A28 'Grom' gun and PKT coaxial machine gun cannot be accurately fired while the vehicle is on the move over rough ground as
15996-424: 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,
16125-450: 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
16254-459: 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. The Soviet Chernobyl disaster in 1986 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
16383-477: 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
16512-482: 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
16641-640: 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
