Soviet Army in the context of "KGB"

Between 28 June and 3 July 1940, the Soviet Union occupied Bessarabia and Northern Bukovina, following an ultimatum made to Romania on 26 June 1940 that threatened the use of force. Those regions, with a total area of 50,762 km (19,599 sq mi) and a population of 3,776,309 inhabitants, were incorporated into the Soviet Union. On 26 October 1940, six Romanian islands on the Chilia branch of the Danube, with an area of 23.75 km (9.17 sq mi), were also occupied by the Soviet Army.

The Soviet Union had planned to accomplish the annexation with a full-scale invasion, but the Romanian government, responding to the Soviet ultimatum delivered on 26 June, agreed to withdraw from the territories to avoid a military conflict. The use of force had been made illegal by the Conventions for the Definition of Aggression in July 1933, but from an international legal standpoint, the new status of the annexed territories was eventually based on a formal agreement through which Romania consented to the retrocession of Bessarabia and cession of Northern Bukovina. As it was not mentioned in the ultimatum, the annexation of the Hertsa region was not consented to by Romania, and the same is true of the subsequent Soviet occupation of the Danube islands. On 24 June, Nazi Germany, which had acknowledged the Soviet interest in Bessarabia in a secret protocol to the 1939 Molotov–Ribbentrop Pact, had been made aware prior to the planned ultimatum but did not inform the Romanian authorities and was unwilling to provide support. On 22 June, France, a guarantor of Romanian borders, fell to Nazi advances. This is considered to be an important factor in the Soviets' decision to issue the ultimatum. The Soviet invasion of Bukovina in 1940 violated the Molotov-Ribbentrop Pact, since it went beyond the Soviet sphere of influence that had been agreed with the Axis.

The Workers' and Peasants' Red Army, often referred by its shortened name as the Red Army, was the army and air force of the Russian Soviet Republic and, from 1922, the Soviet Union. The army was established in January 1918 by a decree of the Council of People's Commissars to oppose the military forces of the new nation's adversaries during the Russian Civil War, especially the various groups collectively known as the White Army. In February 1946, the Red Army (which embodied the main component of the Soviet Armed Forces alongside the Soviet Navy) was renamed the "Soviet Army". Following the dissolution of the Soviet Union it was split between the post-Soviet states, with its bulk becoming the Russian Ground Forces, commonly considered to be the successor of the Soviet Army.

The Red Army provided the largest ground force in the Allied victory in the European theatre of World War II, and its invasion of Manchuria assisted the unconditional surrender of Japan. During its operations on the Eastern Front, it accounted for 75–80% of the casualties that the Wehrmacht and Waffen-SS suffered during the war, and ultimately captured the German capital, Berlin.

The Great Patriotic War is a term used in Russia (and formerly the Soviet Union) and some other post-Soviet states to describe the Eastern Front of World War II, fought primarily between the Soviet Union and Nazi Germany between 22 June 1941 and 9 May 1945. For some legal purposes, this period may be extended to 11 May 1945 to include the end of the Prague offensive.

The second Jassy–Kishinev offensive, named after the two major cities, Jassy and Kishinev, in the staging area, was a Soviet offensive against Axis forces, which took place in Eastern Romania from 20 to 29 August 1944 during World War II. The 2nd and 3rd Ukrainian Fronts of the Red Army engaged Army Group South Ukraine, which consisted of combined German and Romanian formations, in an operation to reoccupy Bessarabia and destroy the Axis forces in the region, opening the way into Romania and the Balkans.

The offensive resulted in the encirclement and destruction of the German forces, allowing the Soviet Army to resume its strategic advance further into Eastern Europe. It also pressured Romania to switch allegiance from the Axis powers to the Allies. For the Germans, this was a massive defeat, which can be compared to the defeat at Stalingrad.

The Ukrainian Ground Forces (SVZSU, Ukrainian: Сухопутні війська Збройних сил України, СВЗСУ, romanized: Sukhoputni viiska Zbroinykh syl Ukrainy), also referred to as the Ukrainian army, is a land force, and one of the eight branches of the Armed Forces of Ukraine. It was formed from Ukrainian units of the Soviet Army after Ukrainian independence, and its ancestry is traced back to the 1917–22 army of the Ukrainian People's Republic.

After the dissolution of the Soviet Union in 1991, Ukraine retained its Soviet-era army equipment. The Armed Forces were systematically downsized and underinvested in after 1991. As a result, the Ukrainian army had very little of its Soviet equipment in working order by July 2014, and most systems had become antiquated. Personnel numbers had shrunk and training, command, and support functions needed improvement. After the start of the war in Donbas in April 2014 in eastern Ukraine, Ukraine embarked on a program to enlarge and modernise its armed forces. Personnel in the Ukrainian Armed Forces overall climbed from 129,950 in March 2014 to 204,000 active personnel in May 2015, with 169,000 soldiers in the Ground Forces branch as of 2016. In 2016, 75% of the army consisted of contract servicemen. Since 2014, Ukraine's ground forces have also been equipped with increasingly modern tanks, APCs, and many other types of combat equipment.

The Western Group of Forces (WGF), previously known as the Group of Soviet Occupation Forces in Germany (GSOFG) and the Group of Soviet Forces in Germany (GSFG) were the troops of the Soviet Army in East Germany. The Group of Soviet Occupation Forces in Germany was formed after the end of World War II in Europe from units of the 1st and 2nd Belorussian Fronts. The group helped suppress the East German uprising of 1953. After the end of occupation functions in 1954 the group was renamed the Group of Soviet Forces in Germany. The group represented Soviet interests in East Germany during the Cold War. Before changes in Soviet foreign policy during the early 1990s, the group shifted to a more offensive role and in 1989 became the Western Group of Forces. They remained in the eastern part of Germany after the dissolution of the Soviet Union and German reunification until 1994.

The Armed Forces of the Union of Soviet Socialist Republics, also known as the Armed Forces of the Soviet Union, the Red Army (1918–1946) and the Soviet Army (1946–1991), were the armed forces of the Communist Party of the Soviet Union (CPSU), Russian Soviet Federative Socialist Republic (1917–1922) and the Soviet Union (1922–1991) from their beginnings in the Russian Civil War of 1917–1923 to the collapse of the Soviet Union in 1991. In May 1992, Russian president Boris Yeltsin issued decrees forming the Russian Armed Forces, which subsumed much of the Soviet Armed Forces. Multiple sections of the former Soviet Armed Forces in the other, smaller Soviet republics gradually came under those republics' control.

According to the all-union military service law of September 1925, the Soviet Armed Forces consisted of the Red Army, the Air Forces, the Navy, the State Political Directorate (OGPU), and the convoy guards. The OGPU was later made independent and amalgamated with the NKVD in 1934, and thus its Internal troops were under the joint management of the Defence and Interior Commissariats. In 1989, the Soviet Armed Forces consisted of the Strategic Rocket Forces, the Ground Forces, the Air Defence Forces, the Air Forces, and the Navy, listed in their official order of importance.

The AK-47, officially known as the Avtomat Kalashnikova (Russian: Автомат Калашникова, lit. 'Kalashnikov's automatic [rifle]'; also known as the Kalashnikov or just AK), is an assault rifle that is chambered for the 7.62×39mm cartridge. Developed in the Soviet Union by Russian small-arms designer Mikhail Kalashnikov, it is the originating firearm of the Kalashnikov (or "AK") family of rifles. After more than seven decades since its creation, the AK-47 model and its variants remain one of the most popular and widely used firearms in the world.

Design work on the AK-47 began in 1945. It was presented for official military trials in 1947, and, in 1948, the fixed-stock version was introduced into active service for selected units of the Soviet Army. In early 1949, the AK was officially accepted by the Soviet Armed Forces and used by the majority of the member states of the Warsaw Pact.
