KV-1
The Kliment Voroshilov (KV) tanks are a series of Soviet heavy tanks named after the Soviet defence commissar and politician Kliment Voroshilov who operated with the Red Army during World War II. The KV tanks were known for their heavy armour protection during the early stages of the war, especially during the first year of the German invasion of the Soviet Union. In certain situations, even a single KV-1 or KV-2 supported by infantry could halt German formations. The German ''Wehrmacht'' at that time rarely deployed its tanks against KVs, as their own armament was too poor to deal with the "''Russischer Koloss''" – "Russian Colossus". The KV tanks were practically immune to the 3.7 cm KwK 36 and howitzer-like, short-barreled 7.5 cm KwK 37 guns mounted, respectively, on the early Panzer III and Panzer IV tanks fielded by the invading German forces. Until the Germans developed more effective guns, the KV-1 was invulnerable to almost any German weapon except the 8.8 cm Flak gun. ...

Panzer IV
The ''Panzerkampfwagen'' IV (Pz.Kpfw. IV), commonly known as the ''Panzer'' IV, was a German medium tank developed in the late 1930s and used extensively during the Second World War. Its ordnance inventory designation was Sd.Kfz. 161. The Panzer IV was the most numerous German tank and the second-most numerous German fully tracked armoured fighting vehicle of the Second World War; 8,553 Panzer IVs of all versions were built during World War II, only exceeded by the StuG III assault gun with 10,086 vehicles. Its chassis was also used as the base for many other fighting vehicles, including the Sturmgeschütz IV assault gun, the Jagdpanzer IV self-propelled anti-tank gun, the ''Wirbelwind'' self-propelled anti-aircraft gun, and the '' Brummbär'' self-propelled gun. The Panzer IV saw service in all combat theatres involving Germany and was the only German tank to remain in continuous production throughout the war. It was originally designed for infantry support, while the sim ...

Tanks In The Soviet Union
This article deals with the history and development of tanks of the Soviet Union and its successor state Russian Federation from their first use after World War I, into the interwar period, during World War II, the Cold War and modern era. Overview After World War I, many nations needed to have tanks, but only a few had the industrial resources to design and build them. During and after World War I, Britain and France were the intellectual leaders in tank design, with other countries generally following and adopting their designs. This early lead would be gradually lost during the course of the 1930s to the Soviet Union who with Germany began to design and build their own tanks. The Treaty of Versailles had severely limited Germany's industrial output. Therefore, in order to circumvent Germany's treaty restrictions, these industrial firms formed a partnership with the Soviet Union to legally produce weapons and sell them, and along with other factors built up an infrastructure to ...

T-34
The T-34 is a Soviet medium tank introduced in 1940. When introduced its 76.2 mm (3 in) tank gun was less powerful than its contemporaries while its 60-degree sloped armour provided good protection against Anti-tank warfare, anti-tank weapons. The Christie suspension was inherited from the design of American J. Walter Christie's M1928 tank, versions of which were sold turret-less to the Red Army and documented as "farm tractors", after being rejected by the U.S. Army. The T-34 had a profound effect on the conflict on the Eastern Front (World War II), Eastern Front in the World War II, Second World War, and had a short lasting impact on tank design. After the Germans encountered the tank in 1941 during Operation Barbarossa, German general Paul Ludwig Ewald von Kleist called it "the finest tank in the world" and Heinz Guderian affirmed the T-34's "vast superiority" over German tanks. Alfred Jodl, chief of operations staff of the German armed forces noted in his war diar ...

Red Army
The Workers' and Peasants' Red Army (Russian: Рабо́че-крестья́нская Кра́сная армия),) often shortened to the Red Army, was the army and air force of the Russian Soviet Federative Socialist Republic and, after 1922, the Union of Soviet Socialist Republics. The army was established in January 1918. The Bolsheviks raised an army to oppose the military confederations (especially the various groups collectively known as the White Army) of their adversaries during the Russian Civil War. Starting in February 1946, the Red Army, along with the Soviet Navy, embodied the main component of the Soviet Armed Forces; taking the official name of "Soviet Army", until its dissolution in 1991. The Red Army provided the largest land force in the Allied victory in the European theatre of World War II, and its invasion of Manchuria assisted the unconditional surrender of Imperial Japan. During operations on the Eastern Front, it accounted for 75–80% of casual ...

Heavy Tank
Heavy tank is a term used to define a class of tanks produced from World War I through the end of the Cold War. These tanks generally sacrificed mobility and maneuverability for better armour protection and equal or greater firepower than tanks of lighter classes. Role Heavy tanks achieved their greatest, albeit limited, success when fighting lighter tanks and destroying fortifications. Heavy tanks often saw limited combat in their intended roles, instead becoming mobile pillboxes or defensive positions, such as the German Tiger designs, or the Russian KV designs Design Heavy tanks feature very heavy armor and weapons relative to lighter tanks. Many heavy tanks shared components from lighter tanks. For example, the M103 heavy tank shared many components with lighter Patton tanks, including transmission and engine. As a result, they tend to be either underpowered and comparatively slow, or have engine and drive train reliability issues. In case of an entirely new design deve ...

Panzer III
The ''Panzerkampfwagen III'', commonly known as the Panzer III, was a medium tank developed in the 1930s by Germany, and was used extensively in World War II. The official German ordnance designation was Sd.Kfz. 141. It was intended to fight other armoured fighting vehicles and serve alongside and support the similar Panzer IV, which was originally designed for infantry support. However, as the Germans faced the formidable T-34, more powerful anti-tank guns were needed, and since the Panzer IV had more development potential with a larger turret ring, it was redesigned to mount the long-barrelled 7.5 cm KwK 40 gun. The Panzer III effectively swapped roles with the Panzer IV, as from 1942 the last version of the Panzer III mounted the 7.5 cm KwK 37 L/24 that was better suited for infantry support. Production of the Panzer III ceased in 1943. Nevertheless, the Panzer III's capable chassis provided hulls for the Sturmgeschütz III assault gun until the end of the war. Development h ...

Assault Gun
Assault gun (from german: Sturmgeschütz - "storm gun", as in "storming/assaulting") is a type of self-propelled artillery which uses an infantry support gun mounted on a motorized chassis, normally an armored fighting vehicle, which are designed to provide direct fire support for infantry attacks, especially against other infantry or fortified positions. Assault guns were pioneered by the Soviet Union and Nazi Germany during the 1930s, initially being self-propelled guns with direct fire in mind (such as the Soviet SU-5-1), with Germany introducing the first purpose-built (and purpose-named) assault gun, the Sturmgeschütz III, in 1940. Historically, the concept of assault guns was very similar to that of the infantry tank, as both were combat vehicles intended to accompany infantry formations into battle. However, during World War II assault guns were more mobile than tanks and could be utilized as both direct and indirect fire artillery. Although they could approximate the fi ...

Kirov Factory
The Kirov Plant, Kirov Factory or Leningrad Kirov Plant (LKZ) ( rus, Кировский завод, Kirovskiy zavod) is a major Russian mechanical engineering and agricultural machinery manufacturing plant in St. Petersburg, Russia. It was established in 1789, then moved to its present site in 1801 as a foundry for cannonballs. The Kirov Plant is sometimes confused with another Leningrad heavy weapons manufacturer, ''Factory No. 185 (S.M. Kirov)''. Recently the main production of the company is Kirovets heavy tractors. History In 1868 Nikolay Putilov (1820-1880) purchased the bankrupt plant; at the Putilov Works the Putilov Company (a joint-stock holding company from 1873) initially produced rolling stock for railways. The establishment boomed during the Russian industrialization of the 1890s, with the work-force quadrupling in a decade, reaching 12,400 in 1900. The factory traditionally produced goods for the Russian government, with railway products accounting for more than ...

Operation Barbarossa
Operation Barbarossa (german: link=no, Unternehmen Barbarossa; ) was the invasion of the Soviet Union by Nazi Germany and many of its Axis allies, starting on Sunday, 22 June 1941, during the Second World War. The operation, code-named after Frederick Barbarossa ("red beard"), a 12th-century Holy Roman emperor and German king, put into action Nazi Germany's ideological goal of conquering the western Soviet Union to repopulate it with Germans. The German aimed to use some of the conquered people as forced labour for the Axis war effort while acquiring the oil reserves of the Caucasus as well as the agricultural resources of various Soviet territories. Their ultimate goal was to create more (living space) for Germany, and the eventual extermination of the indigenous Slavic peoples by mass deportation to Siberia, Germanisation, enslavement, and genocide. In the two years leading up to the invasion, Nazi Germany and the Soviet Union signed political and economic pacts for st ...
