BT-7M
The BT-7 BT (russian: БТ) is the Russian abbreviation for "fast tank" (, ). was the last of the BT series of Soviet cavalry tanks that were produced in large numbers between 1935 and 1940. It was lightly armoured, but reasonably well-armed for the time, and had much better mobility than other contemporary tank designs. The BT tanks were known by the nickname ''Betka'' from the acronym, or its diminutive, ''Betushka.'' The BT-7's successor was the famous T-34 medium tank, introduced in 1940, which replaced all of the Soviet fast tanks, infantry tanks, and medium tanks then in service. Development The first prototypes of the BT-7 had a distinctive canted-ellipse shaped turret mounting both the main gun and a coaxial machine-gun. The specification also called for the project to allow for the installation of new guns without any significant change to the framework: the 76 mm KT-26 or PS-3 main gun (a short-barreled howitzer) and the 45 mm 20K model 1932/38, a lo ...

BT Tank
The BT tanks (russian: Быстроходный танк/БТ, translit=Bystrokhodnyy tank, lit. "fast moving tank" or "high-speed tank") were a series of Soviet light tanks produced in large numbers between 1932 and 1941. They were lightly armoured, but reasonably well-armed for their time, and had the best mobility of all contemporary tanks. The BT tanks were known by the nickname ''Betka'' from the acronym, or its diminutive ''Betushka''. The successor of the BT tanks was the famous T-34 medium tank, introduced in 1940, which would replace all of the Soviet fast tanks, infantry tanks, and medium tanks in service. Design The BT tanks were "convertible tanks". This was a feature that was designed by J. Walter Christie to reduce wear of the unreliable tank tracks of the 1930s. In about thirty minutes, the crew could remove the tracks and engage a chain drive to the rearmost road wheel on each side, allowing the tank to travel at very high speeds on roads. In wheeled mode, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diesel Model V-2
The Kharkiv model V-2 (russian: В-2) was a Soviet diesel tank V-12 engine, the V angle at 60°, with dual overhead camshafts per bank,four valves per cylinder opened by bucket style followers and direct fuel injection, features found on modern high performance diesel engines. Designed at the Kharkiv Locomotive Factory by Konstantin Chelpan and his team. It is found in the BT-7M (BT-8), T-34, KV, IS and IS-10 (T-10) tanks, and by extension, the vehicles based on them, such as the SU-85 and SU-100 tank destroyers based on the T-34 and the ISU-122 and ISU-152 self-propelled guns based on the IS-2. Throughout its production life, output ranged from roughly 450-700 hp. The engine was made of aluminium. The engine cooling system was liquid, of a closed type. It included a water jacket of the cylinder blocks; water radiators; a water pump; a centrifugal fan; a t-valve with steam and air valves, and piping. The cooling system capacity was 90- 95 liters. The radiators were conne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light Tank
A light tank is a tank variant initially designed for rapid movements in and out of combat, to outmaneuver heavier tanks. It is smaller in size with thinner armor and a less powerful main gun, tailored for better tactical mobility and ease of transport and logistics. They are primarily employed in the screening, armored reconnaissance, skirmishing, artillery observation, and supplementing landing operations in a fire support role of expeditionary forces where larger, heavier tanks are unavailable or have difficulties operating safely or efficiently. The fast light tank was a major feature of the pre-World War II army buildup, where it was expected they would be used to exploit breakthroughs in enemy lines created by slower, heavier tanks, with the goal of disrupting communications and supply lines. Numerous small tank designs and "tankettes" were developed during this period and known under a variety of names, including the " combat car". Early light tank designs were gene ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
T-26 Tank
The T-26 tank was a Soviet light tank used during many conflicts of the Interwar period and in World War II. It was a development of the British Vickers 6-Ton tank and was one of the most successful tank designs of the 1930s until its light armour became vulnerable to newer anti-tank guns.Franco, ''El Tanque de la Guerra Civil Española'', p. 74. It was produced in greater numbers than any other tank of the period, with more than 11,000 units manufactured. During the 1930s, the USSR developed 53 variants of the T-26, including flame-throwing tanks, combat engineer vehicles, remotely controlled tanks, self-propelled guns, artillery tractors, and armoured carriers. Twenty-three of these were series-produced, others were experimental models. The T-26 and BT were the main tanks of the Red Army's armoured forces during the interwar period. The T-26 was the most important tank of the Spanish Civil War and played a significant role during the Battle of Lake Khasan in 1938, as well ...

Manchurian Strategic Offensive Operation
The Soviet invasion of Manchuria, formally known as the Manchurian strategic offensive operation (russian: Манчжурская стратегическая наступательная операция, Manchzhurskaya Strategicheskaya Nastupatelnaya Operatsiya) or simply the Manchurian operation (), began on 9 August 1945 with the Soviet invasion of the Japanese puppet state of Manchukuo. It was the largest campaign of the 1945 Soviet–Japanese War, which resumed hostilities between the Union of Soviet Socialist Republics and the Empire of Japan after almost six years of peace. Since 1983, the operation has sometimes been called Operation August Storm after U.S. Army historian David Glantz used this title for a paper on the subject. Soviet gains on the continent were Manchukuo, Mengjiang (the northeast section of present-day Inner Mongolia) and northern Korea. The Soviet entry into the war and the defeat of the Kwantung Army was a significant factor in the Japanese governme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battles Of Khalkhin Gol
The Battles of Khalkhin Gol (russian: Бои на Халхин-Голе; mn, Халхын голын байлдаан) were the decisive engagements of the undeclared Soviet–Japanese border conflicts involving the Soviet Union, Mongolia, Japan and Manchukuo in 1939. The conflict was named after the river Khalkhin Gol, which passes through the battlefield. In Japan, the decisive battle of the conflict is known as the after Nomonhan, a nearby village on the border between Mongolia and Manchuria. The battles resulted in the defeat of the Japanese Sixth Army. Background After the Japanese occupation of Manchuria in 1931, Japan turned its military interests to Soviet territories that bordered those areas. The first major Soviet-Japanese border incident, the Battle of Lake Khasan, occurred in 1938 in Primorye. Clashes between Japanese and Soviet forces occurred frequently along the border of Manchuria. In 1939, Manchuria was a puppet state of Japan known as Manchukuo, and Mongo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Front (World War II)
The Eastern Front of World War II was a Theater (warfare), theatre of conflict between the European Axis powers against the Soviet Union (USSR), Polish Armed Forces in the East, Poland and other Allies of World War II, Allies, which encompassed Central Europe, Eastern Europe, Northern Europe, Northeast Europe (Baltic states, Baltics), and Southeast Europe (Balkans) from 22 June 1941 to 9 May 1945. It was known as the Great Patriotic War (term), Great Patriotic War in the Soviet Union – and still is in some of its successor states, while almost everywhere else it has been called the ''Eastern Front''. In present-day German and Ukrainian historiography the name German-Soviet War is typically used. The battles on the Eastern Front of the Second World War constituted the largest military confrontation in history. They were characterised by unprecedented ferocity and brutality, wholesale destruction, mass deportations, and immense loss of life due to combat, starvation, expos ...

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 ...

BT-42
The BT-42 was a Finnish assault gun, constructed during the Continuation War. It was constructed from captured Soviet BT-7 light tanks and British 4.5-inch howitzers (114 mm-calibre light howitzer, model 1908) from 1918, which had been donated during the Winter War. Only eighteen vehicles were constructed. Development and use As the Second World War progressed, the Soviets were fielding better and better tanks. The Finnish Army, on the other hand, had to make do with a large number of captured tanks, which were for the most part lightly armored and armed. The Finns decided to redesign the BT-7 Model 1937 tank. They constructed a new turret fitted with 76 K/02 gun sights and armed it with British-made 114.3 mm howitzers that had been supplied by the British during the Winter War (Q.F. 4,5 inch howitzer Mark II, also known as ''114 Psv.H/18'' in Finland). Eighteen BT-42 were built and these were pressed into service in 1943. These converted vehicles quickly became ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flamethrower
A flamethrower is a ranged incendiary device designed to project a controllable jet of fire. First deployed by the Byzantine Empire in the 7th century AD, flamethrowers saw use in modern times during World War I, and more widely in World War II as a tactical siege weapon against fortifications. Most military flamethrowers use liquid fuel, typically either gasoline or diesel, but commercial flamethrowers are generally blowtorches using gaseous fuels such as propane; gases are safer in peacetime applications, because their flames have less mass flow rate and dissipate faster, and often are easier to extinguish when necessary. The military use of flamethrowers is restricted through the Protocol on Incendiary Weapons. Apart from the military applications, flamethrowers have peacetime applications where there is a need for controlled burning, such as in sugarcane harvesting and other land-management tasks. Various forms are designed for an operator to carry, while others a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
