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. It was produced in greater numbers than any other tank of the period, with more than 11,000 units manufactured giving it the title of the most produced tank during the interwar period. 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-35B was a Soviet multi-turreted heavy tank of the interwar period and early Second World War that saw limited and service with the Red Army. Often called a land battleship, it was the only five-turreted heavy tank in the world to reach production, but proved to be slow and mechanically unreliable. Most of the T-35B tanks still operational at the time of Operation Barbarossa were lost due to mechanical failure rather than enemy action. It was designed to complement the contemporary T-28 medium tank; however, very few were built.
The TK (TK-3) and TKS were Polish tankettes developed during the 1930s and used in the Second World War.
The Type 94 tankette was a tankette used by the Imperial Japanese Army in the Second Sino-Japanese War, at Nomonhan against the Soviet Union, and in World War II. Although tankettes were often used as ammunition tractors, and general infantry support, they were designed for reconnaissance, and not for direct combat. The lightweight Type 94 proved effective in China as the Chinese National Revolutionary Army had only three tank battalions to oppose them, and those tank battalions were equipped only with some British export models and Italian CV-33 tankettes. As with nearly all tankettes built in the 1920s and 1930s, they had thin armor that could be penetrated by .50 caliber (12.7 mm) machine gun fire at 600 yards (550 m) range.
The T-27 was a tankette produced in the 1930s by the Soviet Union. It was based on the design of the Carden Loyd tankette, bought under license from the United Kingdom in 1930.
The Carden Loyd tankettes were a series of British tankettes of the period between the World Wars, the most successful of which was the Mark VI, the only version built in significant numbers. It became a classic tankette design worldwide, was licence-built by several countries and became the basis of several designs produced in various countries.
Tanks were initially deployed in World War I, engineered to overcome the deadlock of trench warfare. Between the two world wars, tanks were further developed. Although they had demonstrated their battlefield effectiveness, only a few nations had the industrial resources to design and build them. During and after World War I, Britain and France pioneered tank technology, with their models generally serving as a blueprint for other countries. However, this initial advantage would slowly diminish during the 1930s, shifting in favor of the Soviet Union and, to a lesser degree, Nazi Germany.
The T-50 was a light infantry tank built by the Soviet Union at the beginning of World War II. The design for this vehicle had some advanced features, but was complicated and expensive, and only a short production run of 69 tanks was completed.
The Type 92 heavy armoured car, also known as the Type 92 cavalry tank, was the Empire of Japan's first indigenous tankette. Designed for use by the cavalry of the Imperial Japanese Army by Ishikawajima Motorcar Manufacturing Company, the Type 92 was designed for scouting and infantry support. The Type 92 was thin armored and lightly armed. Although actually a light tank, it was called sōkōsha in Japanese due to political sectionalism within the Japanese Army. Exactly the same device was used in America with the M1 Combat Car.
OKMO was the tank design team in the Soviet Union during the early 1930s. Located in Leningrad, it produced the design of the T-26 infantry tank, of which about 12,000 would be produced. Most other designs from the bureau never saw the light of day, but it was here that Mikhail Koshkin, designer of the famous T-34 medium tank gained his early experience. The bureau was gutted in the Great Purge and broken up by the beginning of the Second World War.
Sir John Valentine Carden, 6th Baronet MBE was an English tank and vehicle designer. He was the sixth baronet of Templemore, County Tipperary, from 1931.
More than 50 different modifications and experimental vehicles based on the T-26 light infantry tank chassis were developed in the USSR in the 1930s, with 23 modifications going into series production. The majority were armoured combat vehicles: flame tanks, artillery tractors, radio-controlled tanks (teletanks), military engineering vehicles, self-propelled guns and armoured personnel carriers. They were developed at the Leningrad Factory of Experimental Mechanical Engineering by talented Soviet engineers P.N. Syachentov, S.A. Ginzburg, L.S. Troyanov, N.V. Tseits, B.A. Andryhevich, M.P. Zigel and others. Many Soviet tank engineers were declared "enemies of the nation" and repressed during Stalin's Great Purge from the middle of the 1930s. As a result, work on self-propelled guns and armoured carriers ceased in the USSR during that time. T-26 light tanks were also modified into armoured combat vehicles in the field during wartime.

This article on military tanks deals with the history of tanks employed by various military forces belonging to the Kuomintang and Chinese Communist Party (CCP) within China. From the early half of the 20th century, tanks were initially obtained from other countries; eventually indigenously designed Chinese tanks started manufacture and became used during the Cold War and towards the modern era.
This article deals with the history of tanks employed by military forces in Czechoslovakia from the interwar period, and the more conventional tanks designed for the Czechoslovak Army before World War II, and the tanks that ended up as Panzers of the German Wehrmacht during World War II, or in the use of other countries who purchased them before the war began.
The Vickers-Carden-Loyd light amphibious tank, was a series of British experimental pre-World War II light tanks, which, although not taken into British service, were sold to a number of other countries which produced modified versions which were then taken into service.
PZInż 130 was a prototype of Polish amphibious tank of the 1930s. Only a single prototype was built.
