Chemical warfare (CW) involves using the toxic properties of chemical substances as weapons. This type of warfare is distinct from nuclear warfare, biological warfare and radiological warfare, which together make up CBRN, the military acronym for chemical, biological, radiological, and nuclear, all of which are considered "weapons of mass destruction" (WMDs), a term that contrasts with conventional weapons.
A tankette is a tracked armoured fighting vehicle that resembles a small tank, roughly the size of a car. It is mainly intended for light infantry support and scouting. Colloquially it may also simply mean a small tank.
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 machine gun fire at 600 yards (550 m) range.
The Type 97 Light armored car Te-Ke 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. It was designed as a fast reconnaissance vehicle, and was a replacement for the earlier Type 94 tankette.
The Type 95 Ha-Gō was a light tank used by the Empire of Japan during the Second Sino-Japanese War, at Nomonhan against the Soviet Union, and in the Second World War. It proved sufficient against infantry but, like the American M3 Stuart light tank, was not designed to combat other tanks. Approximately 2,300 were produced, making it the most numerous Japanese armoured fighting vehicle of the Second World War.
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.
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.
The Special Type 3 Launch Ka-Chi was an amphibious medium tank developed by the Imperial Japanese Navy in World War II. The Type 3 Ka-Chi was based on an extensively modified Imperial Japanese Army Type 1 Chi-He medium tank and was a larger and more capable version of the earlier Type 2 Ka-Mi amphibious tank.
The Type 98 So-Da was an armored personnel and ammunition carrier used by the Imperial Japanese Army in World War II.
The Imperial Japanese Army (IJA) initially purchased foreign tanks for evaluation during World War I, and began developing its own indigenous designs during the late 1920s.
The Type 2 Ke-To was a light tank of World War II, produced in small numbers for the Imperial Japanese Army as an improvement of the existing Type 98 Ke-Ni. No Type 2 Ke-To light tanks are known to have engaged in combat prior to Japan's surrender at the end of World War II.
The Type 89 medium tank I-Go was a medium tank used by the Imperial Japanese Army from 1932 to 1942 in combat operations of the Second Sino-Japanese War, at Khalkhin Gol against the Soviet Union, and in the Second World War. The Type 89B model was the world's first mass-produced diesel engine tank. The tank was armed with a short-barrel 57 mm cannon for knocking out pillboxes and masonry fortifications, and proved effective in campaigns in Manchuria and China, as the Chinese National Revolutionary Army had only three tank battalions to oppose them, which consisted primarily of Vickers export models, German Panzer Is, and Italian CV33 tankettes. The Type 89 was a 1920s design medium tank, built to support the infantry, and thus lacked the armor or armament of 1940s generation Allied armor; it was regarded as obsolete by the time of the 1939 battles of Khalkhin Gol, against the Soviet Union. The code designation "I-Go" comes from the katakana letter [イ] for “first” and the kanji [号] for "number". The designation is also transliterated Chi-Ro and sometimes "Yi-Go".
This article deals with the history and development of tanks of the Japanese Army from their first use after World War I, into the interwar period, during World War II, the Cold War and modern era.
Reconnaissance regiment in Japanese language, was the type of the military establishment within Imperial Japanese Army in the 1940-1945 period. Reconnaissance regiment was the type of unit derived from Cavalry regiment, tasked with combat scouting. In Japanese military literature reconnaissance regiment is usually abbreviated by SO letters. These regiments were attached to the large number of the Japanese division at the opening stages of the Pacific War. In modern Japan, these regiments are equivalent to Reconnaissance battalion in the divisions of the Japan Ground Self-Defense Force.
