Reconnaissance Regiments (Japan)
The Reconnaissance regiment (Sōsaku-rentai (搜索聯隊) or Sōsaku-tai (搜索隊)) in the Japanese language was a type of military establishment within the Imperial Japanese Army during the 1940-1945 period. Derived from the Cavalry regiment, the ''Reconnaissance regiment'' was tasked with combat scouting. In Japanese military literature, the term ''reconnaissance regiment'' is commonly abbreviated as SO. These regiments were often attached to numerous Japanese divisions during the initial stages of the Pacific War. In contemporary Japan, these regiments are analogous to Reconnaissance battalions within the divisions of the Japan Ground Self-Defense Force. Historical background During the Second Sino-Japanese War, Japanese military commanders frequently faced challenges requiring reconnaissance, rapid message transfer, and the utilization of maneuver warfare advantages. These tasks were typically carried out by cavalry regiments within the Japanese army (see Japanese cavalry r ...

Japanese Language
is the principal language of the Japonic languages, Japonic language family spoken by the Japanese people. It has around 123 million speakers, primarily in Japan, the only country where it is the national language, and within the Japanese diaspora worldwide. The Japonic family also includes the Ryukyuan languages and the variously classified Hachijō language. There have been many Classification of the Japonic languages, attempts to group the Japonic languages with other families such as Ainu languages, Ainu, Austronesian languages, Austronesian, Koreanic languages, Koreanic, and the now discredited Altaic languages, Altaic, but none of these proposals have gained any widespread acceptance. Little is known of the language's prehistory, or when it first appeared in Japan. Chinese documents from the 3rd century AD recorded a few Japanese words, but substantial Old Japanese texts did not appear until the 8th century. From the Heian period (794–1185), extensive waves of Sino-Ja ...

Battles Of Khalkhin Gol
The Battles of Khalkhin Gol (; ) were the decisive engagements of the undeclared Soviet–Japanese border conflicts involving the Soviet Union, Mongolian People's Republic, Mongolia, Empire of Japan, Japan and Manchukuo in 1939. The conflict was named after the river Khalkhyn Gol, Khalkhin Gol, which passes through the battlefield. In Japan, the decisive battle of the conflict is known as the after Nomonhan Burd Obo, an Ovoo, ''obo'', a cairn set as a border marker in the Yongzheng period of the Qing dynasty. The battles resulted in the defeat of the Japanese Sixth Army. Background After the Japanese invasion of Manchuria, Japanese occupation of Manchuria in 1931, Japan turned its military interests to Soviet territories that bordered those areas.

23rd Division (Imperial Japanese Army)
The was an infantry division in the Imperial Japanese Army. Its call-sign was the . The 23rd Division was formed in Kumamoto on 4 April 1938, on the same day as 15th, 17th, 21st and 22nd divisions, as part of the military build-up following the outbreak of the Second Sino-Japanese War. The first divisional commander was Michitarō Komatsubara. Action Battle of Khalkhin Gol Upon formation, the 23rd Division was almost immediately sent to the Northern frontier of Manchukuo, where it replaced a cavalry brigade on garrison duties in Hailar (in what is now part of Inner Mongolia). The 23rd Division was thus the primary Japanese division involved in the Battle of Khalkhin Gol against the Red Army of the Soviet Union, from 11 May to September 1939. The 23rd Division had engaged Soviet forces by progressively increasing detachments, first by its reconnaissance regiment (which was promptly lost and reformed) and then by 64th Infantry Regiment, which was also defeated a ...

Self-propelled Gun
Self-propelled artillery (also called locomotive artillery) is artillery equipped with its own propulsion system to move toward its firing position. Within the terminology are the self-propelled gun, self-propelled howitzer, self-propelled mortar, and self-propelled rocket artillery. They are high-mobility vehicles, usually based on continuous tracks carrying either a large field gun, howitzer, mortar (weapon), mortar, or some form of rocket (weapon), rocket/missile launcher. They are usually used for long-range indirect-fire, indirect bombardment support on the battlefield. In the past, self-propelled artillery has included direct-fire vehicles, such as assault guns and tank destroyers, which were typically well-armoured vehicles often based upon the chassis of a tank. In lieu of the standard tank's general-purpose tank gun, main gun that fired both high-explosive and anti-tank ammunition, direct-fire vehicles had specialized roles, with assault guns providing close fire-supp ...

Type 95 Ha-Go
The was a light tank used by the Empire of Japan during the Second Sino-Japanese War, at the Battles of Khalkhin Gol against the Soviet Union, and in the Second World War. It proved sufficient against infantry but was not effective against other tanks. Approximately 2,300 were produced, making it the most numerous Japanese armoured fighting vehicle of the Second World War. History and development From early 1930s, the Japanese army began experimenting with a mechanized warfare unit combining infantry with tanks. However, the Type 89 Medium tank could not keep pace with the motorized infantry, which could move at by truck. For transport, tanks could be loaded on train platforms like in any other army of the time. To solve this problem, Tomio Hara of the Army Technical Bureau proposed a new light tank capable of 40 km/h speed and started development in 1933. The prototype of the tank was begun in 1933 and completed in June 1934 at the Army's Sagami Arsenal. Initial tests ...

Type 97 Chi-Ha
The was a medium tank used by the Imperial Japanese Army during the Second Sino-Japanese War, the Battles of Khalkhin Gol against the Soviet Union, and the Second World War. It was the most widely produced Japanese medium tank of World War II. The 57 mm main gun, designed for infantry support, was a carry over from the Type 89 I-Go medium tank. The suspension was derived from the Type 95 Ha-Go light tank, but used six road wheels instead of four. The 170 hp Mitsubishi air cooled diesel engine was a capable tank engine in 1938. The Type 97's low silhouette and semicircular radio antenna on the turret distinguished the tank from its contemporaries. After 1941, the tank was less effective than most Allied tank designs. In 1942, a new version of the Chi-Ha was produced with a larger three-man turret, and a high-velocity Type 1 47 mm tank gun. It was designated the Type 97-Kai ("improved") or Type 97 ''Shinhōtō Chi-Ha'' (; "New turret Chi-Ha"). History and developm ...

Type 97 Motorcycle
The Type 97 motorcycle, or Rikuo, was a copy of a Harley-Davidson motorcycle produced with a sidecar from 1935 in Japan under license from Harley-Davidson by the Sankyo Company (later Rikuo Nainen Company). Some 18,000 of the machines were used by the Imperial Japanese forces during World War II. A variation was also manufactured without a side car, called the . In the years after World War I, Harley-Davidson's US sales declined while dozens of US motorcycle brands went under, primarily as a result of the decline in the price of the Ford Model T car, triggering a national shift from motorcycles to cars for cheap transportation. Harley-Davidson sought to make up the lost sales abroad and was selling 2,000 units per year in Japan by the middle of the 1920s. In 1932 Harley-Davidson licensed Sankyo Trading Company to build complete motorcycles in Japan, under the name Rikuo, which meant King of the Road.

Type 95 Reconnaissance Car
The Type 95 was a Japanese scout car built by , and was used during the war with China and World War II in the East. Between 1936 and 1944 approximately 4,700 were built. It was the only completely Japanese designed reconnaissance car ever used by the Imperial Japanese Army, which tended to use civilian cars. Its nickname is the "Yonki" (よんき) which in Japanese means "all-wheel drive". In the field, soldiers often called it the '' "daruma"'' after the Buddhist symbol for good luck. It is one of the world's first four-wheel drive passenger vehicle placed into mass production, prior to the Laffly V15 (1937-1938), the GAZ-61 (1938) and Willys MB "jeep" (1941). The Type 95 accommodated three people - two in the front and one in the back. The two-cylinder, V-twin, four-stroke, air-cooled gasoline engine, which developed at 3,300 rpm, was an advantage in cold climates found in China, and had 4-wheel drive, using a gearshift activated transfer case to engage the front wheels. ...
