WThe BT tanks 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.
WThe Begleitpanzer AIFSV was a project of the companies Thyssen-Henschel and Bofors. Only a single prototype was built. In the mid-1970s, the two then-existing companies Thyssen-Henschel and Bofors began without government a mandate with the development of an infantry escort tank, as they believed to have discovered a gap in a light fire support platform. The vehicle was first introduced in November 1977. However, due to lack of interest from potential buyers, the project was not pursued.
WThe BT-SV was an experimental Soviet light tank. In 1936, Soviet engineer Tsiganov proposed a new high-speed (BT) light tank based on the BT-7. The design was to incorporate sloped armor similar to the T-34, which was also being developed at the time, and a transmission identical to that of the BT-7. The armor was angled at around 15°-58°. It could protect the tank from 45mm rounds. Only two prototypes were built, both of which saw field testing. The vehicle never saw mass production, and resources were instead focused on the production of the T-34 medium tank. All work on this project was abandoned when designer Tsiganov was arrested during purges in 1938.
WThe Special number 3 light tank Ku-Ro was an experimental Japanese winged light tank project, developed during World War II.
WThe T-34 medium tank is one of the most-produced and longest-lived tanks of all time.
WThe T-46 was a Soviet fast light tank developed in 1935, as an improvement to the earlier T-26. The design was later discarded by the government, after the prototypes were built and tested. The project ended up being too expensive and a poor design. The thin armor, bulky hull and small main gun put the crew in great danger, which made the tank unsuitable for use in combat.
WTank Ex, or MBT Ex, was the code name of the main battle tank developed by the Indian Defence Research and Development Organisation (DRDO) in 2002. It was rumoured the tank would be called Karna, after one of the heroes of the Indian epic The Mahabharata. Tank Ex was developed as a second attempt after the development of the Ajeya by DRDO in order to capitalize on the technology developed for that project. It underwent six months of trials, but was subsequently rejected by the Indian Army. Total eight Tank Ex prototypes were built.
WThe T-34 medium tank is one of the most-produced and longest-lived tanks of all time.
WThe Experimental Medium Tank Chi-Ni was a prototype Japanese medium tank. Initially proposed as a low-cost alternative to the Type 97 Chi-Ha medium tank, it was eventually passed over by its competitor.
WThe experimental Type 98 Chi-Ho was a prototype Japanese medium tank. It was developed on orders from the Imperial Japanese Army. "Chi Ho" indicates that it is designated as the 5th medium (Chi) tank. A total of four prototypes were completed. Two were built in 1940 and two were built in 1941. It did not enter production.
