The Tosan (sometimes known as Towsan,^[1] meaning "wild horse" or "fury"^[2]) is an Iranian light tank. Iran calls it a "Quick Reaction" tank because the tank is said to be capable of rapid response and is built for strategic missions.^{[citation needed]}

Production started in 1997,^[2] but the tank was only produced in small numbers.^[1] Colonel Nasser Arab-Beigi, head of the self-sufficiency unit of the IRGC ground forces, announced the mass-production of the Tosan on June 30, 2008, as part of the country's campaign for defense self-sufficiency.^{[citation needed]}

In July 2020, Tosans were deployed to the northwestern borders of Jolfa and Khodaafarin due to escalating tensions between Armenia and Azerbaijan.^[3]

The Tosan's design is based on the British FV101 Scorpion;^[4] the tank is fitted with a 90 mm gun, Toophan missile launchers (some were mounted),^[5] and improved firing and targeting systems.^{[citation needed]} The tank can drive long distances on its tracks and does not need to be carried on trucks.^[2]

Iranian sources reported that the Tosan's front armor is armored against bullets up to 12.7 caliber.^{[citation needed]} It is equipped with a diesel engine.^{[citation needed]}
