The Tanque Argentino Mediano (TAM; English: Argentine Medium Tank) is the main battle tank in service with the Argentine Army. Lacking the experience and resources to design a tank, the Argentine Ministry of Defense contracted German company Thyssen-Henschel. The vehicle was developed by a German and Argentine team of engineers, and was based on the German Marder infantry fighting vehicle.

The TAM met the Argentine Army's requirement for a modern, lightweight and fast tank with a low silhouette and sufficient firepower to defeat contemporary armored threats. Development began in 1974 and resulted in the construction of three prototypes by early 1977 and full-scale production by 1979. Assembly took place at the local 9,600-square-meter (103,000 sq ft) TAMSE plant, founded for the purpose by the Argentine government. Economic difficulties halted production in 1983, but manufacturing began anew in 1994 until the army's order of 200 tanks was fulfilled.

The TAM series includes seven different variants, such as a 155 mm (6.1-inch) self-propelled howitzer and a self-propelled mortar vehicle. In total, over 280 such vehicles were built, including armored personnel carriers, artillery and mortar pieces. The TAM and VCTP (Infantry Fighting Vehicles based on the TAM chassis) were manufactured for the Peruvian Army, only to be integrated into the Argentine Army when Peru canceled the contract. The TAM also competed for other export orders, but the TAM was ultimately not exported.

The TAM has never seen combat, although 17 VCTP were deployed to Croatia for the United Nations UNPROFOR peacekeeping mission.

During the 1960s Argentina sought to replace its aging fleet of tanks, which included British Sherman V Firefly tanks and American M3A1 half-tracks dating from shortly after the Second World War. In their attempts to procure equipment from the United States, Argentina could only secure 50 M41 Walker Bulldogs (undelivered) and 250 M113 armored personnel carriers. When the United States turned down requests for further equipment, the Argentine government turned to the other side of the Atlantic, putting their "Plan Europa" (Plan Europe) into action. It was hoped that European technology could stimulate Argentine industry so the country could produce its own armaments in the future. Argentina procured 80 AMX-13 light tanks, as well as 180 AMX-VCIs and 24 AMX-155 F3s, from the French government, manufacturing around 40 AMX-13s and 60 AMX-VCIs at home. The French AMX-30 and German Leopard 1 were also examined as possible replacements for the Argentine Sherman fleet.
