General San Martín Regiment of Mounted Grenadiers (Regimiento de Granaderos a Caballo General San Martín) is the name of two Argentine Army regiments: * The Mounted Grenadiers 1812–1826: A historic regiment first commanded by Argentine national hero José de San Martín in 1812. The regiment fought in the Argentine War of Independence and the Cisplatine War. The regiment became the Presidential escort unit in 1825. Disdaining to renew its numbers with soldiers who had not fought in the independence war, the Regiment disbanded in 1826. * The Mounted Grenadiers 1903–today: A modern regiment in the Argentine Army which acts as the presidential guard of honour and national ceremonial unit. This regiment claims the heritage of the original regiment of 1812 but has no direct link or lineag
