The Regiment of Mounted Grenadiers is the name of two Argentine Army regiments of two different time periods: a historic regiment that operated from 1812 to 1826, and a modern cavalry unit that was organized in 1903.
The first Regiment of Mounted Grenadiers, formed in 1812, fought in the Argentine War of Independence under José de San Martín, and the Cisplatine War, subsequently becoming the Presidential bodyguard in 1825. Refusing to replenish its membership with soldiers who had not fought in the Argentine War of Independence, the regiment disbanded in 1826.
The second Regiment of Mounted Grenadiers was formed in 1903, and serves as the national ceremonial unit. It claims the original regiment of 1812 as its heritage, but has no direct link or lineage.
