Grey's Scouts were a Rhodesian mounted infantry unit raised in July 1975 and named after George Grey, a British soldier and governor. Based in Salisbury it patrolled Rhodesia's borders during the Rhodesian Bush War, and then became a regiment of the Special Forces of Zimbabwe in June 1980. It was totally disbanded in July 1986 because of a lack of resources.

Mounted infantry were infantry who rode horses instead of marching. The original dragoons were essentially mounted infantry. According to the 1911 Encyclopædia Britannica, "Mounted rifles are half cavalry, mounted infantry merely specially mobile infantry." Today, with motor vehicles having replaced horses for military transport, the motorized infantry are in some respects successors to mounted infantry.
