Sergeant Major General

Sergeant Major General is a now extinct military rank that can trace its origins to the Middle Ages. Originally simply Sergeant Major, the title signified a general officer, commander of an army's infantry and typically third in command of the army as a whole (after the Lieutenant General and Captain General); he also acted as a sort of chief of staff.
