The Flechas (Portuguese for Arrows) were an elite paramilitary tactical unit of the Portuguese secret police (PIDE, latter renamed DGS) that operated in Angola and Mozambique during the Portuguese Colonial War. Unlike most of the other Portuguese special forces that were employed in the several theatres of operations of the conflict, the Flechas were not a de jure military unit but a PIDE/DGS (secret police) unit.
