The Pathfinders were elite squadrons in RAF Bomber Command, during World War II. They located and marked targets with flares, which a main bomber force could aim at, increasing the accuracy of their bombing. While the majority of Pathfinder squadrons and personnel were from the Royal Air Force, the group also included many from the air forces of other Commonwealth countries. The Pathfinder Force (PFF) was formed into a group No. 8 (Pathfinder Force) Group in January 1943.
