By 2009, the RAFP had served in 66 countries around the globe . </P> <P> RAFP non-commissioned officers and warrant officers are noticeable by their white - topped caps (giving rise to their nickname of "Snowdrops"), which they have worn since 1945, and by black and red flashes worn below their rank slides . RAFP commissioned officers wear the standard peaked cap of all RAF officers, with the red and black flashes . In dress uniform, all RAFP wear a red and black brassard on the left arm, reflecting the flashes worn with normal working dress .
