who wears a white cap in the raf
Royal Air Force Police 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. In tactical dress, RAFP personnel wear red "MP" badges, the internationally recognised symbol for military police.
