Only the rank insignia worn by RCAF SP are illustrated here. The senior RCAF Provost Marshal was a Group Captain. Rank insignia was worn on the cuffs of the service dress jacket, and on epaulettes on greatcoats, battledress and shirts.

For several years after the end of the Second World War, the patterns of Warrant and NCO rank insignia remained unchanged. Beginning around 1948, new patterns were introduced, the new and old patterns were worn concurrently until the insignia was standardised in the mid 1950's. These patterns then remained unchanged until Unification.
NCO's rank insignia were worn on the upper sleeve on all orders of dress, Warrant Officer's insignia were worn on the cuff.
