It has a cap band which may be coloured (red for all Royal Regiments and Corps), a crown (formerly khaki, now dark blue, except for Military Police which has always been red, and the Rifles who wear Rifle Green) which may have coloured piping or a regimental/corps colour and a patent leather peak and chinstrap. The chinstrap is usually secured above and across the peak and secured at each end by a small (20 line) button of the appropriate regimental or corps pattern.
