Lieutenants and above wear white shirts with gold badges and gold 'M.P.D.' insignia pinned on each side of the collar. Their insignia of rank is displayed on the shoulder epaulets of the uniform (as in the military). The badges and cap plates for higher-ranking officers are gold and engraved with the wearer's rank-title. With the exception of their badges and rank insignia the outer uniform dress is the same for all ranks, but may include a blazer with any awarded service ribbons displayed above the badge.
