Equipped with the SAR-21 Assault Rifle with bayonets attached, the guards wear the Ceremonial Uniform (known as the No. 1), which (except in the case of Navy honour guards) have various colours imbued on a thin strip running down the outer-sides of the trousers indicating the unit's service of origin (red for the Army, light-blue for the Air Force, and black for the Police). They also wear distinctive badges, medals, award ribbons, and buttons. These Guard of Honour units will typically be contrasted by at least one contingents of other servicemen attired in their regular uniform (the No. 4 uniform for the SAF units and the No. 3 uniform for the SPF unit).
