peaked cap when on duty. Members of the Hong Kong Sea Cadet Corps, Hong Kong Adventure Corps and Hong Kong Air Cadet Corps (including the Ceremonial Squadron) use the British-based cap. The dress uniforms for the Public Security Police Force of Macau and the Corpo de Bombeiros de Macau utilises a peaked cap. However, most police officers in Macau wear berets or ball caps for patrol. United Kingdom Peaked caps are used by a number of civilian services in the United Kingdom. His Majesty's Prison Service and British ambulance services do not currently issue peaked caps to be worn on duty, although they formerly did so. However, peaked caps are still worn with formal uniform on ceremonial occasions. Police Basic headgear for male police officers in the UK is a peaked cap. This includes a cap badge and generally has a black and white diced band (called Sillitoe tartan) around the hat. Caps worn by traffic police officers have white crowns or covers. Caps are also part of the uniforms of male police community support officers (PCSOs), who wear a plain light blue band. Ministry of Defence Guard Service The Ministry of Defence Guard Service currently issues a peaked cap that is a dark shade of navy blue with a leather chin strap and MGS cap badge on the front to all of its male officers. Female officers are issued with a peaked cap of a different shape similar to that of female soldiers. Dog section officers traditionally wear a beret. The cap badge consists of the Ministry of Defence emblem in the centre backed by silver with a navy blue border encircling the emblem that contains text that reads 'Ministry of Defence Guard Service', all below a crown. Fire services Members of British fire services wear standard peaked caps. Female members wear identical caps to male members. Before the Second World War, some British fire brigades, including the London Fire Brigade, wore the peakless Brodrick cap, which had formerly been worn by the British Army. However, when all fire brigades were amalgamated into the National Fire Service in 1941 it adopted the peaked cap, and this was retained when it was disbanded in 1948 and separate fire brigades were again formed by each local authority.
