Military bands in the United Kingdom are the musical units that serve for protocol and ceremonial duties as part of the British Armed Forces. They have been the basis and inspiration for many military bands in the former British Empire and the larger Commonwealth of Nations as well as musical organizations in other countries. Military musical units with British influence include United States military bands, the Japan Ground Self-Defense Force Music Corps and the Military Band of Athens. British military bands are controlled by the military music departments of the three services that compose the armed forces. These include the Royal Marines Band Service, the Corps of Army Music, and the Royal Air Force Music Services. British style brass bands and carnival bands were then and are currently inspired by the British Armed Forces and its brass bands, especially of the Army's regular and reserve formations, as they follow a similar format as it relates to brass and percussion instruments.
