The Queens Colour Squadron, 63 Squadron Royal Air Force Regiment, is currently based at RAF Uxbridge. The Squadron is unique within the RAF Regiment as it has two roles: That of a regular RAF Regiment Field Squadron and also as the Royal Air Force drill and ceremonial Squadron.

Throughout the year when not on parade the Squadron maintains its operational role as a Field Squadron. Members of the Squadron served as reinforcements to other RAF Regiment Squadrons during the Gulf War conflict. More recently, the Squadron has undertaken operational duties in Cyprus, United Nations duties in the former Republic of Yugoslavia and in Kuwait as part of Op Bolton.

The RAF has had a ceremonial drill unit based at RAF Uxbridge in Middlesex, since the early 1920's and as custodian of the Queen's Colour for the Royal Air Force in the United Kingdom, the Squadron has the honour of providing Escort Squadron wherever the Colour is paraded. The Squadron provides Guards of Honour for members of the Royal Family, visiting Heads of State and civil and military dignitaries. In addition, during its history the Squadron has performed Public Duties at Buckingham Palace, St James' Palace, the Tower of London and Windsor Castle.

The Squadron is perhaps best known for its continuity drill displays. The displays are a series of precision drill movements executed without a single word of command and require the gunners to memorise upwards of 350 separate movements, all of which are taken directly from the RAF drill manual, and are not made up merely to enhance a performance. The Squadron is a World Record holder, having completed 2,001,384 rifle and 721,278 foot movements in 23 hours and 55 minutes at RAF Uxbridge on 8-9 July 1987, and is included in the Guinness Book of Records.
