One of the most anticipated performers over the years at the Royal Edinburgh Military Tattoo has been the Queen's Colour Squadron - an RAF regiment which has become known for its flawlessly polished drill routines.
The squadron, which started life in the early 1920s, and celebrated its 75th birthday this year, officially became the Royal Air Force's Drill Unit in 1960.
In recognition of the regiment's extraordinary parade prowess, the sovereign awarded the regiment with the Queen's Colour, meaning that they have the honour of providing the Escort Squadron whenever the colour is paraded.
Although purely ceremonial for 30 years, reforms within the military led to the squadron being given an operational role as No. 63 Squadron.
The squadron is entirely unique within the RAF, undertaking both ceremonial and field squadron commitments.
It appears in the Guinness Book of Records for completing over 2,700,000 foot and rifle drill movements in 23 hours and 55 minutes.
The British military has a number of units whose primary focus is their ceremonial role.
Perhaps the best known of these is the Household Division, who carry out numerous ceremonial duties, including The Changing of the Guard, Guard at Windsor, and Trooping the Colour.
Although they're not short of pomp and ceremony, there’s no denying that the Queen's Colour Squadron's intricate formations are something special.
Take a look at some of their most impressive moments:
