Soldiers from F Company The Scots Guards have been preparing to provide the Queen's Guard when she visits Scotland.
They will take on the ceremonial role as part of the Household Division.
The role requires perfection, with troops being put through their paces on and off the parade ground.
"All guards have to perform ceremonial duties at some point in their career," said Major Tom Mortensen.
Uniforms are a big part of ceremonial duties and in the barracks, soldiers have also been making sure they look the part.
"I always start off with my belt," explained Guardsman Conor Hughes.
Once the belt is polished, the soldier then moves on to the boots.
F Company is primarily based in London, however, the majority of the soldiers do hail from north of the border meaning a trip back up to Edinburgh is often a welcome trip.
"Scots Guards has to be the highest standard," said Lance Corporal Lance Adams, who grew up near Edinburgh.
"Being at Edinburgh Castle and Holyrood Palace makes you feel just a little bit prouder."
The Scots Guards have been providing the guard for the monarch since 1642.
