You could also add the Atholl Highlanders. The Atholl Highlanders are a Scottish infantry regiment, based in Blair Atholl; the regiment is not part of the British Army. Instead, the regiment is in the private employ of the Duke of Atholl. Currently, the Atholl Highlanders are a purely ceremonial regiment, of approximately 100 men, including pipes and drums. The regiment is responsible for the defence of Blair Castle, the surrounding estate and its inhabitants, but in practice usually only parades twice a year at the regiment's annual inspection when the present Duke comes from his home in South Africa to inspect his men, and the Atholl Gathering Highland Games, which is hosted by the Duke, on the last weekend in May.
