After posting this yesterday and receiving a few comments I decided to add my own little anecdote. Whilst working on protection duties around St James's Palace, just down the road from Buckingham Palace, I nipped into the guardroom for a brew. The Gurkha Regiment was doing their stint of Palace Guard duties. The duty officer had just been speaking to a young soldier, who seemed a little sad. The officer told me that this young Gurkha had just requested he be allowed to do 24 hours straight guard duty at Buckingham Palace, without relief, just for the honour of it. The officer told me he had to turn the request down, or they'd all want to do it.
