Hi Guernsey Girl... I immediately regretted not mentioning SAR... as well as the Royal Navy personnel at sea providing our deterrent and power projection, the Army lads and lasses around the world... the list goes on. Over 30,000 personnel deployed, one way or another, away from home across the three Services.
Puts orderly officer into its place, don't you think?
Anyhoo, Merry Christmas one and all, and a very Happy New Year!
