In addition to honours and awards the RAF recognises particular achievements with the award of a commendation. Typically these are made by the Air Officer in Command of the particular theatre.
Not long out of training, and posted to Hong Kong, Roy received the AOC-in-C Hong Kong's Commendation for meritorious service. I wonder what he had done there to achieve such recognition so early in his service.
He received further commendations in 1978 (Air Officer Commanding in Chief's Commendation)
and in 1988 (Air Officer Commanding-in-Chief, RAF Support Command Commendation). Here is a letter from the Station Commander of RAF Digby informing him of the award (complete with incorrect initials!)
