Aide-de-camp to Monarchs
When one is appointed a personal aide-de-camp to the monarch, it lasts for the appointees lifetime, unless rescinded by the monarch who appointed him or her. Each monarch appoints their own aides-de-camps at their prerogative and can appoint someone who was a personal aide-de-camp to a previous monarch, such as in the case of Louis Mountbatten, Earl Mountbatten of Burma, who was appointed a personal aide-de-camp by King Edward VIII, King George VI, and Queen Elizabeth II. (see: https://www.nationalarchives.gov.uk/pathways/firstworldwar/transcripts/service_records/navalofficer_sr.htm) Thus Mountbatten was entitled to and did wear the royal cypher of all three monarchs on his shoulder straps (see: https://twitter.com/sarahdiaryz/status/1667624953766633472). Conversely, for example, Prince Phillip, Duke of Edinburgh, was only appointed an aide-de-camp by King George VI and not his wife, so he only wore the cypher of King George VI on his shoulder straps and not one of Queen Elizabeth II. As William, Prince of Wales, and Prince Edward, Duke of Edinburgh, have been appointed aides-de-camp by King Charles and were previously ADCs to Queen Elizabeth II, they are entitled to and do wear both the cyphers of both monarchs on their shoulder straps now (read the footnote linked to their entries under King Charles).
