The late Queen enlisted in the Auxiliary Territorial Service as a teenager towards the end of World War II.

The Royal Family will also take part in a Remembrance Sunday service at the Cenotaph when a two-minute silence will be held at 11:00 GMT.
Prime Minister Rishi Sunak and Labour leader Sir Keir Starmer represented the two main political parties at the landmark London venue.

The Chelsea Pensioners, among the oldest retired members of the Army, received applause as they took their seats.
The Royals joined the crowd to sing Jerusalem after the remembrance book, which contains the names of British war dead was brought into the venue. One of those who brought it into the hall was Captain Dmytro Donskoi, defence and air attache for Ukraine.
It ended with a rendition of God Save The King and three cheers, after which Charles waved to the crowd who applauded as the Royal Family left.
