Queen Elizabeth II led Britain's annual Remembrance Day service on Sunday – decades after the British monarch served in the Second World War.
The Queen and other members of the Royal Family laid wreaths at The Cenotaph in Whitehall Sunday morning.
The 87-year-old queen is the last surviving head of state who served in uniform during the Second World War and remains the only female member of the royal family to have entered the armed forces.
Last year, never-before-seen photos of the Queen surfaced, which show her serving with the Women's Auxiliary Territorial Service in March 1945.
At the time, the 18-year-old was training as a driver and a mechanic.
In one of the photos, which have since been donated to the Yorkshire Air Museum, the queen is seen doing maintenance work on an ambulance.
Another photo shows the teenaged future monarch helping to change a car tire.
Her grandsons, Prince William and Prince Harry, have since followed her in her footsteps.

William served in the military for more than seven years, but announced in September that he was wrapping up his tour of duty as a search-and-rescue helicopter pilot with the Royal Air Force to focus on his royal duties and charity work.
Prince Harry, known as Capt. Wales in the army, has undertaken two tours in Afghanistan. Earlier this year, the 29-year-old completed a 20-week deployment in Afghanistan as a co-pilot gunner on an Apache and has since flown missions in the U.K.
