The Earl of Wessex was given the responsibility of taking the salute on Horse Guards Parade during the Remembrance Sunday commemorations.
Prince Edward took the salute alongside the newly appointed Secretary of State for Defence, Gavin Williamson.
10,000 veterans marched past the Cenotaph and saluted the Earl, who was stood in front of Guards Memorial.
Earlier in the day, Prince Edward laid a wreath at the cenotaph alongside his sister, the Princess Royal, and the Duke of Kent.
The member of the Royal Family who receives the salute usually alternates each year.
Last year, the Prince of Wales took the salute. Other royals to have taken on the responsibility include the Duke of Cambridge, the Duke of Edinburgh and the Duke of York.
Prince Edward joined the Royal Marines upon his graduation, but he dropped out in 1987, only completing a third of the training programme.
Despite this, he is the Honorary Colonel of The Royal Wessex Yeomanry and also holds other honorary military appointments. These include Royal Honorary Colonel of The London Regiment, Honorary Air Commodore of Royal Air Force Waddington, Royal Colonel of 2nd Battalion The Rifles and Commodore in Chief of The Royal Fleet Auxiliary.
The Prince also holds a number of honorary military appointments in Canada.
At the remembrance commemorations on Sunday morning, Prince Charles laid a wreath on behalf of his mother, The Queen, who this year watched the ceremony from the balcony of the Foreign Office alongside her husband, The Duke of Edinburgh.
After the heir-to-the-throne laid a wreath on behalf of Her Majesty, an enquiry placed a wreath at the Cenotaph on behalf of 96-year-old Prince Philip.
The Duchess of Cambridge, the Duchess of Cornwall, the Countess of Wessex and Princess Alexandra joined Her Majesty and Prince Philip as they watched on from the balcony.
