Prince Harry will step down from his military appointments, it was been decided last month.
Buckingham Palace said the Duke and Duchess of Sussex "understand that they are required to step back from royal duties, including official military appointments".
Following discussions with the Queen and the Royal Family, after which it was announced the couple will stop using their HRH titles, "as they are no longer working members of the Royal Family".
The changes will come into effect from the Spring.
The Duke will, however, continue his role as patron of the Invictus Games Foundation.
Harry and Meghan first announced their intention to "step back as 'senior members' of the Royal Family" in January.
The Duke of Sussex was appointed Captain General Royal Marines in December 2017, succeeding his grandfather, the Duke of Edinburgh, in the role.
In June 2018, Prince Harry received promotions in all three services, becoming Lieutenant Commander in the Royal Navy, Major in the British Army, and Squadron Leader in the Royal Air Force - ranks it was announced in February he will retain.
Prince Harry will step back from the following military appointments:
- Captain General Royal Marines
- Honorary Air Commandant, RAF Honington
- Commodore-in-Chief, Small Ships and Diving, Royal Naval Command
Prince Harry is also the founder of the Invictus Games - the competition for injured, sick and wounded Armed Forces personnel and veterans which he established in 2014.
It was also the setting for the Duke and Duchess' first public appearance together as a couple when they attended the 2017 competition in Toronto.
He was also in the Army for ten years, during which time he undertook two operational tours of duty in Afghanistan, and qualified as an Apache Aircraft Commander.
Prince Harry's military career
Passing his Regular Commissions Board (RCB), the qualification necessary to train at Sandhurst, in September 2004, Prince Harry entered RMAS in May 2005 to begin 44 weeks of Officer Cadet training.
In January 2006, Clarence House announced he was to join the Blues and Royals, after which he was commissioned as an Army officer on 12 April that year.
In 2007, the prince was deployed to Afghanistan for ten weeks, working as a forward air controller, coordinating air strikes on Taliban positions.
However, his tour ended early following reports in international media of his whereabouts.
On 25 February 2008, it was made known Prince Harry had been serving with the Army in Helmand Province, Afghanistan for more than two months.
He was promoted to the rank of Lieutenant with The Household Cavalry on 13 April 2008.
The Duke of Sussex then retrained as an Apache pilot in the Army Air Corps and returned to Afghanistan in 2012 as a helicopter co-pilot and gunner.
His decision to leave the Army was confirmed in March 2015.
Prince Harry ended his military career in June 2015, following a secondment to the Australian military.
General Sir Nicholas Carter, the then-Chief of the General Staff said that Prince Harry had "achieved much in his ten years as a soldier.
"He has been at the forefront throughout his service," he said.
Recent engagement with the British armed forces has included a Christmas message for young children who have lost a parent in the UK Armed Forces.
