Men and women from across the Army, Navy and Royal Air Force serving at Lashkar Gah in Helmand province, where the headquarters of Task Force Helmand are based, fell silent to mark Remembrance Sunday at 11am.
Meanwhile in London, thousands of veterans and civilians marched past the Cenotaph on Whitehall where the official wreath-laying ceremony was led by Her Majesty The Queen and members of the Royal Family along with members of the Government including Prime Minister David Cameron.
Other Remembrance Sunday ceremonies took place up and down the country and around the world.
Those in Afghanistan included one at Kandahar Airfield where hundreds of UK troops fell silent for two minutes at the Allied War Memorial at the airfield along with a large contingent of coalition troops, including Americans and Canadians.
The commemorations were held in tradition by holding a formal Remembrance Ceremony, attended by UK serving personnel based at KAF as well as ISAF and NATO representatives. The ceremony concluded with the last post, and the laying of the wreath by Commanding Officer 904 EAW. Personnel from the Royal Air Force, the Royal Navy and the Army were all present at the ceremony to pay their respects.
Commanding Officer 904 EAW, Group Captain Richard Barrow said: "It is an honour and a privilege to hold this service and lay a wreath in memory of all those who have lost there lives in the Service of their country. To do so here in Afghanistan is all the more poignant."
