Coldstream Guards march through London
The 1st Battalion Coldstream Guards have gone on parade through central London in honour of those who died and those still fighting.
Led by the Regimental Band of the Coldstream Guards, the 650 soldiers marched from Wellington Barracks to the Guards Memorial at Horse Guards Parade.
Many of the soldiers have recently returned from Afghanistan.
The parade followed a service of remembrance at the Guards Chapel.
The battle group included men and women from several different corps and regiments with medics, engineers, artillery men, chefs and mechanics marching alongside guardsmen.
Commanding Officer Lt Col Toby Gray said thanks to the efforts of the soldiers a major road had been built, a school opened and clinics are under construction.
"The challenges were huge, but working closely alongside our Afghan national army and police counterparts and with the local government, we have made a real difference," he said.
"Sadly, the gains we made were not without cost; seven members of the Battle Group gave their lives and many others were injured.
"Some of those are on parade today and together we will honour our dead and keep in mind those who replaced us and are continuing the fight even as we march."
Ahead of the march, the ceremonial company of the Coldstream Guards - No 7 Company - joined the Queen's Guard.
One of the Coldstream Guards soldiers who died was L/Cpl Darren Hicks who was killed in an explosion in Afghanistan in February.
His three-year-old son Henry attended the memorial service at the Guards' Chapel.
Troops had been dressed in desert combats alongside their ceremonial colleagues wearing the traditional ceremonial dress with bearskins and tunics.
