Prince Harry received a humanitarian prize for his charitable work with disabled service personnel in Washington.
The 27-year-old prince also met a team of injured British military men and women who took part in a paralympic-style event called the Warrior Games.
Harry was honoured for championing charities such as Walking With The Wounded, ABF The Soldiers' Charity and Help For Heroes, the Daily Express reported.
In accepting the Atlantic Council award he was following in the footsteps of U2 singer Bono, who received the honour in 2010.
Harry was due to be presented with the award by General Colin Powell and was expected to point out that his brother William was equally committed to supporting Britain's Armed Forces.
He has shown dedication to the cause by taking part in a gruelling Arctic challenge with injured Afghanistan veterans.
He has also served on the frontline in Afghanistan and is understood to want to return after completing his training as an Apache helicopter pilot.
"With his brother, Harry has supported military charities for a number of years and wants to use his position to help highlight this," a source said.
The Prince was due to share a stage with UN secretary general Ban Ki-moon, who was also to be honoured. (ANI)
