The princes hope to raise support for UK troops
Princes William and Harry have met patients at a medical rehabilitation centre for the armed forces.
They went on a private tour of the facilities at the Defence Medical Services Rehabilitation Centre, Headley Court, near Epsom, Surrey.
The princes met patients undergoing treatment and those with limited mobility, and spoke about next month's City Salute Appeal.
The event, and the clinic visit, are aimed at raising support for UK troops.
Next month's City Salute event will be an open-air event held in the City of London on 7 May.
Members of the public will be asked to help raise money for injured servicemen and women, and the funds raised will go to the City Salute Appeal.
During the tour, Harry was reunited with one of the injured servicemen who shared his return flight from his tour of duty in Afghanistan.
Marine Ben McBean, 21, lost an arm and a leg when a mine exploded during a patrol in the country, and he was flown back to the UK for medical treatment at the same time as the prince left the country.
Both princes also met L/Sgt Adam Ball, 23, of 1st Battalion Grenadier Guards who has spent six months at Hedley Court after he lost a leg when he stepped on an explosive device in Afghanistan.
L/Sgt Ball said the visit had boosted morale at the centre.
"With Harry having done it himself he knows the ins and outs and it's more like banter, talking to an officer maybe, than talking to a royal."
The clinic visited by the princes offers a wide range of therapies to aid rehabilitation.

The site provides consultants, physiotherapists, occupational therapists, speech and language therapists, social workers, a psychologist and a cognitive therapist.
As part of their visit, the princes joined a group of patients and staff to discuss the City Salute event.
The Defence Medical Services Rehabilitation Centre is set to benefit from the drive, with projects to be funded including a swimming pool and sports complex for physiotherapy and family accommodation.
In an earlier tour of the centre, the princes visited the hydro-therapy pool, the physiotherapy room, the workshops where prosthesis are made, the gymnasium and the wards.
The clinic was originally developed as a centre for aircrews and officers after a collection of funds and donations during the war.
And, in 1984, it extended its remit to treating personnel of all ranks and Services.
Since 2002, the site has delivered rehabilitation as part of a network of 14 medical Regional Rehabilitation Units.
