The Queen and Duke of Edinburgh will visit the armed forces' dedicated rehabilitation centre in Surrey for seriously injured servicemen and women.
The royal couple will tour Headley Court where wounded service personnel are given treatment and support to rebuild their military careers.
The Defence Medical Rehabilitation Centre near Leatherhead is where most combat casualties receive the final stage of their rehab.
It is a sprawling complex of buildings set in the beautiful grounds of a historic building dating back to the Elizabethan period.
Facilities include a hydrotherapy pool, swimming pool, four fully equipped gyms and a state-of-the-art limb-fitting and amputee centre.
The centre has received many royal visits in recent years, most notably from the Duke of Cambridge, who opened some new facilities at the centre in 2010.
During their tour of Headley Court, the Queen and Duke will visit the Waterloo gym, where service personnel who have lost limbs will be put through their paces.
The royal visitors, who will stay for a private lunch, will also meet nursing staff and other patients before the Queen opens a refurbished unit.
