Harry Redknapp, Michael Dawson and Jermain Defoe made a special trip to Defence Medical Rehabilitation Centre Headley Court in Epsom, Surrey on Tuesday afternoon.
Headley Court provides treatment and care for members of the British Armed Forces that suffer with physical disabilities and post-traumatic stress disorder as a result of conflict.
Harry admitted the visit was an uplifting experience for everyone.
"We all sit at home, watch TV and it is just so sad to hear what has happened to some of these young boys and what their families must be going through," said Harry.
"To come and try and lift their spirits is just an absolutely fantastic experience. It is just amazing to see the attitude of these boys. They have been through so much and suffered terrible injuries.
"Just what these boys are doing for their country and how they cope with their lives with such serious injuries is a lesson to all of us. When we moan and get miserable about the minor things in life, to see how these boys are coping they really are a credit to their country.
"They were pleased to see the lads because they love their football. I think it would be great for any footballer to come and see these lads to realise just how lucky we all are and the courage that these boys have shown."
