"In order for me to do my job as effectively as possible I need to be not expecting to come home"
These are the sacrifices service men and women make every day, particularly this former paratrooper AND Paralympian, Scott Meenagh.
He and Chris Ryan share a bond over Chris's brother, who served alongside Scott in the 2nd Battalion, Parachute Regiment. Scott lost both his legs in 2011 after stepping on an IED, but turned his life around to become a successful Paralympian.
