Perhaps I'll preface my comments by saying that of those in service and post-service who suffer from mental health problems as a result of service, post-traumatic stress disorder is a very rare occurrence. It's not even nearly the most common kind of mental health problem. Depression and other issues are more common. My military colleagues in service have been working hard to improve the level of provision for mental health services in service.
We have two elements to that. One is a program called TRiM. It's not a medical intervention but it's an awareness program, a support network that soldiers use among themselves. There are trained staff to help facilitate this. One element is prevention, understanding, and raising awareness, and that's through a program called TRiM. But we equally deploy specialist teams to operational theatres to help support people in theatre, as well as remove people from operational theatres if that's a more appropriate course. So in service there is the whole normal range of medical interventions one might expect to be provided on a normal evidence base to support people in service who have suffered mental health problems.
When people leave service that becomes the responsibility of the National Health Service. We have a range of programs in place with them to improve the provision that's available there.
