I'm not sure what we have done that's new. It's something that's implicit in part of the make-up of the platoon, the companies and battalions when they deploy, that there are medics, physician assistants, a battalion doctor. Of course the leadership and the soldiers themselves are now much more trained to understand and be aware of more social and psychological issues. If there is an issue that comes up, then we have a process whereby the medic or the physician assistant will determine whether or not it's something they can handle. There's a protocol for that kind of stuff. If not, there's a natural referral process.
Of course, as you know, we try not to, again, stigmatize mental health issues in the battlefield by sending them back to the rear echelon and punting them home right away. This is something that was well delineated during the First World War and the Second Word War. You have to treat them as close to the front as possible. If you bring them home, the chance of their going back to duty becomes dramatically less. The idea is to provide therapy as close to the front line as possible, and because of that, as you know, we deploy a mental health team, a social worker, a mental health nurse, and a psychiatrist in theatre so that if a high level of care is needed, it can be done on-site and then the soldiers can go back into their battalion and become combat capable. This is something that was in the SOP right from the beginning. We've continued to do that.
Of course, if somebody does have an issue, their file is flagged, and when they come back they're followed up. If you look at the statistics, the number of people repatriated in theatre because of that is extremely small.
