In terms of the follow-up, we have a series of follow-ups. As you pointed out, it's important that you can't only have one because you could miss people. Immediately on your return, in the third location decompression, there's an opportunity for people. They will sign a declaration and identify any high-risk involvement they've had with any other traumas, combat, and so forth that would identify them as being in the higher risk population. Then when they get home, anybody who's been identified at that point is picked up and immediately referred.
After that we do our enhanced post-deployment screening, which takes place anywhere from four to six months after their return, where they do a very in-depth questionnaire about anything related to mental health. They also have a personal interview with a mental health care provider. That's an opportunity for somebody to tease out a little bit more information. On top of that we have routine periodic health examinations that also go through and do extensive screening for any type of mental illness.
