It is so dependent on how they come in. We have done a lot of work with people from every tour. We're getting some people who have come in 11 years post-tour. By that time, you know it's going to take a long time.
I think perhaps with Afghanistan we may be able to get some idea of that. But again, we're getting people coming in who have had multiple tours and multiple traumas, so it is very case-specific.
