Yes, participation is mandatory now, which makes doing any further studies and evaluations problematic, obviously. What we're trying to do is to see whether or not we can add elements to the battlemind training to even further improve its effectiveness. We're doing that now.
I should say that we're also working with the United Kingdom, the Brits, because they don't have any mandated mental health training programs, but are actually in the process of designing a study to look at whether or not the program would be successful with British troops coming back from Afghanistan and Iraq.
