It's a really good question.
There is not a lot of really solid evidence yet. However, we do have some, and we've based our programs on them. We know that no matter how terrible the situation is going to be, it seems that the more prepared people are ahead of time, the less traumatized they are. Surprise in and of itself produces trauma. Our whole road to mental readiness program that we devised, which I think you've heard about before, really comes out of that body of research.
So we prepare people just in the same way that we prepare them to go out with their company and fight. I'm thinking about Afghanistan. We also prepare them mentally by teaching them some techniques they can use when they find themselves feeling overwhelmed or getting very anxious as well as some things that will help them to calm themselves and calm their bodies down.
