Let me give you some data that we collected about six months ago looking at our pre-deployment training.
By the time the program came out a year ago, obviously a lot of soldiers had deployed to Iraq and didn't get the battlemind pre-deployment training, and some soldiers did get the pre-deployment training before they deployed to Iraq. While the soldiers were deployed--this was during the deployment--we did a survey and evaluation of the mental health status of the deployed force in Iraq. Of those soldiers who did not receive the battlemind training, about 20% to 22% screened positive for post-traumatic stress disorder. For those who did receive the battlemind training, only about 12% screened positive for post-traumatic stress disorder.
The number is still not zero, so it's not the silver bullet. It's not that you do this training and you are not going to have any mental health problems, but it does significantly reduce the symptoms for post-traumatic stress disorder.
Sir, I would just like to say that I completely agree with you that post-traumatic stress disorder is an injury, and it should be viewed as an injury. I don't know if you're following it at all, but within the U.S. military there's a very big debate going on concerning whether or not the Purple Heart should be awarded for psychological injuries just as it is for physical injuries. As you can imagine, those veterans who were physically wounded are not terribly supportive of that proposition, but it is being discussed.
