With a good selection process and a good assessment based on the symptoms of post-traumatic stress, I am not sure that you need to know if the person was abused sexually as a child, whether that is a risk factor or not. In fact, what we would want to know, three or four months after the person has returned from a mission, is whether he is exhibiting the symptoms of post-traumatic stress, whether he is clinically depressed, whether he is currently abusing alcohol, and so on. In the end, that is all you need to know about that individual.
