Can you explain to us what research you and these five investigators did? Did you speak to the superior officers in the chain of command? Did you speak with soldiers who have come back and who do not suffer from post-traumatic stress disorder? Did you speak with soldiers who are victims of this disorder? Did you speak with their families? How big a sample did you use? Is it similar to what I have just described to you or does it go beyond that?
