As all those Marines in my company began filtering out, some from essential positions, I started to worry about the welfare of those remaining. I worried, quite naturally, that if the exodus continued, we might not have enough to accomplish our mission or to survive on the battlefield. My sympathies for those individuals claiming post-traumatic stress began to wane. A commander cannot serve in earnest both the mission and the psychologically wounded. When the two come in conflict, as they routinely do as a result of repeated deployments, the commander will feel an internal and institutional pressure to maintain the integrity of his unit. I did. And there begins a grassroots, albeit subconscious, resistance to Mullen's plan to destigmatize the people who seek help. Because as much as I cared about my Marines, it was difficult to look upon those who sought to leave without suspicion or even mild contempt.
