The response of military psychology in times of war or other great public crises may presage the success of the profession in less perilous times. The ability of public-sector psychologists to provide assistance and improve the common welfare during conflict or turmoil is generally followed by an increased demand for psychological services. This likely reflects the success of the psychological response during those crises, and it underscores the fact that psychological consequences of war or disaster require both immediate clinical attention and long-term policy development. The U.S. Navy serves as a model for public-sector psychological service provision. A brief history of Navy psychology is provided, followed by an examination of how Navy psychologists are responding to the issues raised by the current conflict in the Middle East and the problems associated with stigma in the treatment of posttraumatic stress disorder.
