This book takes an in-depth look at the function of public relations as it exists in the U.S. military in the 21st Century.There have been several books and journal articles covering the military/media relationship but none that delve into breadth and depth of the responsibilities of today's military public affairs officer. This book discusses the concept and foundations of military public affairs (relations), the changing strategic landscape in communications, operational planning and execution and the people who practice military public affairs. The goal is to broaden knowledge and understanding of this vital, but little discussed, area of public relations among civilian and military public relations and communications professionals, faculty and staff in public relations programs, military leaders, as well as the U.S. civilian populace, and research scholars specializing in military public relations or public affairs operations.
