Initiated in 1950, this 2007 edition is the latest in a classic series of books of the same title. Journalist-historian S.L.A. Marshall wrote the first at the behest of Gen. George C. Marshall, who formed the great citizen army of World War II. The general believed officers of all services needed to base their professional commitment on a common moral-ethical grounding, which S.L.A. Marshall set out to explain. Ever since, these books have provided a foundation of thought, conduct, standards, and duty for American commissioned officers.Available now to the general public, this new edition takes the series' inspirational premise into the new century. It educates officers of all services, as well as civilians, about the fundamental moral-ethical requirements of being a commissioned officer in the armed forces of the United States. Understanding the common foundation of commissioned leadership and command of U.S. military forces is essential for achieving excellence in the joint operations of today's combat environment. This philosophy unites the officers of the uniformed services in the common calling of supporting, defending, and upholding the Constitution in service to their country.
