Rhodes has taught philosophy and professional ethics for over 16 years to military service members. Here, he offers an introduction to the study of military ethics, written for military officers, policymakers, and students. After a review of fundamental concepts, he focuses on the legacy of the "just war theory" and its application through history, then examines the application of that tradition in the modern era, with discussion of the use of military force in the name of a political community, and the ethical underpinnings of the rules of warfare. He also looks at emerging controversies faced by modern militaries, such as humanitarian intervention and dealing with nonstate actors, such as terrorists. Final chapters look at cultural issues in the modern military, including integration of women into the services, and address issues of professional identity. A glossary and a chronology are provided.
