The book opens with the core question which lies at the heart of the matter - what happens religiously to America's warriors when they go to battle, and what impact does this have on the nation's conduct of war? Mansfield surveys America's wars from a theological perspective in order to understand the theological framing and religious rationale for each, where they came from, and what effect they had on behavior on the battlefield. Mansfield examines the religious nature of the warrior ethic today. There is a new generation on the battlefield now, one raised with less religious training and less connection to history than any that has come before. Soldiers are left to their own religious choices to frame their moral perspectives on war, on killing, and on the possibility of death.
