How does religion affect the lives of professional soldiers? How does religion shape militaries, their organization, procedures, and performance? This volume is the first to address these questions by comparing religious symbols and practices in nine countries: Japan, Canada, the United Kingdom, Pakistan, Israel, Iran, India, the United States, and Turkey. The contributors explore how and why soldiers pray, the role of religious rituals prior to battle, the functions that chaplains perform, the effects of religion on recruitment and unit formation, and how militaries grapple with ensuing constitutional dilemmas.
