Abstract Many political theorists have argued that religious reasons should play a rather limited role in public or political settings. So, for example, according to the Doctrine of Religious Restraint, citizens and legislators ought not allow religious reasons to play a decisive role in justifying public policies. Many military professionals seem to believe that some version of that doctrine applies in military settings, that is, that military professionals should not allow their religious convictions to determine how they exercise command authority. (...) We explain why the Doctrine of Religious Restraint should not apply to military professionals and articulate an alternative understanding of the justificatory role legitimately played by religious considerations in military settings. This alternative understanding assumes that military professionals will exercise command authority with tact, wisdom, and due respect for both the spirit and letter of the law, even when they are guided by robust faith commitments.
