The AG does not prohibit military service and has historically supported military chaplaincy, with AG credentialed ministers serving as chaplains in all branches of the U.S. armed forces. The AG Chaplaincy program is one of the denomination's recognized ministries, reflecting its view that Christians can honorably serve in the military.

The AG stands within the just war tradition common to mainstream evangelical Christianity: military service may be an honorable calling when conducted for legitimate purposes of defense and justice. The denomination does not mandate conscientious objector status, though individual members who hold pacifist convictions based on their reading of Scripture are respected.

The AG's patriotic and civic engagement has traditionally been strong in the United States, and many of its congregations honor military veterans. The denomination has not issued extensive formal statements on just war theory but operates in practice within the mainstream evangelical consensus that military service is compatible with Christian discipleship.
