Is this "first hand" enough for you??
Army Chaplains are expected to observe the distinctive doctrines of their faith while also honoring the right of others to observe their own faith. The Army is a pluralistic environment. Rabbis, Ministers, Imams and Priests serve our Soldiers with conviction and commitment. While serving their own faith groups in the Army, chaplains also ensure and provide the means for others to observe their own faith in accordance with US law and regulations.
