As a member of the commander's staff, chaplains serve as moral, ethical, and spiritual advisers to their commanders. They ensure the free exercise of religion and oversee the unit and base religious programs. Much of the work they do is one-on-one with the soldiers and their families. Chaplains go where the troops go. They are in the barracks, in the offices, and in the training areas, as well as in combat zones ministering to men and women of all faiths, denominations, and persuasions. They must be able to work in a pluralistic religious environment, respecting and accommodating members of all faiths without compromising their own beliefs. Chaplains serve full-time in the active-duty Army, Navy, Air Force, Marine Corps, and Coast Guard. In addition, they can serve part-time in the Reserve and National Guard while pursuing other forms of civilian employment. As with all Reserve and National Guard members, if the unit is activated, they may have to deploy for extended periods of time.
