While some military atheists contend differently, a Mental Floss writer has started to compile short stories of heroic US military chaplains, well back into US history.  The author notes

Military chaplains are classified as non-combatants, but they still put their lives on the line to serve their country and its military members—and often civilians and enemy soldiers, too. Many went above and beyond the call of duty, and their stories should be remembered.

Worth a read, in Parts One and Two.
