Soldiers of Faith: is a 30-minute video that tells the story of a group of Anzec chaplains who served in the Australia/New Zealand military during WW I. Those chaplains came from Catholic and Protestant backgrounds. They put their lives on the line in serving Christ during a time of war. As this was service during WW I, and in the military other than the United States, there are some differences today in how U.S. Military chaplains serve. However, their story is informative and of value. The link below takes you to the 30- minute video.
