The experience of American Adventists during World War I generated several lessons which shaped the church's response to the draft during World War II, the Korean War, and the Vietnam War. First, Adventists working in the Medical Corps (United States Army) experienced the fewest conflicts regarding the keeping of Sabbath and bearing of arms. Second, pre-induction military medical training enhanced the effectiveness of Adventists who did serve and reduced the problems they faced. Third, educating church members regarding their obligations to both God and society reduced the extremism which often led to courts-martial.
