The Civilian Public Service (CPS) was a program of the United States government that provided conscientious objectors with an alternative to military service during World War II. From 1941 to 1947, nearly 12,000 draftees, willing to serve their country in some capacity but unwilling to perform any type of military service, accepted assignments in "work of national importance" in 152 CPS camps throughout the United States and Puerto Rico. Draftees from the historic peace churches and other faiths worked in areas such as soil conservation, forestry, fire fighting, agriculture, under the supervision of such agencies as the U.S. Forest Service, the Soil Conservation Service, and the National Park Service. Others helped provide social services and mental health services.
