The United States Boy's Working Reserve was an army of patriotic volunteer boys and men between the ages of sixteen and twenty-one years and organized under the United States Department of Labor.
Established in May 1917, to help the nation's farms and factories increase production during the First World War. All boys and men physically fit and of proper age, were eligible for this non-military civilian organization, which was broken into three units:
Agricultural, Industrial and Vocational.
The Reserve proved to be so valuable to the war effort, it was continued through 1918. Called the "Army behind the Army."
