Clayton Slack joined the United States Army from Madison, Wisconsin in September 1917. He was assigned to the 33rd Division. He volunteered for machine gun duty and served with the Company D, 124th Machine Gun Battalion, 33rd Division.

As a private, he was cited for single-handedly clearing out a German machine gun nest resulting in 10 prisoners and the capture of 2 machine-guns on October 8, 1918, in the Meuse–Argonne offensive, the biggest battle of World War I involving American troops.
