World War I
The Graves registration service was created by General Order #104, issued on August 7, 1917, four months after the United States entered World War I. It consolidated the existing departments into the Graves Registration Service. At its inception, the Graves registration service consisted of the 301st, 302nd, 303rd, and 304th Grave Registration Units. They were deployed to Europe during the war. Many of the men that served in these units had been incapacitated for field service.
