After entering the service, Frederick was assigned to C Company 116th Infantry. He sailed with the unit for France aboard the USS Finland. The ship departed Hoboken, New Jersey on 15 Jun 1918 and arrived at the port of Saint Nazaire, France on 28 Jun 1918. The entire division went through training in trench warfare and acclimatization in a "quiet" sector on the front lines before participating in a major offensive. Starting on 8 Oct 1918 in the vicinity of Verdun, the regiment experienced intense fighting. PFC Green was killed in action on 16 Oct 1918.
PFC Green rests forever in the Meuse-Argonne American Cemetery.
Frederick's older brother, William Ernest Green, also served during the war.
