The 8th Infantry Division, ("Pathfinder") was an infantry division of the United States Army during the 20th century. The division served in World War I, World War II, and Operation Desert Storm. Initially activated in January 1918, the unit did not see combat during World War I and returned to the United States. Some units would serve in the American Expeditionary Force to Siberia. Activated again on 1 July 1940 as part of the build-up of military forces prior to the United States' entry into World War II, the division saw extensive action in the European Theatre of Operations. Following World War II, the division was moved to West Germany, where it remained stationed at the Rose Barracks in Bad Kreuznach until it was inactivated on 17 January 1992.

The American Expeditionary Force, Siberia was a formation of the United States Army involved in the Russian Civil War in Vladivostok, Russia, after the October Revolution, from 1918 to 1920. The force was part of the larger Allied North Russia intervention. As a result of this expedition, early relations between the United States and the Soviet Union were poor.
