World War I: The regiment was constituted on 11 May 1917 in the Regular Army and organized on 1 June 1917 at Fort Snelling, Minnesota. It was assigned to the 9th Division, though it remained in the United States throughout World War I, serving as a training unit and never deploying overseas.

Post World War II: The 313th Infantry Regiment saw extensive action in Europe during World War II. The lineage of the 42nd Infantry Regiment, through the 3rd Battalion, 313th Infantry, continues to be maintained. It has been associated with various reserve and National Guard units, reflecting changes in the US Army's force structure.

Modern Era: While the exact current configuration and deployment status may vary, elements tracing their lineage back to the 42nd Infantry Regiment continue to serve in the Army National Guard, contributing to homeland security and potentially deploying overseas as needed.
