40th Infantry

The 40th Infantry Regiment was constituted on 15 May 1917 in the Regular Army of the United States during the build-up for World War I. Organized at Fort Snelling, Minnesota, the unit did not see combat during the Great War but served as a training and replacement regiment. After the war, the 40th Infantry was stationed at various posts before being inactivated in 1921 at Fort Snelling. Though reactivated briefly during World War II, it was ultimately disbanded in 1944 as the Army reorganized its forces for the changing needs of the conflict.
