97th Infantry Division (United States)

The 97th Infantry Division was a unit of the United States Army in World War I and World War II. Nicknamed the "Trident division" because of its shoulder patch, a vertical trident in white on a blue background. It was organized in New Mexico in September 1918, where it was ordered to be demobilized – before having reached its full complement – nine days after the Armistice of 11 November 1918. It was reconstituted in February 1943, and was originally trained for World War II in amphibious assaults, as preparation for deployment in the Pacific Theater. Instead, it was deployed to Europe in 1944 when casualties from the Battle of the Bulge needed to be replaced.

Since 3 November 2010 the division's heritage is continued by the 97th Training Brigade at Fort Sheridan.
