The Thirty-Third Infantry Division was a unit of the United States Army that played a significant role during World War I and World War II. Formed in 1917, it was composed mainly of soldiers from the Midwest, particularly from states like Illinois, Indiana, and Wisconsin. The division was known for its distinctive shoulder patch featuring a red and white design. During World War II, the Thirty-Third Infantry Division was activated again and served in the Pacific Theater. It participated in several key battles, contributing to the Allied efforts in the region. The division was deactivated after the war, but its legacy remains an important part of military history.
