"Doughboys" is a term used to refer to American soldiers who served in World War I. The nickname is believed to have originated from the round, dough-like buttons on their uniforms or from the flour used in the food they ate. Doughboys played a crucial role in the war, contributing to the Allied victory against the Central Powers. These soldiers were primarily drafted or volunteered from various backgrounds across the United States. They faced harsh conditions in the trenches of Europe, where they encountered new warfare technologies, such as machine guns and poison gas. The experiences of the Doughboys significantly shaped American military history and public perception of the war.
