"The American Expeditionary Force"

The American Expeditionary Force (AEF) was the name for the U.S. military forces sent to Europe during World War I, beginning in 1917. Under General John J. Pershing, it comprised mainly of American soldiers who arrived to support the Allies—Britain, France, and others—in their fight against Germany. The AEF played a crucial role in turning the tide of the war, helping to secure victory and shaping the future of U.S. military involvement. It marked the first significant large-scale military effort by the United States abroad, establishing its role as a major global power.
