AEF (American Expeditionary Force)

The American Expeditionary Force (AEF) was the primary military organization of the United States during World War I. Established in 1917, it consisted of American troops sent to Europe to support the Allies against the Central Powers. Led by General John J. Pershing, the AEF played a crucial role in several major battles, helping to turn the tide of the war. The term also reflects the U.S. commitment to international cooperation and collective security, marking America's emergence as a significant player on the world stage. The AEF helped shape modern U.S. military policy and diplomacy.
