The Tenth Army was a military formation of the United States Army during World War II. It was primarily active in the Pacific Theater and played a significant role in the campaign to capture the island of Okinawa in 1945. The army was known for its combined arms operations, integrating infantry, armor, and air support to achieve its objectives. Commanded by General Simon Bolivar Buckner Jr., the Tenth Army was involved in one of the war's bloodiest battles, facing fierce resistance from Japanese forces. The successful capture of Okinawa was crucial for the Allies, as it provided a strategic base for future operations against Japan.
