The United Services Organization, better known as the USO, was a volunteer organization formed in 1941 that focused on entertaining and comforting American troops overseas during and after World War II. In 2375, during the Dominion War, after recording a few songs for Julian Bashir on an isolinear rod, Vic Fontaine offered to put together a regular USO show for the war-weary Starfleet troops who were about to make a supply run to AR-558.
