Service Organizations，USO) 成立
When a World War II soldier received a needed break from fighting, where could he go and what could he do? A solution to this problem came with the formation of the United Service Organizations, popularly known as the USO, on February 4, 1941. Its mission was to provide recreation for on-leave members of the U.S. armed forces and their families. USO recreational clubs supplied a place for everything from dancing, movies, and live entertainment to a quiet place to talk, write letters, or find religious counsel.
