The United Service Organizations Inc. (USO Show) is a nonprofit organization that provides programs, services and live entertainment to United States service members and their families.
For over 75 years, the USO has been the nationâs leading organization to serve the men and women in the U.S. military, and their families, throughout their time in uniform. From the moment they join, through their assignments and deployments, and as they transition back to their communities, the USO is always by their side.
