The United Service Organizations Inc. (USO) is an American nonprofit-charitable corporation that provides live entertainment, such as comedians, actors and musicians, social facilities, and other programs to members of the United States Armed Forces and their families. Since 1941, it has worked in partnership with the Department of War, and later with the Department of Defense (DoD), relying heavily on private contributions and on funds, goods, and services from various corporate and individual donors. Although it is congressionally chartered, it is not a government agency.

Liberty ships were a class of cargo ship built in the United States during World War II under the Emergency Shipbuilding Program. Although British in concept, the design was adopted by the United States for its simple, low-cost construction. Mass-produced on an unprecedented scale, the Liberty ship came to symbolize U.S. wartime industrial output.
