American Women's Voluntary Services (AWVS) was the largest American women's service organization in the United States during World War II (WWII). AWVS provided women volunteers who provided support services to help the nation during the war such as message delivery, ambulance driving, selling war bonds, emergency kitchens, cycle corps drivers, dog-sled teamsters, aircraft spotters, navigation, aerial photography, fighting fires, truck driving, and canteen workers. Some of its work overlapped with the Office of Civilian Defense and the American Red Cross.
