Our Mission: The USO keeps America's military service members connected to family, home and country, throughout their service to the nation. The USO is a family of volunteers, sustained by the charitable contributions of millions of generous Americans. We are united in our commitment to support America's service members by keeping them connected to the people, places and things they love. We do this through countless acts of caring, comfort, connection and support. Our work is America's most powerful expression of gratitude to the men and women who secure our nation's freedoms.
