Some of the largest military support organizations are the United Service Organization and the Wounded Warrior Foundation. Many military support organizations focus efforts on veterans health services, including transition from deployment back into civilian life, such as the U.S. Department of Veterans Affairs and the Veterans of Foreign Wars organization.
The USO originates from an organization composed of some American charitable organizations that banded together prior to the United States' involvement in World War II. The organization now operates throughout the United States and various international U.S. military stations to provide support and crucial services to members of the military and their family members.
The U.S. Department of Veteran Affairs is one of several federal agencies operating in support of the armed forces and their veterans. These agencies offer services such as health care and financial support, and provide grants to private and nonprofit support organizations.
Organizations like the Wounded Warriors Foundation, Veterans of Foreign Wars and other similar groups provide more specific services to past and present servicemembers, operating by way of charitable donations and fundraising efforts. Online charity directories like CharityNavigator.org offer focused directories of many large military support organizations, as well as financial information about the groups, dependability scores and whether or not certain organizations have been recommended by other users.
