The State Guard Association of the United States (SGAUS) is a non-profit organization advocating for the advancement and support of regulated state military forces, as established by state governments under the authority of federal law. The SGAUS encourages the establishment and advancement of regulated state forces through lobbying and affiliation with independent state associations. There were twenty-two independent SGAUS recognized state associations in 2008. State associations are separate entities—typically 501(c)(3) corporations—and are not components of the SGAUS corporation, the SGAUS Foundation, or the respective states. When petitioned, the SGAUS recognizes lawful, state-level associations with twenty-five or more members who are seeking to establish state defense forces.
