Disambiguation: FOUO (For Official Use Only) is a US government protective marking for unclassified information, not a person, organization, or UAP-related entity. In the context of US Department of War/DoD documentation, FOUO designates information exempt from FOIA disclosure.
FOUO (For Official Use Only) is a protective marking and handling instruction used by the U.S. Department of Defense and other federal agencies to designate unclassified information that requires protection from public disclosure. Although unclassified, FOUO information is exempt from mandatory release under the Freedom of Information Act (FOIA) under exemptions 2-9. The formal consolidation of FOUO into the broader Controlled Unclassified Information (CUI) framework occurred on February 24, 2012, though the designation continued to appear in DoD documentation. FOUO materials require specific handling standards including conspicuous marking, secure storage, and encrypted transmission, with unauthorized disclosure potentially resulting in administrative or legal sanctions.
