Whistleblowers & Witnesses
Matthew Brown
2024
Former Pentagon contractor/analyst (Office of the Under Secretary of Defense for Intelligence; WMD portfolio; TS/SCI via DIA) who, in April 2025 on Corbell & Knapp's “WEAPONIZED,” publicly identified himself as the anonymous author of the “Immaculate Constellation” report that reached Congress in 2024. Says that c.2018 he glimpsed a ~12-slide file referencing the “2018 Schriever Wargames” describing an AI system that scrubs military surveillance feeds for UAP imagery, and reconstructed the report from memory years later. Single-source and uncorroborated — the Pentagon found “no record” of the program and skeptics note the source file was labeled a wargame. (Claims contested.)
