Retired Army colonel, UAP Task Force liaison (2021-22); on-record corroborator who called Grusch's reverse-engineering claim 'fundamentally correct.'.
Real Army intelligence officer and aerospace executive who worked with Grusch on the UAP Task Force. In The Debrief's June 2023 exposé he stated the sub-rosa reverse-engineering 'arms race' is fundamentally correct and that some technologies 'derive from non-human intelligence,' later repeating NHI assertions at the 2024 SALT conference. His role and statements are documented; the corroboration is testimonial, not physical evidence.
