US diplomats and intelligence officers (Havana from late 2016, then worldwide) reported sudden pressure, sound, vertigo and lasting cognitive symptoms. The March 2023 ICA (7 agencies): foreign-adversary involvement 'very unlikely', with no credible evidence of a weapon (some agencies at low or moderate confidence). The House Intelligence Committee (2024 interim) called a foreign adversary increasingly likely. NIH (Mar 2024): severe symptoms but no MRI-detectable injury. Jan 2026: DHS-HSI covertly bought, for ~$15M (Pentagon-funded), a backpack-sized pulsed-RF device with Russian components from a Russian criminal network; the Pentagon has been testing it for over a year. Jun 2026: DNI Gabbard rescinded two Biden-era AHI assessments for faulty tradecraft; the FY26 NDAA mandates standard AHI reporting.
