Homeland Security's "Invisible Weapons": What Technology Could They Be Using?

May 2025 reports revealed Homeland Security's admission of using weapons that cause psychological effects "with no entrance or exit wounds,that can make the subject (target) go crazy" Here's a breakdown of the likely technologies behind these systems:

1. Directed Energy Weapons (DEWs)

  • Microwave Systems: Like the Active Denial System, causing intense skin heating and psychological stress
  • Voice-to-Skull (V2K): Pulsed microwaves creating auditory hallucinations (cf patent DE10253433A1)

2. Sonic/Ultrasonic Devices

  • Infrasound (below 20Hz) inducing nausea/fear
  • LRADs causing anxiety through high-decibel sound

3. Electromagnetic Brain Stimulation

  • Weaponized TMS disrupting neural activity
  • PEMFs altering brainwave patterns

4. Psychotronic Neuroweapons

  • Subliminal audiovisual entrainment
  • Experimental "synthetic telepathy" systems

Key Considerations

  • Most technologies are dual-use (civilian/military)
  • Psychological effects ≠ physical damage
  • Ethical concerns about neuroweaponization
