U.S. Department of the Army, Feb 17, 1998
This 17-page report was de-classified and released to the public in December, 2006 due to a Freedom of Information Act request.
“This addendum to the “Nonlethal Technologies–Worldwide” (NGIC-1147-101-98) study addresses in summary, some of the most often asked questions of nonlethal weapons technology .. These results identify and validate some aspects of maturing nonlethal technologies … including
· Laser and other light phenomena.
· Radiofrequency directed energy.
· Aural bioeffects.”
The document is interesting to read, particularly the section discussing pulsed EMR. Since the military invested considerable funding over many years for research on EMR weapons development, there may be many more useful reports that have yet to be de-classified and released to the public.
