The Department of Defense calls it Silent Sound Spread Spectrum (SSSS),

and it also goes by the name of S-quad or Squad.

In the private sector, the technology goes by the name of Silent Subliminal Presentation System

and the technology has also been released to certain corporate vendors who have attached catchy brand names like BrainSpeak

Silent Subliminals to their own SSSS-based products.

Whatever you call it, SSSS is a technology that uses subliminal programming that is carried over Ultra-High Frequency (UHF) broadcast waves,

planting inaudible messages directly into the subconscious human mind.

( Americans tend refer to American People as everyone! EG USA = US = The World! )

Completely undetectable by those being targeted.

Because it delivers its subliminal programming directly to the human brain via the auditory sense at frequencies

that humans are incapable of perceiving as sound, there is no defense against it.
