But let's looks back to the USSR, which, after the end of World War II, began its arms race with USA. Both countries worked on developing weapons that could subjugate people to their will - simply speaking, turn huge masses of people into obedient and docile zombies. Whereas in the US the project was given the name of "Clean Brain," in Soviet Union it was called "Radio Sleep", its basis founded in Kajinsky's "Brain Radio" and the work of other researchers, all sent off to be archived before the war.
In 1954, by the order of USSR's Minzdrav (The Ministry of Health), there was established a laboratory for a special force for psychological research - abbreviated as PION. The researchers divided into two factions, named Pionists and Pioneers respectively. The former insisted on zombification of people through the use of specialized equipment that would send a signal which would influence a person's brain and could cause a wide spectrum of possible effects, from deep sleep to a variety of behaviors. The latter faction, on the other hand, believed in the use of psychotropics and hallucinogenics which would be spread over an area occupied by enemy forces.
