China in the third week of December 2014 developed a long-range and non-lethal Pain Beam weapon named Poly WB-1. The weapon can be used to break up riots or protests from a distance.
The Poly WB-1 was unveiled at an air show in China and it uses a millimeter-wave beam that can travel distances of up to One kilometer.
China developed the weapon for naval applications to deal with confrontation in non-lethal ways. The WB-1 will be mounted in ships, majorly in those patrolling disputed waters.
Poly WB-1 is similar to the Active Denial System (ADS) created by Raytheon, which was sent to Afghanistan with the United States military, but was not used in combat and recalled in 2010.
How it disperses crowd?
Once the beam comes in contact with a person, the beam disperses the crowd through heating up water molecules just below the skin causing intense pain resulting into recoiling of the person. But if longer busts are made at certain frequencies, it will cause the flesh to burn and blister.
