John Keller writes that ONR wants to develop 14 types of non-lethal weapons, including human electro-muscular incapacitation, non-pyrotechnic flashbang and hail-and-warn devices.
Authorities use non-lethal technology to disable attackers, stop ground or marine vehicles, disperse crowds and control riots, according to Keller.
This kind of weapon is intended to cause temporary blindness, pain, confusion, disorientation or muscle spasm to an enemy, Keller says.
