In recent attempts to develop weapons that are nonlethal but still able to incapacitate opponents, the military has turned to a new technology called an “LED Incapacitator.”
This device uses light-emitting diodes, or super-bright pulses at quickly altering wavelengths, which causes immense disorientation and unbalance. As the light changes, the person is so disconcerted that nausea sets in and they start to vomit.
The device looks like a large flashlight, which may appear to be nonthreatening, but after only a few seconds it has anyone looking into it vomiting profusely! The military hopes to implement technologies such as this for missions with large civilian populations around or when a capture is intended.
