US military sets laser PHASRs to stun

New Scientist Breaking News

The US government has unveiled a "non-lethal" laser rifle designed to dazzle enemy personnel without causing them permanent harm. But the device will require close scrutiny to ensure compliance with a United Nations protocol on blinding laser weapons.

The Personnel Halting and Stimulation Response (PHASR) rifle was developed at the Air Force Research Laboratory in New Mexico, US, and two prototypes have been delivered to military bases in Texas and Virginia for further testing.

The US Department of Defense (DoD) believes the weapon could be used, for example, to temporarily blind suspects who drive through a roadblock. However, the DoD has yet to reveal details of how the laser works and has yet to respond to New Scientist’s requests for further information.
