Storm Trooper, or U.S. Air Force personnel? Getting hard to tell. From the Kirtland Air Force Base Web site:
Personnel Halting and Stimulation Response (PHaSR)
The Personnel Halting and Stimulation Response (PHaSR) is a rifle-sized laser weapon system that uses two non-lethal laser wavelengths to deter, prevent, or mitigate an adversary’s effectiveness. The laser light generated by this weapon illuminates or “dazzles” aggressors, temporarily impairing individuals and their ability to see the laser source.
