"Silent Guardian" - "Acoustic Blaster" - oooohhhh crap

$25M contract ready for deployment soon.

Silent Guardian weighs a shade over 10,000 pounds all up, and will be mounted on an "armored ruggedized HEMTT [Heavy Expanded Mobility Tactical Truck]."

The announcement arrives on the same day as a new report from less-lethal weapons expert Dr. Jürgen Altmann that analyzes the physics of several directed energy weapons, including Active Denial, the Advanced Tactical Laser (used as a non-lethal weapon), the Pulsed Energy Projectile (a.k.a. "Maximum Pain" laser) and the Long Range Acoustic Device (a.k.a. "Acoustic Blaster").
