A man-portable non-lethal pressure shield provides both a physical as well as pressure shield. The pressure shield addresses the concerns of military, police and human rights organizations and international law as regards effectiveness, efficiency and safety and efficiency. A folded acoustic horn is incorporated into the physical shell of the shield. The horn couples acoustic pulses from a sonic pulse generator to an acoustic aperture to output a pulsed pressure beam that approximates a plane wave to produce a pressure barrier. The operator may specify a desired effect on its human target that is maintained as range-to-target changes or a desired effect at a specified perimeter range. The shields may be networked to facilitate coordinated action among multiple pressure shields as a force multiplier or to provide a more sophisticated pressure barrier.
The purpose of the NLW Reference Book is to provide a single source document that contains key information about NLW descriptions, effects, characteristics, concepts of employment, and associated operational parameters and considerations to enhance NLW education and training.
Law enforcement officers of the 21st century encounter many of the same challenges and issues their predecessors faced during the late 20th century. Incidents involving hostage rescue, vehicle pursuit, attempted suicide, the need to detain or control unruly individuals and crowds, and domestic disturbances continue to dominate daily activities. However, technology advances have matured, and new tactics provide law enforcement officers with additional options for handling many of these situations. A difficult aspect of civil law enforcement continues to be the need to manage individuals or groups when more than a show of force or voice commands are required and deadly force is neither authorized nor the preferred method of resolution. To meet this need, many Federal and State agencies and local law enforcement departments have developed and used less-lethal technology.
