MRAD LRAD
MRAD

As a side note, we recently fielded a Medium Range Acoustic Device (MRAD) that is lighter and more portable than the LRAD while delivering the same level of clarity and intelligibility at extended ranges. In other words, we heard the requirement for smaller and lighter and we have delivered.

LRAD

Tests proved that a broadcast could be heard clearly by a dismounted unit in a cemetery over 1,400 meters distant from the LRAD’s position. The LRAD runs on A.C. power but is adaptable. During distance tests at 100 meters., the sound was painful to listeners, even with hands held over the ears and ear plugs in. At 300 meters, they could understand every word, still with his hands over plugged ears.At 800 meters, they could hear every syllable through ear plugs. The LRAD was deployed atop Tall’Afar Castle, overlooking the al Sarai neighborhood. The first time it was used Iraqis walking the streets stopped and stared. Impact indicators went through the roof and Iraqis were seen writing down the counter-terrorism tip-line number at over 600 meters range. The LRAD has proven useful for clearing streets and rooftops during cordon and search, for disseminating command information, and for drawing out enemy snipers who are subsequently destroyed by our own snipers.
