Using Long Range Communication
in EOF

The role of Defence forces in conflicts has evolved toward greater emphasis on managing interaction with civilian populations. Defence organizations around the world are using Long Range Acoustic Devices to fill the critical gap between initial engagement and employing lethal force. Since LRAD was first introduced in 2003, the product line and applicable missions have expanded to become a vital part of layered defence and attack strategies for land forces around the world. LRAD has saved the lives of soldiers and innocent civilians and enabled maneuver forces to quickly make accurate life or death decisions, to stand down or open fire.



As part of a layered communication and EOF strategy, LRAD systems provide defence personnel time and distance to distinguish between security threats and innocent civilians before employing lethal force. At distances ranging from 200 meters up to 3 kilometers, LRAD systems broadcast focused (15°-30°), highly intelligible multilingual hails, warnings and commands to security threats or large crowds. LRAD also broadcasts powerful deterrent tones to initiate the EOF based on a threat’s actions.

Through the use of voice commands and deterrent tones, LRAD unequivocally determines intent at distance and is an essential component in all EOF protocols. Thousands of LRAD systems have been deployed in over 70 countries worldwide with proven performance and reliability in all types of weather conditions and environments. Portable LRADs range from the handheld LRAD 100X weighing just 7 kgs to the LRAD-1000Xi with an audible broadcast range up to 3000 meters.

Every LRAD comes with an all-weather microphone and LRAD’s MIL SPEC MP3 player to record and playback messages on the fly or to broadcast live or pre-recorded warnings, commands and messages in any language for any operational scenario.

LRAD systems are the most thoroughly tested acoustic hailing devices (AHDs) on the market, having successfully passed approximately 40 separate U.S. government tests including all MIL STD testing for heat, humidity, and shock. LRAD systems feature rugged military construction and have been tested and approved by ARDEC and the Aberdeen Test Center.

U.S. Army’s AHD of Choice – LRAD 500X


In 2005, the Army and the JNLWD, in conjunction with CASCOM, identified a critical capability gap. Their analysis found that soldiers could not adequately communicate in host nation language from a safe distance to adequately limit EOF. Soldiers were being placed in situations where they could only choose to shoot or not shoot, resulting in many unnecessary indigenous civilian casualties. Other non-lethal tools failed to provide adequate direction to inform civilians what they needed to do to avoid EOF and potentially lethal consequences.

Early AHDs had previously been provided in Army EOF kits, but Army testing revealed they were inadequate to effectively communicate beyond the typical standoff firing range during convoy protection, at entry control points, for crowd control, and on FOB perimeters. To address this capability gap, the Army and JNLWD went to industry sources, including LRAD Corporation, and asked them to develop a communications tool that could communicate up to 300 meters over 88dB of background noise. The LRAD 500X won an extensive  AHD competition to become the Army's solution.

The LRAD 500X has Army safety certification and has successfully completed a full battery of tests at Aberdeen Test Center.

Systems have been fielded on FOBs, MRAPs, LSVs, LCUs and at ECPs around the world.
