ATCO American Technology (MM)

American Technology Corporation (ATC) (NASDAQ: ATCO), the innovator and distributor of the Long Range Acoustic Device(TM) (LRAD®) product line, announced today it has received a follow-on LRAD 500X(TM) order totaling approximately $1.6 million from the U.S. Army Reserves. ATC announced the initial order last month (http://www.atcsd.com/site/content/view/310/55/). Both orders are scheduled to ship this quarter.

The LRAD 500X can be mounted on a variety of military vehicles including the HMMWV, LMTV, FMTV and MRAP, providing soldiers the critical capability of clearly broadcasting information, instructions and warnings to distances in excess of 2,000 meters from within their vehicles.

"We continue to support our armed services in their peacekeeping missions around the world through increasing LRAD shipments," remarked ATC president and CEO, Tom Brown. "With further LRAD orders expected from the U.S. Military and other organizations and agencies this quarter, we're off to a strong start in fiscal 2010."

ATC's proprietary LRAD directed sound systems enable military forces to communicate clearly and determine the intent of potential threats at safe distances, providing time and distance to employ a measured response to a threat's actions. Through the use of focused multi-lingual voice commands and deterrent tones, LRAD creates increased standoff and safety zones, supports conflict resolution, and potentially saves lives on both sides of the device.
