Phoenix JR.TM and the war on terrorism.
Since its introduction in 1984, the Phoenix JR.TM (Firefly)TM beacon has become the world standard for covert signalling and electronic combat identification of military, law enforcement, SWAT and homeland security assets. It has been utilised by American and coalition forces for combat identification in theatres of operation such as Kosovo, Bosnia, Somalia, Afghanistan and Iraq. These beacons have multiple uses in combat and other operations for marking personnel, vehicles, pathways and locations. They incorporate a flash rate that was specified to prevent confusion with small arms fire.
