Using the codes eases coordination and improves understanding during multiservice operations. The codes are intended for use by air, ground, sea, and space operations personnel at the tactical level. Code words that are followed by an asterisk (*) may differ in meaning from NATO usage. There is a key provided below to describe what personnel ...

Sonar systems are generally used underwater for range finding and detection. Active sonar emits an acoustic signal, or pulse of sound, into the water. The sound bounces off the target object and returns an echo to the sonar transducer. Unlike active sonar, passive sonar does not emit its own signal, which is an advantage for military vessels.
The device works by emitting an ultra-high frequency blast (around 19–20 kHz) that teenagers or people under approximately 20 are susceptible to and find uncomfortable. Age-related hearing loss apparently prevents the ultra-high pitch sound from causing a nuisance to those in their late twenties and above, though this is wholly dependent on a ...

Sonar uses sound source localization techniques to identify the location of a target. 3D sound localization is also used for effective human-robot interaction. With the increasing demand for robotic hearing, some applications of 3D sound localization such as human-machine interface, handicapped aid, and military applications, are being explored.
The Fleet Sonar School was a United States Navy facility located at Naval Station Key West, Florida for the training of Service personnel in Sonar techniques and equipment, and Anti-submarine warfare.
