Operations Specialist (United States Navy)
Operations Specialist (abbreviated as OS) is a United States Navy and United States Coast Guard occupational rating. It is a sea duty-intensive rating in the Navy while most of Coast Guard OS's are at ashore Command Centers. Brief history The rating started from the radarman (RD) rating. In the U.S. Coast Guard the Operations specialist rate was formed by combining the radarman (RD) and telecommunications specialist rate (TC). When the radarman rating was split up into OS, electronics technician (ET), and electronic warfare technician (EW) ratings, the original RD rating badge continued to be used by the operations specialist. It symbolizes the radar scope (circle portion of symbol) oscilloscope radar (O-scope) used to determine a target's range from the radar antenna (the two spikes in the line drawn across the scope), and the arrow represents the ability to detect the azimuth or direction of the target.

Naval Training Center
A navy, naval force, military maritime fleet, war navy, or maritime force is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is projection of force into areas beyond a country's shores (for example, to protect sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of a navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles.

Radar
Radar is a system that uses radio waves to determine the distance ('' ranging''), direction ( azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain. The term ''RADAR'' was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging". The term ''radar'' has since entered English and other languages as an anacronym, a common noun, losing all capitalization. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwave domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving ...
