Operation Specialists (OS) function as plotters, radio-telephone and Command and Control sound-powered telephone talkers and maintain Combat Information Center (CIC) displays of strategic and tactical information. They operate surveillance and altitude radars Identification Friend or Foe (IFF), and associated equipment. They also serve as Air Traffic Controllers for helicopters and fixed-wing supersonic jet aircraft. OS Sailors serve as watch supervisors and section leaders; interpret and evaluate presentations and tactical situations and make recommendations to supervisors during watch conditions. They apply a thorough knowledge of doctrine and procedures applicable to CIC operations contained in U. S. Navy Instructions and Allied or U.S. Navy Publications and procedures necessary for radar navigation contained in Naval Oceanographic Office publications. OSs provide to the command technical information and assistance related to Anti-Surface Warfare, Anti-Air Warfare, Anti-Submarine Warfare, Amphibious Warfare, Mine Warfare, Naval Gunfire Support, and search and rescue operations, and other matters pertaining to the Operations Specialist's area.
Operations Specialists usually work in a clean, air-conditioned electronic equipment space or computer room, and frequently perform their work as part of a team, but may work on individual projects. Their work is mostly mental analysis and problem solving. USN OSs are stationed primarily aboard USN deploying ships, FTS OSs are stationed aboard Naval Reserve Force (NRF) ships that deploy or conduct local operations.
