Most OS positions are located at sea aboard ships, which means much time will be spent away from home. However with specialized training, some operations specialists function as combat air controllers and work aboard aircraft. The job usually consists of working in the combat information centers or combat direction centers on a ship's bridge. Typically they operate radar, navigation and communications equipment, along with detecting and tracking other ships, aircraft and missiles. When underway, the job can be stressful and intense requiring quick thinking, the ability to make calculations on the fly, and to quickly determine the relevance to the mission of the massive amounts of information coming in.
