They operate and perform organizational and intermediate maintenance on alarm, warning, and indicator systems; interior communications; and ship's control, entertainment, and navigation systems.[1] IC is one of the most versatile ratings in the U.S. Navy with equipment all the way forward, all the way aft, all the way up the mast and on the bottom of the ship. Members of this rating are commonly referred to as "IC-men" by Navy personnel.

These communication systems include public address systems, interior telephone systems, alarm systems, engine telegraphs to communicate orders for changes in engine speed from the bridge (ship's command station) to the engine room, certain kinds of ship control and equipment monitoring devices, the ship's gyrocompass, the rudder position indicator, audio-visual equipment for the ship's TV entertainment systems, advanced navigation and various other equipment.

Working environment[edit]

People in the IC rating work in many different situations, at sea and ashore. While most of their work is performed indoors, it may be in a clean or dirty environment or a shop-like nature, and it may be in any kind of climate or temperature. ICs usually work closely with others. Most systems ICs work on is of the modern solid state electronic type, making the rating a very technical profession. All ICs require a secret security clearance.
