Information Systems Technician (IT): Formerly known as Radioman (RM). Naval activities often involve people working at many different locations on land and at sea. ITs operate the radio communications systems that make such complex teamwork possible. ITs operate radio-telephones and radio-teletypes, prepare messages for international and domestic commercial telegraph, and send and receive messages via the Navy system, including satellites and antennas. ITs also are responsible for all computer systems, network administration (including LAN hardware), peripheral operations and systems modifications. Data Processing Technician (DP) rating merged into the RM field in 1997.

The IT rating is Robin's designated field and she is currently an ITSN (designated striker in pay grade E-3).
