Petty Officer 1st Class - Cryptologic Technician Rank Insignia Patch
A Petty Officer First Class is the third of the Navy's Petty Officer grades, and serves as a non-commissioned officer. A Petty Officer First Class serves both as a leader and as a technical expert, and all Petty Officers have a specified rating, or job. The exact title with which a petty officer is addressed depends on their specialty; a Petty Officer First Class serving as an Electronics Technician, for example, would have the full title of Electronics Technician First Class.
Petty Officer First Class is the 6th rank in the United States Navy with a grade of O-6, ranking above Petty Officer Second Class and directly below Chief Petty Officer.
Cryptologic technicians control the flow of messages and information and also conduct electronic warfare. Their work depends on their specific branch: CTAs or administration cryptologic technicians perform administrative and clerical duties that control access to classified material. CTIs or interpretive cryptologic technicians handle radiotelephone communications and foreign language translation. CTMs or maintenance cryptologic technicians maintain electronic and electromechanical equipment. CTNs or networking cryptologic technicians handle computer communication. CTRs or collection cryptologic technicians handle all Morse code communications and operate radio direction-finding equipment. Finally, CTTs or technical cryptologic technicians deal with electronic warfare. CTTs are the first line of defense against inbound threats and anti-ship missiles. They also collect, analyze, and provide electronic intelligence support to commands throughout the world.
