TMs perform organizational and intermediate level
maintenance on underwater ordnance such as torpedoes
and antisubmarine rockets. They operate and maintain
test equipment, launching and firing systems, and
storage facilities associated with underwater ordnance.
They also prepare underwater ordnance for launching
and conduct postfiring routines and securing and
evaluation procedures.
OCCUPATIONAL FIELD 10 (SENSOR
OPERATIONS).— This occupational field includes
the Electronics Warfare Technician (EW), Ocean
Systems Technician (OT), and Sonar Technician (ST)
ratings.
Electronics Warfare Technician.—The insignia
for the Electronics Warfare Technician (EW) rating is a
helium atom slashed by a lightning bolt.
EWs operate and perform organizational and
intermediate level maintenance on electronic warfare
systems and associated supporting equipment. They
extract, interpret and apply data from intelligence
publications, reports, and other documentation. Senior
EWs train and supervise personnel in EW assignments
and supervise the preparation of electronic warfare
reports.
Ocean Systems Technician.— The insignia for the
Ocean Systems Technician (OT) rating is a trident
crossed by waves.
OTs operate analysis, localization, correlation,
resource allocation, communications, and display
equipment associated with the Integrated Undersea
Surveillance System (IUSS) for the analysis,
evaluation, and interpretation of acoustic data for
operational use. They evaluate equipment operation,
locate and analyze equipment casualties, and make
repairs and adjustments. They align, maintain,
supervise the maintenance of IUSS equipment.
and
OTs are divided into two categories: (1) Ocean
Systems Technicians (Analyst) (OTAs) and (2) Ocean
Systems Technicians (Maintainer) (OTMs). Some of
their specific responsibilities are reflected in the next
paragraph.
The OTAs operate the analysis, localization,
correlation, resource allocation, communication, and
display equipment associated with the IUSS for the
analysis, evaluation, and interpretation of acoustic data
for operational use.
On the other hand, the OTMs
perform preventive and corrective maintenance at the
organizational level on IUSS digital and analog
equipment.
Sonar Technician.—The insignia for the Sonar
Technician (ST) rating is the symbol of earphones
pierced by an arrow.
STs are divided into two categories: (1) Sonar
Technicians, Surface (STGs) and (2) Sonar
Technicians, Submarine (STSs). Some of their specific
responsibilities are listed in the next two paragraphs.
The STGs operate (manipulate, control, evaluate,
and interpret data) surface sonar and oceanographic
equipment, surface ship underwater fire control
equipment, and associated equipment for the solution
of antisubmarine warfare problems. They also perform
organizational and intermediate maintenance on
surface sonar and allied equipment.
The STSs operate (manipulate, control, evaluate,
and interpret data) submarine sonar and oceanographic
equipment and submarine auxiliary sonar. They
coordinate submarine sonar and underwater fire control
interface and perform organizational and intermediate
maintenance on submarine and allied equipment.
OCCUPATIONAL FIELD 12 (DATA
SYSTEMS).— This occupational field includes the
Data Processing Technician (DP) and Data Systems
Technician (DS) ratings.
Data Processing Technician.— The insignia for
the Data Processing Technician (DP) rating is the
symbol of a quill resting on a gear.
