Electrician’s Mate (EM) rating is represented as a globe
of the world.
EMs operate and perform organizational and
intermediate maintenance on power and lighting
circuits, electrical fixtures, film projectors, motors,
generators, voltage and frequency regulators,

electrical equipment.
EMs test for short circuits,
grounds, and other casualties. They also rebuild
electrical equipment, including solid state circuitry
elements, in an electrical shop. They stand generator,
switchboard, control equipment,
equipment watches.
Engineman.— The insignia for
(EN) rating is represented as a gear.
and electrical
the Engineman
ENs operate, repair, and perform organizational and
intermediate maintenance on internal-combustion
engines, main propulsion machinery, refrigeration and
air-conditioning equipment and systems, gas turbine
engines, and assigned auxiliary equipment. They also
stand watches on auxiliary boilers.
Gas Turbine Systems Technician.— The insignia
for the Gas Turbine Systems Technician (GS) rating is
a cross section of a turbine.
GSs operate, repair, and perform organizational and
intermediate maintenance on gas turbine engines and
main propulsion machinery (including gears, shafting,
and controllable pitch propellers). They also perform
maintenance on assigned auxiliary equipment,
propulsion control systems, assigned electrical and
electronic circuitry (up to the printed circuit), and alarm
warning circuitry.
GSs are divided into two categories: (1) Gas
Turbine Systems Technician (Electrical) (GSE) and (2)
Gas Turbine Systems Technician (Mechanical) (GSM).
Some of their specific responsibilities are listed in the
next two paragraphs.
GSEs operate, repair, and perform organizational
and intermediate maintenance on the electrical
components of gas turbine engines. They also operate,
repair, and perform maintenance on main propulsion
machinery, auxiliary equipment, propulsion control
systems, assigned electrical and electronic circuitry (up
to the printed circuit), and alarm and warning circuitry.
GSMs operate, repair, and perform organizational
and intermediate maintenance on the mechanical
components of gas turbine engines. They also operate,
repair, and perform maintenance on main propulsion
machinery (including gears, shafts, and controllable
pitch propellers), assigned auxiliary equipment, and
propulsion control systems.
Interior Communications Electrician.— The
insignia for the Interior Communications Electrician
(IC) rating is a telephone over a globe.
