Army 91D MOS: Tactical Power Generation Specialist

In today’s post, I’m going to educate you about the Army 91D MOS, the Tactical Power Generation Specialist.

Here’s a brief description of the MOS, from two different trusted websites.

The Tactical Power Generation Specialist supervises operation and performs field level maintenance functions, including overhaul, but not rebuild of power generation equipment, internal combustion engines and associated equipment up through 200KW (except for turbine engine driven generators). ~ Cool.OSD.mil

And…

91D involves tactical power generation. Power generation is the set of mechanisms and processes necessary to move electrical energy from its generation point to a point where it can accommodate the power demands of an electrical load. This MOS encompasses all aspects of tactical power generation, including development, production, delivery, storage, and use. Additionally, these services are required to provide guidance for units on tactical power generation.
This MOS provides opportunities for individuals with experience in all areas of Tactical Power Generation to develop technical skills to meet the growing demand for tactical power generators by developing strategies that are cost-effective and provide optimum performance. This requires planning that addresses potential growth/expansion needs over the next 20 years. ~ Hood MWR
