3/2 Marines Utilizing GREENS during ITX
  • Marines with 3rd Battalion, 2nd Marine Regiment (3/2) utilized the Ground Renewable Expeditionary Energy Network System (GREENS) at Camp Wilson, Twentynine Palms, CA during the Integrated Training Exercise (ITX).
  • For a week before receiving generators from the ITX issue point, 3/2 powered vital equipment utilizing GREENS.
  • Following receipt of generators, a Quonset hut providing relay switches lost power and the GREENS continued to provide power to that building for uninterrupted operations.


To change the way the Marine Corps employs energy and resources to increase combat effectiveness and reduce our need for logistics support.

Analyze, develop, and direct the Marine Corps’ energy strategy in order to optimize expeditionary capabilities across all warfighting functions.

Further, E2O’s role is to advise the Marine Requirements Oversight Council (MROC) on all energy and resource related requirements, acquisitions, and programmatic decisions. E2O serves as the Functional Advocate for Operational Energy.
