Who We Are

E2O works closely with the combat and technology development communities and serves as the proponent for Expeditionary Energy in the force development process. Additionally, E2O is tasked with advising the Marine Requirements Oversight Council on all energy and resource-related requirements, acquisitions, and programmatic decisions. And, in accordance with the National Defense Authorization Act for Fiscal Year 2009, the Secretary of the Navy assigned the E2O responsibilities as the Marine Corps Senior Official for Operational Energy.

E2O seeks to extend the operational reach of the 2024 Marine Expeditionary Brigade/Force (MEB/MEF) through energy risk analysis, technology development, and training to shape future concepts and capabilities.

Historical Context and Guidance:

• In 2009, the Commandant of the Marine Corps prioritized energy, emphasizing its role in increasing combat effectiveness through efficient battlefield energy use.

• In 2011, the Commandant issued the Expeditionary Energy Strategy and Implementation Plan, focusing on ethos, efficiency, and renewable energy from “Bases to Battlefield.” That same year, the Assistant Commandant released the Expeditionary Energy, Water, and Waste Initial Capabilities Document (E2W2 ICD), identifying 152 capability gaps (material and non-material) to meet the Commandant’s 2025 goals.

• These documents, alongside the 2012 Marine Corps Science and Technology Strategic Plan, provide a framework for investment in expeditionary energy modernization.

Since 2009, over $352 million has been invested, yielding significant reductions in weight and fuel transport, enhancing military capability. In 2012, the Commandant identified Expeditionary Energy as one of six pillars of modernization, critical for maintaining operational readiness for current and future conflicts.
