Expeditionary Energy Concepts (E2C) (formerly known as ExFOB) page. Once a year, the Marine Corps invites industry to the E2C technology demonstration to demonstrate commercial technologies with potential to address current Marine Corps energy, water, and waste capability gaps.

The 2016 Expeditionary Energy Concepts (E2C) technology demonstration (formerly known as ExFOB) was held
3-5 May 2016 at Marine Corps Base Camp Pendleton, California.

E2C 2016 focused on four technology areas:
1. Squad-sized Small Unit Water Purification
2. Energy Storage Technology for Mobile Electric Micro-grid Application
3. Energy Scavenging to Support Distributed Operations
4. Optimization of Shock Trauma Platoon/Forward Resuscitative Surgical System

To learn more, view the E2C 2016 fact sheet.

Created by the Commandant in 2009, the United States Marine Corps' Expeditionary Energy Concepts (E2C) technology demonstration (formerly known as Experimental Forward Operating Base (ExFOB)) brings together stakeholders from across the Marine Corps requirements, acquisition, and technology development communities in a dynamic process to quickly evaluate and deploy technologies that reduce our need for "liquid logistics" today, and to establish requirements for tomorrow. E2C guides the development of new requirements documents and informs Marine Corps investment decisions, taking new capabilities "from concept to combat".

Once a year, industry is invited to E2C (formerly ExFOB) to demonstrate off-the-shelf technologies with potential to address current material and non-material capability gaps identified in the Marine Corps E2W2 ICD. Promising technologies are then put into the hands of Marines for extended user evaluation under combat and training conditions. User evaluation results inform requirements development and ultimately lead to procurement and fielding of systems that close these gaps, resulting in a more combat-effective fighting force. To learn more, visit the E2C Process page.

Once fielded, energy and water technologies first demonstrated at E2C / ExFOB will increase the operational reach of the force. Specific capability gains expected from these systems include:

  • Power patrol bases entirely on renewable energy

  • Conduct extended foot patrols with limited or no fuel or battery resupply

  • Lighten the carried load of batteries and water for a 96-hour patrol from ~65 lb to ~7 lb

  • Reduce the need to carry multiple types of batteries

  • Reduce generator runtime by up to 80 percent and generator fuel use by up to 50 percent

  • Increase fuel efficiency of the Medium Tactical Vehicle Replacement (MTVR) by 25 percent or more

  • Reduce vehicle fuel use while idling by 30 percent

Five energy efficient systems first introduced by industry at past E2C technology demonstrations are currently Program of Record and available to the fleet today:



  • Radiant Barrier

  • LED Lights


See the E2O Fleet page for more information about these E2C success story systems.

E2C Team

In July 2010, India Company, 3rd Battalion, 5th Marine Regiment trained on and deployed to Afghanistan with a suite of renewable energy technologies demonstrated at the first ExFOB. With these systems in place, India 3/5 operated two patrol bases entirely on renewable energy, reduced fuel consumption at a third base by 90%, and executed a three-week foot patrol without battery resupply, lightening their carried load by 700 pounds.
