The United States Marine Corps is too dependent on fossil fuel, which leaves logistics fuel support and supply lines vulnerable to attack, potentially degrading Marine Corps capabilities and ultimately putting Marines at risk. A need exists to identify doctrine, organization, training, materiel, leadership and education, personnel, and facilities DOTMLPF changes that provide a positive impact on energy efficiency while maintaining or improving operational effectiveness, essentially improving operational reach. Using the systems engineering process, key capabilities were identified from the Expeditionary Energy Office E2O stakeholders and used to develop a methodology to assess potential improvements to operational reach in the context of a Marine Expeditionary Unit MEU operation. At the heart of the methodology was a discrete event model developed to simulate the conditions of a close air support CAS operation and ground combat support GCS operation. Using a specific ship-to-shore vignette, factors were identified and a design of experiments DOE analysis was conducted to assess changes to doctrine, aircraft materiel solution, and environmental conditions on operational reach. This report a demonstrates the methodology developed, b identifies the effects of the factors on extending the operational reach of a CAS and GCS operation, and c recommends future efforts to continue research.
