Marines learn about the Joint Infantry Company Prototype during the Expeditionary Energy Concepts symposium at Marine Corps Base Camp Pendleton, California, May 3, 2016. The JIC-P is a wearable energy management system that uses multiple sources, including kinetic harvesting, to recharge batteries in radios and other equipment that cuts down the amount of weight each Marine has to carry and eliminates the need to frequently resupply forward units with fresh batteries. E2C features new technologies developed by outside companies to improve the reach and effectiveness of the Marine Corps. The three-day event also gives Marines who would work with the technology on a daily basis the opportunity to identify possible areas for improvement. - Marines learn about the Joint Infantry Company Prototype during the Expeditionary Energy Concepts symposium at Marine Corps Base Camp Pendleton, California, May 3, 2016.
