This Joint Operating Procedure prescribes policies, assigns responsibilities, and mandates procedures necessary for management and standardization of Mobile Electric Power Generating Sources (and systems) utilized by all the Military Services and the Defense Logistics Agency worldwide. It addresses administrative functions in the areas of contracts and production, program management, logistics support, and configuration/data management. This regulation applies to the entire Department of Defense Standard Family of MEPGS and approved deviations from the Standard Family, but does not apply to fixed electric power or nuclear-fueled electric power generating sources (see DODD 4120.11, para C for complete definitions). This JOP provides specific and detailed guidelines for the proper management operations required of the Project Manager-Mobile Electric Power. These management operations are necessary to link the major functions of the PM-MEP to elements of DOD components involved with MEPGS.
