MCIEAST standardizes the quality of support and service Marines receive on the various bases and stations. As the parent command for these installations, MCIEAST takes the best practices from its subordinate commands and apply them to all the other commands. It also strives to better supports the Corps’ warfighting requirements by returning more Marines to the operational forces. The restructuring of base and station management enables MCIEAST to support deploying units more efficiently and with fewer Marines. By standardizing support practices, MCIEAST eliminates manpower redundancies throughout the bases and stations. Finally, MCIEAST better supports the Corps’ warfighting requirements by saving money. By managing bases and stations more efficiently through the basic warfighting precept of centralized command and decentralized execution, MCIEAST will have oversight of regional funds and resources and allocate them just where they are needed. As a regional command, MCIEAST seeks to eliminate resource redundancies throughout the bases and stations and ensures that funds are utilized effectively while continuing to provide thorough support to the operational units.
