Marine Corps installations are integral hubs of their local communities and strive to balance good stewardship of the environment with meeting the requirements to train Marines and sailors, all while remaining good neighbors. The E&MS branch advances these goals by integrating communications, outreach, and engagement in support of encroachment management, legislative engagement, mission compatibility, and liaison with installation communities, elected officials, and mission partners at all echelons.

The Marine Corps strives to foster positive and proactive relationships with our installation neighbors, as well as other local and national communities by providing effective community outreach and education. The Community Plans & Liaison Officer (CPLO) is the Commander's representative to neighboring communities, elected officials, and other government agencies. CPLOs foster and maintain relationships with the community and government leaders to promote mission sustainment, and share matters pertaining to the current and emerging missions of an installations to alleviate pressure on current and emerging mission and training requirements.

Marine Corps Mission Sustainment Program
The Marine Corps Mission Sustainment Program is a key program for maintaining installation readiness to support the Marine Corps Operating Forces. As communities and local economies grow, the Marine Corps seeks to promote compatible land uses to prevent the loss of training days and workarounds that would reduce training realism and effectiveness. The Mission Sustainment Program relies on continuous stakeholder engagement, encroachment partnering, and various engagement and planning tools to identify and address encroachment concerns early in the development process and create win-win-win solutions for the Marine Corps, communities, and the environment. The mission sustainment program is implemented at the regional and local level by CPLOs.
