CIMSEC – During a future conflict, the USMC may be operating multiple Expeditionary Advanced Bases (EABs) on dispersed islands across the Western Pacific. Within their respective island groups, the bases may reposition frequently to complicate enemy targeting. These EABs would either be established prior to the conflict while access was open, or they would be forcibly established with the joint support of naval assets fighting their way in. But naval support may not be accessible enough to provide steady logistical support to advance bases. This is an acutely challenging problem for EABs and demands innovation.
