The following is the April 2017 Government Accountability Office Report, Marine Corps Asia Pacific Realignment: DoD Should Resolve Capability Deficiencies and Infrastructure Risks and Revise Cost Estimates.
From the report:
The Department of Defense (DOD) has coordinated the relocation of Marines from Okinawa to other locations in the Asia-Pacific region through developing a synchronization plan and organizing working groups. However, DOD has not resolved selected identified capability deficiencies related to the relocation of Marine units; training needs in the region; the reduction in runway length at the Futenma Replacement Facility in Okinawa; and challenges for operating in Australia. DOD guidance indicates that mission requirements—which would include the capabilities needed to fulfill the mission—largely determine land and facility support requirements. If DOD does not resolve the selected identified capability deficiencies in its infrastructure plans, DOD may be unable to maintain its capabilities or face much higher costs to do so.
