  In accordance with Secretary of Defense guidance and effort to reduce the risk of exposure and community spread of the novel coronavirus disease (COVID-19) outbreak, the Consolidated Administration Center (CONAD) will be limiting close contact with supported personnel and conducting the majority of administrative tasks via Marine Online (MOL) Electronic Personnel Administrative Requests (EPAR). All members requiring routine support will be directed to utilize this online system to process their requests. Members reporting for duty on PCS or PCA orders and members issued PCS or PCA orders that require signatures to accept are still permitted and required to physically report to CONAD as these actions need to be completed in person with an administrative specialist. Beginning February 16, 2021, the Consolidated Administration Center (CONAD) will be transitioning to adjusted hours by opening at 0730, with the last customer being serviced at 1600, Monday through Wednesday, and Friday.  Thursday, the CONAD will be open from 0730-1200.


On January 1, 2021 NCR Members COLA changes to their payments. CONUS COLA monthly payments range from $32 to $60 month for members with dependents and $22 to $46 monthly for those without dependents. Washington, DC (us) and Warren, VA fall under this change so do not be surprised by this change in your direct deposits. Please Check out DoD's CONUS COLA calculator for details.


This advisory is to reiterate the policy concerning permissive temporary additional duty (PTAD) for the Reserve component.  Per the leave and liberty manual, Reserve Marines who have been mobilized on active duty orders DO NOT rate any type of PTAD.  Active Duty and Active Reserve component Marines are the only Marines entitled to PTAD.

Assistance: For questions or concerns, please contact the CONAD at (703) 614-7171 or the Customer Service/Pay section SNCO, GySgt Kelly at


Negative COVID-19 Test Results Required Within 72 Hours of Departure Date for International Flights

Marines must have COVID-19 negative test results in hand prior to arriving at Aerial Port of Embarkation (APOE’s) such as Seattle International Airport (SEA) and Baltimore Washington International Airport (BWI) when traveling on AMC Patriot Express flights.  Passengers may be denied travel without negative test results in hand.  There is testing available on-site as a last resort, but it is limited, so again there is a chance some travelers may be denied travel if everyone isn’t tested by the flight close-out time. 

During the Tuesday, 23 February Joint Staff J4 COVID-19 teleconference, Air Mobility Command Headquarters briefed that the Services must do a better job of getting the word out to travelers advising them to have a copy of the COVID-19 negative test results in hand.  The percentage of personnel with COVID-19 negative test results within 72 hours of the departure date for international flights departing from CONUS APOEs should be over 80%.  For the past two weeks, it averaged just 49%.  Therefore, the APOEs had to test over 1,200 personnel because they did not have test results and the APOEs cannot afford to keep up that tempo with the amount of test kits they have on hand. 

All travelers and their dependents heading to Baltimore or Seattle APOEs must have those test results with them as a hard copy only and they must keep that copy on them until they arrive at their OCONUS destination.
If you have any questions, please contact 703-614-7191,
