Updated Status for H&S BN, HQMC, Henderson Hall, 17 September 2021

Face Mask Usage on Joint Base Myer Henderson Hall

According to the Centers for Disease Control and Prevention, both Washington D.C. and Arlington County are now "substantial" transmission areas for COVID-19 and the Delta variant. Face coverings are now required in all indoor settings on Myer, McNair and Henderson Hall - regardless of vaccination status. The mask mandate remains in place for all non-vaccinated individuals - both indoors and outdoors.

Our job is to defend our Nation's Capital and to be the face of the US Military. Vaccinating against COVID-19 is key to our continued success. Your efforts will make a difference in the fight against this disease. Be a part of the solution - get vaccinated.

The virus is still out there. As conditions change in the local area  we   must  continue to remain vigilant at work  and home.  Get vaccinated and  follow DOD, local and  CDC guidelines --- protect yourself, protect the team, protect the mission.

JBM·HH leadership continues to monitor the pandemic in the NCR and refine our conditions-based plan and continue to be focused on protecting the force, preserving readiness and mitigating the risk of transmission among personnel.


ID Card Center

The Henderson Hall ID Card Center is now located on the 3rd floor of the Marine Corps Exchange. The ID card center has new hours of 0900 to 1700 with the last customer being called in at 1630, by appointment only. In order to maintain appropriate safety measures there will be only two customers allowed in the office at one time.



Walk-in’s are welcomed for height and weight. Per MCO 6110.3W,  Ch 1, para 3.F.3 “The only authorized uniform for the weigh-in and BCE (if necessary) is the Marine Corps approved green-on-green T-shirt, shorts and socks. No other uniform or clothing garment is permitted.”

 Please bring your green on green with you.  NO EXCEPTIONS!

MARADMIN 442/21 reiterates the requirement for all military and civilian personnel with government computer and network access to complete FY2021 cyber awareness training. Please see the MARADMIN for more details and instructions on completing the training.

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.
