Andrews Air Force Base according to the Banner Joint Base Andrews members participate in MARE exercise The largest Major Accident Response Exercise was held in the National Capital Regional April 26th and included participants from Joint Base Andrews in its exercises. MARE was known as "Exercise Sisyphus" according to the Banner, and was held in conjunction with the 79th Medical Wing from the Walter Reed Military Medical Center along with 11 other local hospitals. The exercise is designed to test all units currently on and off base at Joint Base Andrews and their emergency response level in the event of an aircraft accident at the annual Joint Service Open House and Air Show. Regan Simmons, Joint Task Force National Capital Region Medical training and exercise officer noted, "This exercise is the largest that we have ever done with Maryland's Region Five hospitals and the first time we've done this exercise with Andrews." The Prince George County Fire Department and the Prince George County Police Department also participated by providing essential communication links during the joint-partnership exercise. Simmons noted, "We were brought into this exercise to be the link between Andrews and Maryland's Region Five hospitals. We are the civilian/military representation for the civilian and military hospitals. Our role was to provide exercise role players with off-base hospitals. We're hoping that this will become an annual event, because this exercise supplied the Maryland's Region Five hospitals with mass casualty certifications, which they are required to do annually." Randolph Sena, 11th Wing chief of exercises and inspections noted that the scenario was designed to exercise the emergency response capabilities that Andrews will deploy during the upcoming 2012 Joint Service Open House and Air Show. Sena added, "I'm pleased that the exercise provided an opportunity for more than 15 federal, state and local agencies to exercise emergency-response capabilities. The interoperability between all of us to work together as one unified team demonstrates our capability to respond to any scenario."
