More than 55 Air Force District of Washington members trained at the Memorial Tunnel in Gallagher W.Va. for a two-week exercise March 19-30, code named Black Flag. The exercise was hosted by the Center for National Response, which is managed by the West Virginia National Guard as an element of the Joint Interagency Training and Education Center. The training site is ideal for consequence and crisis-management emergency response training. It provides a realistic environment where emergency response teams can readily practice techniques and is an excellent base for training on HAZMAT response, simulated agent testing, illicit chemical, biological, or drug laboratory entry and containment, EOD operations, underground search and rescue, counter terrorist tactics, and hostage rescue.
