SAN DIEGO (April 14, 2022) Dan Boehm, an instructor from the United States Army Medical Research Institute of Chemical Defense (USAMRICD) (center left), instructs Sailors assigned to the Military Sealift Command hospital ship USNS Mercy (T-AH 19) on procedures for a training exercise aboard the ship’s flight deck April 14. The drill focuses on chemical warfare response. Mercy can steam to assist anywhere to provide relief as a symbol of Navy Medicine’s abilities around the world, and must be in a five-day-activation status in order to support missions over the horizon, and be ready, reliable and resilient to support mission commanders.
