English: Indian Ocean (Feb. 2, 2005) - A volunteer from the non-governmental organization "Project Hope" treats a simulated patient during a patient flow drill aboard the Military Sealift Command (MSC) hospital ship USNS Mercy (T-AH 19). The drill allowed military members and "Project Hope" medical personnel an opportunity to work with and learn from one another. Mercy has been forward deployed to assist in humanitarian aid efforts currently in progress. Mercy will serve as an enabling platform to assist humanitarian operations ashore in ways that host nations and international relief organization find useful. Mercy is deployed in support of Operation Unified Assistance, the multi-national humanitarian aid effort in the wake of the tsunami the hit Southeast Asia.
