Which Marine expeditionary force responded to the tsunami disaster in 2004?

The Marine expeditionary force that responded to the tsunami disaster in 2004 was the III Marine Expeditionary Force (III MEF). Following the catastrophic tsunami that struck Southeast Asia on December 26, 2004, III MEF, based in Okinawa, Japan, was deployed to provide humanitarian assistance and disaster relief to the affected regions, particularly in Indonesia and Thailand.

This response highlighted the rapid deployment capability of the Marine Corps and the importance of the III MEF in Pacific operations. Its proximity to the disaster area allowed for a swift response, which included the provision of food, water, medical aid, and logistical support to the affected populations, demonstrating the versatility and effectiveness of Marine forces in humanitarian missions.
