 With organizational changes to Marine Corps' reconnaissance units in 2006, all the MEU's Special Operations Capable (SOC) designations were removed.The 31st MEU then became titled as a Maritime Contingency Force, although it remains capable of conducting the same wide variety of specialized missions on both sea and land.In February 2006, the 31st MEU was sent to the Philippines to provide relief assistance during the mudslides in southern Leyte.
