Marines with the 31st Marine Expeditionary Unit and Combat Logistics Battalion 31 pump purified water for citizens of Tinian, Commonwealth of the Northern Mariana Islands, Oct. 31, 2018. Marines with the 31st MEU and CLB-31 arrived on Tinian Oct. 29-30 in the wake of Super Typhoon Yutu as part of the U.S. Defense Support of Civil Authorities here. The Marines can purify more than 20-thousand gallons of sea water each day to meet the urgent needs of the people of Tinian. The Marines arrived at the request of CNMI officials and the U.S. Federal Emergency Management Agency to assist relief efforts in the wake of Yutu, the largest typhoon to ever hit a U.S. territory. The 31st MEU, the Marine Corps’ only continuously forward-deployed MEU, provides a flexible force ready to perform a wide-range of military operations across the Indo-Pacific region.
