U.S. Army Reserve Pfc. An Chen, a water treatment specialist and Los Angeles, California native assigned to the 968th Quartermaster Company, wades through the Pacific Ocean to locate and inspect a dolphin strainer June 20, as part of the Quartermaster Liquid Logistics Exercise held at Camp Pendleton, California. The strainer is part of a Reverse Osmosis Water Purification Unit that removes sand and other ocean pollutants from the water so it can be purified for drinking. (U.S. Army Reserve photo by Sgt.
