Sergeant Jevin U. Rainey, a field radio operator serving with Headquarters Battalion, 1st Marine Division, pours water to dissolve salt during Exercise Desert Scimitar here, May 2, 2013. Rainey, a 27-year-old native of Schenectady, N.Y., added salt to the soil to increase its conductivity, strengthening the grounding for nearby antennas. Proper grounding increases the range and clarity of radio transmissions. (U.S. Marine Corps photo by Sgt. Jacob H. Harrer)
