U.S. Army Reserve Sgt. Ryan Giegling inspect the filters in the filter separator tank during the Quartermaster Liquid Logistics Exercise (QLLEX) on Fort Huachuca, Ariz., June 10, 2015. According to Sgt. Vanessa Lauterwasser, clean rubber gloves must be worn while touching the filters to prevent any contamination in the fuel. Both Giegling and Lauterwasser are petroleum supply specialists assigned to the 383rd Quartermaster Company from St. Charles, Mo. The unit is tasked with running the “bag farm,” where fuel is stored during the QLLEX. (U.S. Army Reserve photo by Capt. Jill O’Dell, 364th Press Camp Headquarters)
