Capt. Jennifer Swann, the 379th Expeditionary Medical Group Blood Transshipment Center officer in charge, scoops out dry ice from a freezer inside the Blood Transshipment Center at Al Udeid Air Base, Qatar, Jan. 13, 2016. Dry ice is needed to keep blood cool throughout the shipping process. The facility can house more than 4,000 pounds of dry ice. The center shipped nearly 23,000 units of blood to more than 30 forward operating locations in the U.S. Central Command area of responsibility in 2015. (U.S. Air Force photo/Tech. Sgt. James Hodgman)
