Chilean air force Capt. Vivian Leiva, medical health officer, looks through a bag of medical supplies used on Critical Care Air Transport missions on Dec. 7, at Camp Bramble on Joint Base San Antonio-Lackland, Texas. Each CCAT Team carries roughly 560 pounds of gear, enough to continue the level of acute care for three critically ill patients up to 24 hours. (U.S. Air Force photo by Kiley Dougherty)
