Chilean Air Force 1st Lt. Juan San Martin, medical health officer, looks at a Critical Care Air Transport Team’s medical supply kit on Dec. 7, at Camp Bramble on Joint Base San Antonio-Lackland, Texas. Each CCATT 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)
