Joint U.S. service members and Royal Australia Air Force personnel pose for a photograph at the close of Talisman Sabre, July 17, 2015, at Joint Base Pearl Harbor-Hickam, Hawaii. Talisman Sabre is a biennial exercise that provides an invaluable opportunity for nearly 30,000 U.S. and Australian defense forces to conduct operations in a combined, joint and interagency environment that will increase both countries’ ability to plan and execute a full range of operations from combat missions to humanitarian assistance efforts.
