Gregory Curl, left, aircraft handling officer aboard the Nimitz-class aircraft carrier USS George Washington (CVN 73), explains flight deck operations to guests from Australia and New Zealand during a distinguished visitor embark as part of Talisman Sabre 2015. 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.
