Assault amphibious vehicles, assigned to the 31st Marine Expeditionary Unit, transit toward Gold Beach for an amphibious assault during Talisman Sabre 2015 at Fog Bay, Australia, July 11, 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.
