U.S. Marines, assigned to the 31st Marine Expeditionary Unit, conduct small boat ops using Combat Rubber Raiding Craft (CRRC) from the amphibious transport dock ship USS Green Bay (LPD 20) during Talisman Sabre 2015 in the Indian Ocean, July 12, 2015. Talisman Sabre is a biennial exercise that provides an invaluable opportunity for nearly 30,000 U.S. and Australian Defence 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.
