Drake Masterson, with 3rd Battalion (Airborne), 509th Infantry, 4th Brigade Combat Team (Airborne), 25th Infantry Division apply camouflage in preparation for a mass-tactical airborne operation during Exercise Talisman Sabre 15 at Shoalwater Bay Training Area, Australia, July 8, 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.
