2015 Emerald Coast K-9 Clash
                Military working dogs and their handlers ruck through a creek, Sept. 4, 2015, at Hurlburt Field, Fla. The 2015 Emerald Coast K-9 Clash began at dawn on Friday with the “Iron Dog” endurance event, which began with a 6-mile ruck march in which the dog handlers carried a heavy ruck sack on their backs. That challenge was followed by a 1.5-mile run, culminating with a 1-mile “buddy carry.” (U.S. Air Force photo by Senior Airman Ryan Conroy/Released)
