A U.S. Marine conducts high altitude – low opening jump from the back of an Air Force C-130H Hercules aircraft during jump week at Yokota Air Base, Japan, March 23, 2017. The training not only allowed the Marines to practice jumping, but it also allowed the Yokota aircrews to practice flight tactics and timed-package drops day and night.
