A U.S. Marine from Detachment 18, Marine Medium Tiltrotor Squadron 262, 31st Marine Expeditionary Unit, controls the hose connection on the collapsible fuel tank during joint training at Kadena Air Base, Japan, March 11, 2021. Thirteen Marines participated in the joint training, some in a shadowing capacity to observe and learn. Hands-on training like this teaches service members to solve real-world problems that could occur in the field. (U.S. Air Force photo by Airman 1st Class Anna Nolte)
