U.S. Army Sgt. Michael McMillan, the 1st Space Company, Delta Detachment engagement control team leader, navigates his way through the woods as part of land navigation training at Misawa Air Base, Japan, Oct. 18, 2017. Having land navigation training in rough, dense terrain, both during dark and light hours, puts an added level of difficulty on Soldiers, affording them an opportunity to learn in a new environment while gaining essential survival skills.
