U.S. Marines with Task Force Koa Moana and the Papua New Guinea Defence Force, hike the historical Kokoda trail during Exercise Koa Moana, Papua New Guinea, June 22, 2016. In 1942 ammunition and supplies were trucked 45 kilometers from Port Moresby to Owers where they were repacked in Uberi, a major supply base just beyond the Goldie River. From Uberi only sure-footed native carriers were able to traverse the tortuous track ahead. (U.S. Marine Corps imagery by MCIPAC Combat Camera Lance Cpl. Jesus McCloud/ Released)
