Brian Cheung, emergency nurse, 8th Forward Resuscitative and Surgical Detachment, 18th Medical Command, stitches a patient's head wound in the intensive care unit during the inaugural Papua New Guinea Trauma Rotation in Port Moresby General Hospital at Port Moresby, Papua New Guinea, Dec. 7, 2023. The Trauma Rotation follows the recent signing of the Defense Cooperation Agreement between the U.S. and Papua New Guinea; it is a first-of-its-kind engagement between the U.S. Army and Papua New Guinea, which mutually offers parties the a chance to exchange medical expertise and techniques in an austere environment.
