As part of the landmark inter-Korean Comprehensive Military Agreement signed by North and South Korean leaders in 2018, Arrowhead Hill was selected as the site for a joint remains recovery mission. Also known as Hill 281, the site was one of the fiercest battles during the Korean War, where about 300 American and French troops are believed to be buried. The mission required extensive demining to enable the remains recovery. As part of UNC, Australia actively facilitated the Arrowhead Hill mission by providing a support team for both the demining and remains recovery activities at the site. When operations ended for the year, UNC had supported the recovery of 1,742 bone fragments suspected to be associated with 198 individuals.
