Former Korea Augmentation to the U.S. Army (KATUSA) soldiers learn about weapon systems for a mobilization exercise at Camp Humphreys, South Korea, Aug 19, 2025. The MOBEX is to provide former KATUSAs, who are now in an inactive reserve status, their mandatory annual training. For a week, the KATUSAs go through basic marksmanship training, first aid, military policy and chemical, biological, radiological and nuclear threat training. The training is conducted by 2nd Infantry Division, ROK-US Combined Division Soldiers. The event is part of Ulchi Freedom Shield 25, an annual exercise designed to strengthen the combined defense posture and Republic of Korea-U.S. alliance response capabilities based on scenarios that reflect diverse threats within the security environment. The rigorous training will ensure the alliance is ready to defend the Republic of Korea and promote security in Northeast Asia. (U.S. Army photo by Spc. Rylen Ciota)
