Jae Hyun Kweon of Incheon, South Korea, adjust her Multiple Integrated Laser Engagement System, on Aug. 11, 2019 during the Combat Support Tactical Exercise at Fort McCoy, Wis. The MILES allows troops to tell if they have been “hit” by enemy fire during training. Both Soldiers are operating room specialists with the 856th Combat Support Hospital. The 207th Regional Support Group, which processed units participating in the CSTX, projected almost 4,000 joint service members would attend its August phase, including Army, Navy, Air Force and Marine personnel.
