An Airman from the 386th Expeditionary Civil Engineer Squadron uses a Caterpillar 279D Multi-terrain Loader to clear debris after a simulated attack on a replicated runway during a rapid airfield damage recovery exercise at Ali Al Salem, Kuwait, Sept. 15, 2021. As the theater gateway of U.S. Central Command’s area of responsibility, maintaining a functional runway is key to delivering decisive combat power and support throughout the theater. RADR exercises ensure that ASAB is able to quickly repair runway damage and resume air operations. (U.S. Air Force photo by Tech. Sgt. Eric Summers Jr.)
