U.S. Air Force Capt. Jane Marlow, 37th Airlift Squadron pilot, reads the instructions on how to properly use a signaling mirror during Survival, Evasion, Rescue, and Escape training in Bolovari, Romania, Aug. 24, 2018. The mirror allows the user to accurately reflect light from the sun into whichever direction they need by utilizing the hole inlaid with mesh. The SERE training was part of Carpathian Summer 2018, a bilateral training exercise designed to enhance interoperability and readiness of forces by conducting combined air operations with the Romanian air force.
