Combat Leader Course TITAN missile silo rescue
U.S. Airmen, training with the 68th Rescue Squadron, monitor their teammate’s oxygen level as he conducts rescue operations in a simulated low-oxygen environment during a Combat Leader Course training exercise at the Titan Missile Museum in Green Valley, Ariz., Aug. 21, 2023. The simulated low-oxygen environment required the student who descended to the lowest level to breathe from an oxygen tank which effectively simulated a possible real-world scenario.
