U.S. Air Force Tech. Sgt. Casey Carter, NCO in charge of survival, evasion, resistance and escape training with the 18th Operational Support Squadron, plays the role of a personnel recovery asset, simulating a nonconventional assisted recovery during a combat survival training course at Kadena Air Base, Japan, March 18, 2021. Isolated personnel are given a set of instructions on a place, time and action they’re supposed to take in order to get in contact with a PR asset. Real-world execution of this can be difficult due to limited information and uncontrolled events, so aircrew members are told that if two of the three criteria are met and they don’t have reservations about the scenario, they should proceed with caution and make contact with a PR asset.
