Andreas Niemetschek, 90th SFS Delta Flight chief, during a nighttime training exercise Aug. 6, 2015, on F.E. Warren Air Force Base, Wyo. Every shift, day and night, 90th SFS defenders undergo at least one training exercise to keep their law enforcement skills sharp. Niemetschek simulated a gate runner and led Delta Flight on a car chase through the base before being surrounded and subdued. Niemetschek was not apprehended except for exercise purposes only.
