Staff Sgt. Jeremiah Williams, 50th Security Forces Squadron investigator, discovers contraband during a vehicle search training scenario at the 50th SFS training facility at Schriever Air Force Base, Colorado, March 16, 2019. The training flight uses a “crawl, walk, run” method for training sessions, a philosophical and practical approach to training used not only in the field, but classrooms as well.
