Always on watch: Airmen protect base Published Jan. 13, 2015 By Airman 1st Class Nicolo J. Daniello 92nd Air Refueling Wing Public Affairs FAIRCHILD AIR FORCE BASE, Wash. -- 92nd Security Forces Squadron installation entry controller Airmen perform their mission at the gate day, night, rain or shine to ensure only authorized individuals gain access onto the installation. They are Fairchild's first line of deterrence and professional first for all visitors. The gate guards use the Defense Biometric Identification System, a system that uses barcode technology, to screen individual identification cards to verify whether or not an individual is authorized access to the base. Using DBIDS they scan over 100,000 identification cards a day.
