The Bureau of Alcohol, Tobacco, Firearms and Explosives' National Canine Division teaches working dogs the different odors of homemade explosives during the three-day National Odor Recognition Training and Testing on Naval Weapons Station Fallbrook, Calif., May 23, 2018. The purpose of NORT is to standardize training for explosive detection dogs by exposing them to a series of components used in homemade explosives they may be unfamiliar with so they can protect their communities from explosive threats.
