Farah, 341st Security Forces Squadron military working dog, indicates the direction of a hidden bomb during detection training at Malmstrom Air Force Base, Mont., Jan. 24, 2023. Bomb detection dogs can smell chemicals ranging from ammonium nitrate to potassium chlorate. K-9 olfactory abilities are 10,000 times greater than those of a human, which makes them extremely reliable detection tools for the military. (U.S. Air Force photo by Airman 1st Class Mary Bowers)
