 Marines fight with rifles and grenades, but Marine working dogs fight the unseen enemy with their noses. Books, an explosive detecting military working dog, has been in the Marine Corps for seven years. During Marine Week Cleveland, spectators like this Marine mom learned how these dogs worked to keep Marines like her son safe. Yes, I am so thankful to their service as well. They mean so much just as the men. They are Marines as well. Books's nose is five to ten times more powerful than his handlers, giving him the upper hand against improvised explosive devices. Marine working dogs are always promoted to the rank above their handler, so when the dog makes a call, the handler listens. Books has proven himself by locating 12 IEDs throughout his career and in the process saving Marine lives. They're as loyal as can be, which is all the qualities you want out of the Marine to your left or right, but with the dogs, they're just as courageous, loyal, everything. With over 640 working dogs in the Corps, Marines can rest much easier knowing their lives are in good pause. From Cleveland, I'm Lance Corporal, John Tucker.
