Meet Bruno, a German Shepard who is one of nearly 3,000 dogs in the canine corps and a cherished military asset.
Bruno is trained as a patrol and detection dog. He's not unlike the four-legged commando who played a key role in hunting down Osama bin Laden inside a Pakistani compound. Dog handlers said it's no surprise that Navy Seals brought a dog with them on the stealth mission.
War dogs are trained to give early, silent warnings of danger - something man and machines often can't do.
The canines are trained to be the best of the best, but passing a test to become a military dog isn't easy.
Depending on the mission, the dogs could be outfitted with special gear, such as night-vision goggles (dubbed "doggles"), cooling vests, body armor that can withstand shrapnel and bullets and head mounted infrared cameras.
