Lethal weapons: Not all military dogs are trained to kill. According to the U.S. Air Force, a dog only enters advanced training after a basic obedience program is successfully completed. The focus of this more intensive training is "controlled aggressiveness" in which the dog is "taught to find a suspect or hostile person in a building or open area; to attack, without command, someone who is attacking its handler; to cease an attack upon command at any point after an attack command has been given..." Make no mistake, these animals can be lethal weapons: "The average German Shepherd's bite exerts between 400 and 700 pounds of pressure," according to the U.S. Air Force.
