Dogs have been working in combat roles alongside American soldiers for more than 100 years. In fact, they have been alongside soldiers since antiquity. But only in 1942, were dogs officially inducted into the U.S. Army.
Dogs have played a central part in more recent actions in Iraq and Afghanistan where about 2,700 dogs were serving worldwide, according to the U.S. Defense Department. It was the largest deployment of canines in the world.
These “war dogs” are used on patrols, in drug and explosives detection, and on specialized missions, like the Navy SEAL raid that took down Osama bin Laden.
