Why was a cat recruited to spy for the CIA during the Cold War?

What led President Franklin D. Roosevelt to approve the development of a "bat bomb" to be used against the Japanese in World War II?

And how were dolphins trained to seek out enemy divers in Vietnam?

Find out all this and more in this riveting episode of "War Stories with Oliver North." From antiquity to present day, you’ll learn how these unsung heroes have braved enemy fire to keep our troops safe.

You’ll hear from a 103-year-old World War I cavalryman and a Vietnam veteran who wouldn’t be alive if it weren’t for his war dog, Kelly.

We also take you inside behavioral training of animals that, at first glance, don’t appear to be trainable.

And go along for a day in the life of today’s war dogs at the the Department of Defense Military Working Dog School at Lackland Air Force Base. You’ll see how our four-legged warriors are being trained in drug and explosive detection.
