At the age of 15 as a Navajo Native American, Peter MacDonald enlisted in the US Marines simply because he admired the official uniform.  Shortly after boot camp, he was recruited into a secret military program that would rely on a language that has no written form for what would later be known as a Navajo Code Talker.

The code talkers were pivotal during the Battle of Iwo Jima, a 6 week intense battle that resulted in 25,000 casualties on both sides.    From a group of 450 Navajo Native Americans, MacDonald is only one of five surviving Navajo Code Talkers and he shares his life experience with Anthony Arno.  After the war, MacDonald was sworn to a code of secrecy for the next 23 years while working as a Project Engineer for Howard Hughes on The Polaris Missile Project.  MacDonald also served as a Chairman of the Navajo Nation for four terms.
