The first time Changiz Lahidji joined a Special Forces unit, his loyalty was to Reza Pahlavi, the Shah of Iran. But he found himself guarding lavish parties in the middle of the desert, protecting the opulent ruler of Imperial Iran and his guests. It wasn't exactly the life of adventure that John Wayne movies led him to believe he could have.

He didn't stay in service to the Shah for very long. It seemed like a waste. So, he moved to California, working in family-owned gas stations until November, 1978. That's when he joined the Army and became an instrument of destruction — for the United States.

(Changiz Lahidji) The late 1970s were not a good time to be from the Middle East and living in the U.S., even if you're in the Army. He had to constantly endure racism from his fellow soldiers, even though they couldn't tell the difference between an Arab and a Persian. It didn't matter, Lahidji pressed on and finished Special Forces training. Less than a year later, he was wearing the coveted Green Beret and by December 1979, he was on his first mission. He was on his way back to Iran.

Lahidji wasn't about to wait for the military to get around to assigning him to help. He wrote a letter to President Jimmy Carter, offering his unique skills, knowledge of Tehran, and native Farsi to the task. He wanted to choose his A-Team and get to Iran as soon as possible. The U.S. military was happy to oblige. He wasn't going to lead an A-Team, but he had an Iranian passport and he went into Tehran ahead of Operation Eagle Claw in order to get advance knowledge of the situation on the ground and to rent a bus to drive hostages and operators out after they retook the embassy. After the disaster at Desert One, he was forced to smuggle himself out aboard a fishing boat.

Master Sgt. Changiz Lahidji, U.S. Army. (Changiz Lahidji) After Iran, he didn't have to worry about being accepted by his fellow Green Berets. He was one of them by then. He writes about all of his worldly adventures in some 33 countries in his memoir, Full Battle Rattle: My Story as the Longest-Serving Special Forces A-Team Soldier in American History. In it, you can read about him helping to bust drug rings in Spain, capture the mastermind behind the 1993 World Trade Center Bombing, and what it was like on the ground during the "Black Hawk Down" debacle in Mogadishu, Somalia. He was there for all of it.

But it wasn't the only time his Iranian background would come to the aid of U.S. forces. In 2003, some 24 years after the failure of Eagle Claw, Lahidji was in Tora Bora, dressed as a farmer and working for a U.S. private contractor. There, he would personally identify Osama bin Laden. When he went to the American embassy to report his finding, the U.S. seemed to take no action.
