John Dailey remembers the day he decided to become a U.S. Marine. He was a young boy at a U.S. bicentennial parade in 1976. When he saw the Marine in dress uniform, he was hooked. Eleven years later, fresh out of high school, Dailey enlisted in the Marines. Soon he was guarding the U.S. embassy in Hungary while the Iron Curtain was teetering and later held the same role in Argentina. He also passed sniper and reconnaissance training. But in his first 14 years of service, he never saw combat. That is until 9/11 happened while he was half a world away.

In this edition of "Veterans Chronicles," Dailey tells us how he learned of the devastating attacks on our nation, how he was among the first Marines in Afghanistan, and the judgment and decisiveness he exercised in his first combat duties there.

Then Dailey explains how he helped to stand up a U.S. Marine Corps recon unit and get it ready for service in Iraq. He also takes us along for the ride as he recounts what it took to find and capture high value targets in Iraq and how he put his sniper skills to use against allies of radical cleric Moqtada al-Sadr.

Finally, Dailey details why the special operations unit was disbanded after he returned to the U.S. and how he soon worked to help establish the the Marines' own special operations command (MARSOC) and the current generation of Marine Raiders.

He is also the author of "Tough Rugged Bastards: A Memoir of a Life in Marine Special Operations."
