Video: The Best War Equipment

As I travel around the country profiling American heroes, I continue to be astonished at the pride, dedication and selfless tenacity of the men and women who make up our military.

U.S. Special Forces soldier Don Hollenbaugh not only personifies those qualities, he proves that it's never too late to be an American hero.

At 40 years old, he has served nearly two decades in the military without seeing combat. Now, Hollenbaugh found himself on a rooftop in Fallujah, Iraq, underfire by insurgents.

When the battle began, he thought there might be as many as a dozen enemies hiding out. There turned out to be hundreds, yet Hollenbaugh was accompanied by only a few dozen American Marines.

Over the course of several hours, Don Hollenbaugh simultaneously fought off insurgents, used his expert firing skills to provide cover for his comrades and even gave them life-saving medical attention.

In the latest installment of "American Heroes," we'll take you inside the fight and show you how Master Sgt. Hollenbaugh saved a number of lives that day, and continues saving lives to this day, by giving young soldiers the tools, skills, and the invaluable battle experience they need to go to war.

It is the story of a military man who was willing to give his life for his country and his fellow soldiers, a man who left the Military, but couldn't stand to be away from the life he loved, so he got a job working with it … you guessed it — the Army.

You will see how the Army has been, and may always be, a Hollenbaugh family tradition — Meet Master Sgt. Don Hollenbaugh: An American Hero.
