Video: Iraq war vet relives his most intense gunfight

Colby Buzzell was almost killed when his entire battalion was ambushed by insurgents in Iraq.

"I heard and felt the bullets whiz literally inches from my head, hitting all around my hatch and making a ping, ping, ping sound," Buzzell said, recalling how the enemy armed with rifles and RPGs attacked from rooftops, alleys, windows from every imaginable direction.

Even worse, a few minutes after the battalion fired their way out of the kill zone, they were ordered to go back to where they got ambushed.

"I literally felt sick to my stomach," Buzzell said. "I felt like throwing up. My gut, my body, my mind, my soul, my balls were all telling me loud and clear not to go back. I was scared to death, but we had to go back. And, we did."

Watch how (a scared) Buzzell musters the courage to do things most Americans couldn't imagine doing in this riveting short video:
