Episode 6 - Courage Under Fire

Former SAS soldier Andy McNab uncovers the real stories behind British and American soldiers fighting in Iraq and Afghanistan. Engineers are the unsung heroes of the battlefield, often finding themselves fighting in tractors rather than tanks, and having to blow-up their way through what others go round. Engineer Donald Campbell tells how he drove his digger into the middle of a raging fire-fight, allowing troops to move on and out thanks to the bridge he had constructed.
