After the horrors of 9/11, the British armed forces were called upon to by the government to engage new enemies in faraway lands. Royal Marines led British troops into Afghanistan in 2002 to oust the Taliban and scatter al-Qaeda. Then in March 2003, again it was the Royal Marines who kicked off the Second Gulf War with an assault in southern Iraq to pave the way for the removal from power of the brutal Saddam Hussein. Since then, the men and women of the British forces have been routinely exposed to mortal danger. Some of the most inspiring stories of courage stem from individual acts of rescue of one wounded soldier by another. "On the Frontline" tells a story of modern bravery and devotion to duty.
