At first glance they appear to be the archetypal Band Of Brothers of Hollywood myth, brave and honest men united in common purpose. 

But a closer look at these American GIs, sweltering in the heat of an unwelcoming Iraq, reveals the glazed eyes and limp expressions of those who have witnessed a war they do not understand and have begun to resent. By their own admission these American soldiers have killed civilians without hesitation, shot wounded fighters and left others to die in agony.

What they told me, in a series of extraordinary interviews, will make uncomfortable reading for US and British politicians and senior military staff desperate to prevent the liberation of Iraq turning into a quagmire of Vietnam proportions, where the behaviour of troops feeds the hatred of an occupied people.

Sergeant First Class John Meadows revealed the mindset that has led to hundreds of innocent Iraqi civilians being killed alongside fighters deliberately dressed in civilian clothes. "You can't distinguish between who's trying to kill you and who's not," he said. "Like, the only way to get through s*** like that was to concentrate on getting through it by killing as many people as you can, people you know are trying to kill you. Killing them first and getting home."
