In 2004, with the war in Iraq going from bad to worse, the US drafted in a veteran of Central America's dirty wars to help set up a new force to fight the insurgency. The result: secret detention centres, torture and a spiral into sectarian carnage
Reference to Manning should be as Chelsea, not Bradley.
Neil Smith, a 20-year-old medic who was based in Samarra, remembers what low ranking US soldiers in the canteen said. "What was pretty widely known in our battalion, definitely in our platoon, was that they were pretty violent with their interrogations. That they would beat people, shock them with electrical shock, stab them, I don't know what else ... it sounds like pretty awful things. If you sent a guy there he was going to get tortured and perhaps raped or whatever, humiliated and brutalised by the special commandos in order for them to get whatever information they wanted."
He now lives in Detroit and is a born-again Christian. He spoke to the Guardian because he said he now considered it his religious duty to speak out about what he saw. "I don't think folks back home in America had any idea what American soldiers were involved in over there, the torture and all kinds of stuff."
Through Facebook, Twitter and social media the Guardian managed to make contact with three soldiers who confirmed they were handing over detainees to be tortured by the special commandos, but none except Smith were prepared to go on camera.
"If somebody gets arrested and we hand them over to MoI they're going to get their balls hooked, electrocuted or they're going to get beaten or raped up the ass with a coke bottle or something like that," one said.
He left the army in September 2006. Now 28, he works with refugees from the Arab world in Detroit teaching recent arrivals, including Iraqis, English.
"I suppose it is my way of saying sorry," he said.
