The Pentagon sent a US veteran of the dirty wars" in Central America to oversee sectarian police commando units in Iraq that set up secret detention and torture centres to get information from insurgents. These units conducted some of the worst acts of torture during the US occupation and accelerated the country's descent into full-scale civil war. Colonel James Steele was a 58-year-old retired special forces veteran when he was nominated by Donald Rumsfeld to help organise the paramilitaries in an attempt to quell a Sunni insurgency. After the Pentagon lifted a ban on Shia militias joining the security forces, the Special Police Commando (SPC) membership was increasingly drawn from ... Shia groups such as the Badr brigades. A second special adviser, retired Colonel James H Coffman, worked alongside Steele in detention centres that were set up with millions of dollars of US funding. Coffman reported directly to General David Petraeus, sent to Iraq in June 2004 to organise and train the new Iraqi security forces. Steele, who was in Iraq from 2003 to 2005, and returned to the country in 2006, reported directly to Rumsfeld. The allegations, made by US and Iraqi witnesses in the Guardian/BBC documentary ["James Steele: America's Mystery Man in Iraq"], implicate US advisers for the first time in the human rights abuses committed by the commandos. It is also the first time that Petraeus - who last November was forced to resign as director of the CIA after a sex scandal - has been linked through an adviser to this abuse.
