The unsigned Sept. 10 draft authorized approaches spelled out in Army Field Manual 34-52 and other widely used interrogation techniques, as well as sensory deprivation, which could mean the hooding of prisoners.
On Sept. 14, General Sanchez approved the first formal policy for Iraq that allowed the use of "sleep management" techniques, like limiting prisoners to four hours' rest each 24 hours, and stress positions, including standing or crouching for up to an hour at a time, Senate aides said.

That policy was sent to the Central Command and to other military, legal and intelligence experts for review. On Oct. 12, in response to objections from military lawyers, General Sanchez issued a second, much narrower policy that Colonel Warren said Wednesday complied with the Geneva Conventions.
Most of the harsher methods that had been automatically authorized in the Sept. 14 directive, like long-term isolation of a prisoner, were dropped in the October version, except in cases in which General Sanchez sanctioned them.
The Oct. 12 directive also ordered that interrogators take control of the "lighting, heating, and configuration of the interrogation room, as well as food, clothing and shelter" given to those questioned at Abu Ghraib, a Senate aide said. The memo directed interrogators to work closely with military police guarding the prisoners to "manipulate internees' emotions and weaknesses" to gain their cooperation.
