Two Army interrogators were also reprimanded, a military spokesman said.

Army interrogators have never had such a set of specific guidelines that would help teach them how to walk right up to the line between legal and illegal interrogations.

The debate has focused on a proposed Pentagon directive that would establish guidelines for interrogating detainees as well as on a draft field manual for Army interrogators.

From January 2004 to January 2005, I served in various places in Iraq (including Abu Ghraib) as an Army interrogator.

"Around Iraq, in the back of a Humvee or in a shipping container, there's no camera," says an active-duty Army interrogator whose identity is hidden in the documentary.

During the first half of 2002, they said, almost none of the Army interrogators had any substantial background in terrorism, Al Qaeda or other relevant subjects.

Many younger Army interrogators had never questioned a real prisoner before.

"It's a fairly obsolete manual," said Mike Ritz, a former Army interrogator who runs interrogation workshops for law enforcement officials and civilians.

Mr. Ritz, the former Army interrogator, said that torture was ineffective as an interrogation technique.

I was an Army interrogator and military intelligence officer.
