The withdrawal included support from Australian logistics experts, a psychologist to conduct end-of-tour debriefings and a finance officer.
The debriefings, by a dozen teams of specialists, began about 10 o'clock in the morning and were expected to last 12 hours, Navy officials said.
"C.I.A. officers, whose knowledge of terrorist organizations is second to none, will continue to conduct debriefings using a dialog style of questioning that is fully consistent with the interrogation approaches authorized and listed in the Army Field Manual," Mr. Panetta wrote.
ISS and OSS participants viewed debriefings as a central, exceedingly positive factor for ensuring learning.
Further, we conducted a 'peer-debriefing' session, a technique that consists of discussing our findings with other colleagues not involved in the analysis of the data (77).
One of his most memorable debriefings was interrogating a German who had survived a 20,000ft fall over Holland without his parachute opening.
"The C.I.A. took active part in the work of the task force, and the agency's strong counterterrorism knowledge will be key to the conduct of future debriefings," said Paul Gimigliano, a C.I.A. spokesman.
We sought to mitigate this limitation via trainings and daily debriefings led by a public health researcher who accompanied teams throughout data collection.
For example, in the summer of 2001, Mr. Bush's national security team was told about the extensive F.B.I. debriefings of Ahmed Ressam, an Algerian arrested in December 1999 at the Canadian border by a Customs Service agent in what became known as the millennium bombing plot.
Mr. Ujaama also has to give "debriefings" to investigators, an obligation that extends to foreign governments.
