One of the officers present during the Combatant Status Review Tribunals convened at the Guantanamo Bay detention camps, in Cuba, was known as the Recorder.
As in the AR-190-8 Tribunals a panel of three officers were authorized to make a determination whether or not an individual had been properly classified as a combatant.
For the CSR Tribunals that officer was known as the "Recorder", and was always a military lawyer.
CSR Tribunals added a fifth officer, the Personal Representative, whose responsibility was to meet with the captive, try to explain the CSR Tribunal process to them, learn their account of themselves, and present their account to the Tribunal if the captive chose not to attend, or proved unable to present their account themselves.
In the AR-190-8 Tribunal only the President was required to be a field grade officer.
