Perspective: Top secret British army cell a deadly foe

Deep inside the heart of the "Green Zone", the heavily fortified administrative compound in Baghdad, lies one of the most carefully guarded secrets of the war in Iraq. It is a cell from a small and anonymous British Army unit that goes by the deliberately meaningless name of the Joint Support Group (JSG), and it has proved to be one of the Coalition's most effective and deadly weapons in the fight against terror.

Its members - servicemen and women of all ranks recruited from all three of the Armed Forces - are trained to turn hardened terrorists into coalition spies using methods developed on the mean streets of Ulster during the Troubles, when the Army managed to infiltrate the IRA at almost every level. Since war broke out in Iraq in 2003, they have been responsible for running dozens of Iraqi double agents.

Working alongside the Special Air Service and the American Delta Force as part of the Baghdad-based counter-terrorist unit known as Task Force Black, they have supplied intelligence that has saved hundreds of lives and resulted in some of the most notable successes against the myriad terror groups fighting in Iraq. Only last week, intelligence from the JSG is understood to have led to a series of successful operations against Sunni militia groups in southern Baghdad.

Information obtained by the unit is also understood to have inspired one of the most successful operations carried out by Task Force Black, in November 2005, when SAS snipers shot dead three suicide bombers.

The killing of Abu Musab al-Zarqawi, the leader of al-Qaeda in Iraq up until his death in June last year, followed intelligence obtained by the JSG, as did the rescue of the kidnapped peace campaigner, Norman Kember.

"The JSG is the coalition's secret weapon," revealed one defence source. "Their job is to recruit and run covert human intelligence sources or agents - we never use the term informer. The Americans are in awe of the unit because they have nothing like them within their military."
