The British Military is alleged by author Tony Geraghty to have exploited a number of information sources during the Troubles in Northern Ireland.
The Ministry of Defence Police accused Geraghty of using an extract from a classified document passed to him by Wylde as his source.
Following publication of The Irish War, Geraghty and Wylde were investigated by the Ministry of Defence Police and charged with offences under the Official Secrets Act 1989.
Geraghty said that a system called Crucible was used to consolidate items of information about individuals including personal details, imagery, mapping, movements and activities.
Geraghty said that in 1997 the Vengeful system was connected to a camera network called Glutton that would automatically track the movements of vehicles identified as being related to subjects of interest.
