British military intelligence systems in Northern Ireland

The British Military is alleged by author Tony Geraghty to have exploited a number of information sources during the Troubles in Northern Ireland. Geraghty describes these in his book, The Irish War, basing his description on an extract from an unspecified, classified document passed to him by an unspecified informant, later identified as a former Army officer, Nigel Wylde.

Geraghty said that these systems were extensively used by both British Military Intelligence and Police.
