Army Briefing Note 34-05: PSNI Historic Enquiries The audience for this ABN are: 'members of the Army who served in NI at any time between 1969 and 1998'. Key points: A. The NIO announced earlier this year that the PSNI intend to review more than 2000 âunresolvedâ deaths that occurred between 1969 and 1998 in Northern Ireland. More than 300 of these are attributed to the security forces; B. It is possible that some serving and former soldiers will be interviewed as part of the PSNI Historic Review â most are likely to be interviewed as witnesses, although it is possible that some will be interviewed as suspects. In either case, the MOD will provide serving and former soldiers with whatever support is appropriate; C. The PSNI has started to investigate the deaths on a chronological basis from 1969 onwards. It is anticipated that it will take up to five years for preliminary investigations to be completed into all 2000 deaths; D. Any decision to prosecute will be made by the PSNI and Director of Public Prosecutions, not by the Army chain of command or the Army Prosecuting Authority.
