According to The Thin Green Line - The History of the Royal Ulster Constabulary GC, written by RUC reservist Richard Doherty, 314 officers were killed and over 9,000 were injured during the existence of the RUC.
The Newry mortar attack by the Provisional IRA on an RUC station in 1985, which killed nine officers (including two Catholics), resulted in the highest number of deaths inflicted on the RUC in one incident.
