The Troubles: IRA killings 1969-2001, by victim status
Over 1,800 of all killings committed during the Troubles have been attributed to the Irish Republican Army (IRA). While the Troubles is often described as a "Catholic versus Protestant" or "republican versus loyalist" conflict, the number of loyalist paramilitaries killed by the IRA was just 45 people in total, or 2.5 percent of total IRA killings. In fact, it was British security forces, such as army personnel or the police force (Royal Ulster Constabulary), who suffered the largest number of killings by the IRA, with over 1,000 deaths, or over 55 percent of the IRA's total.
