Captain Robert Laurence Nairac was a British Army officer in the Grenadier Guards who was abducted from a pub in Dromintee, south County Armagh, during an undercover operation and killed by the Provisional Irish Republican Army (IRA) on his fourth tour of duty in Northern Ireland as a Military Intelligence Liaison Officer.

The Kingsmill massacre was a mass shooting that took place on 5 January 1976 near the village of Whitecross in south County Armagh, Northern Ireland. Gunmen stopped a minibus carrying eleven Protestant workmen, lined them up alongside it and shot them. Only one victim survived, despite having been shot 18 times. A Catholic man on the minibus was allowed to go free. A group calling itself the South Armagh Republican Action Force claimed responsibility. It said the shooting was retaliation for a string of attacks on Catholic civilians in the area by Loyalists, particularly the killing of six Catholics the night before. The Kingsmill massacre was the climax of a string of tit-for-tat killings in the area during the mid-1970s, and was one of the deadliest mass shootings of the Troubles.
