The name Catholic Reaction Force (CRF) was used in Northern Ireland to claim responsibility for attacks and threats against Ulster Protestants during the Troubles. In 1983 it was used to claim responsibility for the shooting dead of three Protestant civilians at a church service near Darkley, County Armagh, claimed as retaliation for attacks on Catholic civilians by the Protestant Action Force. An Irish National Liberation Army (INLA) member was involved, but the INLA said it had not ordered the attack.
