In attempting to distinguish between civilians and combatants , some atrocities occurred on all sides , especially during the 1970s . A notable example in 1972 was Bloody Sunday in Derry , associated with the Parachute Regiment ( already regarded as heavy handed by the Irish nationalist community across the board ) . The Scottish regiments which were deployed , such as the Black Watch , were perceived by Irish nationalists as being particularly sympathetic to Orangism and Ulster loyalism , due in part to a similar socio-political culture of sectarianism in Scotland . For the Irish diaspora in Britain , bombings by the PIRA in England led some to either emphasise the credentials of their own Britishness , including championing the suppression of paramilitary forces by the state , or for a minority , participating in organisations such as the Troops Out Movement formed in 1973 ( also consisting of some English people ) , which aligned itself with Irish republicanism by advocating a British disengagement and withdrawal from Northern Ireland
