Official Irish Republican Army The Official Irish Republican Army or Official IRA (OIRA) was an Irish republican paramilitary group whose goal was to remove Northern Ireland from the United Kingdom and create a "workers' republic" encompassing all of Ireland. It emerged in December 1969, shortly after the beginning of the Troubles, when the Irish Republican Army split into two factions. The other was the Provisional IRA. Each continued to call itself simply "the IRA" and rejected the other's legitimacy. Unlike the "Provisionals", the "Officials" were Marxist and worked to form a united front with other Irish communist groups, named the Irish National Liberation Front (NLF). The Officials were called the NLF by the Provisionals and were sometimes nicknamed the "Red IRA" by others.
Connaught Rangers The Connaught Rangers ("The Devil's Own") was an Irish line infantry regiment of the British Army formed by the amalgamation of the 88th Regiment of Foot (Connaught Rangers) (which formed the "1st Battalion") and the 94th Regiment of Foot (which formed the "2nd Battalion") in July 1881. Between the time of its formation and Irish independence, it was one of eight Irish regiments raised largely in Ireland, its home depot in Galway. It was disbanded with the Partition of Ireland following establishment of the independent Irish Free State in 1922, along with the other five regiments that had their traditional recruiting grounds in the counties of the new state.
