Official IRA member and a veteran Republican Sean Garland. He was seriously injured in an INLA attack in Dublin on 13 March 1975 by Volunteers from the INLA Belfast Brigade. The attacks on McMillen and Garland were not sanctioned by the INLA Army Council and INLA Chief of Staff Seamus Costello was reportedly furious when he heard the news of the attacks. The Belfast Brigade staff believed that since it was the one directly under attack from the OIRA that it should decide when and whom to attack, not the INLA leadership which was based in Dublin and not under threat from the feud. McNamee who helped kill McMillen was himself shot dead soon after by the OIRA in Suffolk, Belfast. The feud between the OIRA and INLA ended soon after this killing when a truce was agreed upon. The INLA would be involved in two more feuds during its 24-year armed campaign, against the IPLO in 1986/87 and an internal feud in 1996, both of these feuds were also mainly played out in Belfast as well. The brigade's first action against a member of the British security forces occurred on the 9 August 1975 when Belfast INLA units injured two soldiers from the British Army: the first attack in Ballymurphy a sniper shot a soldier in the neck and the second along the Lower Falls a soldier suffered a serious head injury. There was an attack on soldiers in Divis Flats as well but the unit claimed no hits. It wasn't until a year later that the brigade killed a member of the British Army in the Turf Lodge area of Belfast, when a sniper shot dead private Andrew Crocker who was shot in the neck and died the next day. In September 1976 however the INLA was accused of a double sectarian murder when Volunteers from the Belfast brigade shot dead two Protestant civilians at their home in Ormonde Park, Finaghy. The INLA claimed it was a case of mistaken identity. In the late 1970s and early 1980s, the INLA developed into a modestly large urban guerrilla organisation in Northern Ireland, operating primarily from the Divis Flats complex in west Belfast, which, as a result, became colloquially known as "the planet of the Irps" (a reference to the IRSP and the film Planet of the Apes). The brigade went through a number of leaders in its first year
