The SAS ambush had no noticeable long-term effect on the level of IRA activity in East Tyrone. The level of IRA activity in the area did not show any real decline in the aftermath: in the two years prior to the Loughgall ambush the IRA killed seven people in East Tyrone and North Armagh, and eleven in the two years following the ambush. Additionally, most of the attacks which took place in County Fermanagh during this period of the Troubles were also launched from south Tyrone and Monaghan. However, many of their remaining members were young and inexperienced and fell into further ambushes, leading to high casualties by the standards of the low intensity guerrilla conflict in Northern Ireland. Ed Moloney, Irish journalist and author of the "Secret History of the IRA", states that the Provisional IRA East Tyrone Brigade lost 53 members killed in the Troubles, the highest of any rural Brigade area. Of these, 28 were killed between 1987 and 1992.
