The East Tyrone Brigade of the Provisional Irish Republican Army (IRA), also known as the Tyrone/Monaghan Brigade was one of the most active republican paramilitary groups in Northern Ireland during "the Troubles". It is believed to have drawn its membership from across the eastern side of County Tyrone as well as north County Monaghan and south County Londonderry.

On 13 December 1989 the Provisional Irish Republican Army (IRA) attacked a British Army permanent vehicle checkpoint complex manned by the King's Own Scottish Borderers (KOSB) near the Northern Ireland–Republic of Ireland border at Derryard townland, a few miles north of Rosslea, County Fermanagh. The IRA unit, firing from the back of an armoured dump truck, attacked the small base with heavy machine-guns, grenades, anti-tank rockets and a flamethrower. A nearby Army patrol arrived at the scene and a fierce firefight erupted. The IRA withdrew after leaving a van bomb inside the complex, but the device did not fully detonate. The assault on the outpost left two soldiers dead and two wounded.
