On 11 August 1986, the East Tyrone Brigade of the Provisional Irish Republican Army (IRA) attacked the Royal Ulster Constabulary (RUC) base at The Birches near Portadown, County Armagh, Northern Ireland. The unmanned base was raked with gunfire before being destroyed by a 200 pounds (91 kg) bomb, which was driven through the gate of the base in the bucket of a JCB digger.
