The RUC security base at Caledon became the target of the "Barrack Busters" twice. On 11 May 1993, an IRA militant pretending to be a motorist that had been asked to show his licence at the barracks left a van carrying a mortar outside the facilities. The device landed unexploded inside the complex, forcing its evacuation. The facilities came under attack once again on 7 November, when a supporting team armed with automatic weapons secured the area around the barracks, allowing an Isuzu Trooper carrying a "Barrack Buster" to be driven just outside the base. The support team sprayed the instalations with a burst of gunfire, but the mortar overshot the compound, damaging an adjacent church. Fifty people was evacuated.
