On 6 June 1993, an IRA unit converted a stolen van in a "mobile mortar launcher" in the area of Pomeroy and slipped through British forces' surveillance to the RUC barracks at Carrickmore. According to the brigade report, the van, fitted with a Mark-15 mortar, was left besides a mllitary sangar. The area was previously secured by a group of armed volunteers. The unit dispersed after setting on the mortar's timer. The projectile landed within the grounds of the base, causing some damage according to the RUC. The IRA asserts instead that the barracks were "extensively damaged".
