There had been three previous acts of decommissioning by the PIRA which were also overseen by the commission. The first act was in October 2001, the second in April 2002, the third in October 2003 and the fourth and final in September 2005. In the fourth and final act of decommissioning, General de Chastelain reported that he had seen rifles, particularly AK-47s, machine guns, surface-to-air missiles, explosives, explosive material, mortars, flame throwers, hand guns, timer units and blasting caps, and some weaponry that was "very old", including a WWII Bren light machine gun.
