The M2A2 105 millimetre howitzer was the standard artillery weapon used by most field regiments of the Royal Australian Artillery (RAA) during the Vietnam conflict. This gun was used in the fire support role at Fire Support Base Coral, Bien Hoa Province, Vietnam in 1968. On the night of 12/13 May 1968 FSB Coral was attacked at about 3.30 am following a brief but intense rocket and mortar barrage. A mortar platoon position was over-run, along with this gun, number 6 of the 102 Field Battery, 12th Field Regiment, RAA. With the aid of extensive air support, the attack was beaten off and this gun was retaken. The gun had been damaged by a satchel charge by the North Vietnamese troops. Both tyres were destroyed, as well as damaging the shield resulting in the weapon being withdrawn for repair before being returned back to service. See AWM photograph P09295.001.
