Following several regimental-sized assaults on Coral which were successfully repelled by the Australians with heavy casualties on both sides, 1ATF moved to establish Fire Support Base Balmoral on 24–25 May, north of Coral. The infantry were this time supported by Centurion tanks which had been called forward by road from Nui Dat and had arrived just hours before Balmoral was subjected to a two battalion attack. Following a very accurate rocket and mortar barrage at 03:45 hours on 26 May, the base was assaulted by North Vietnamese infantry. The attack was repelled with heavy casualties by the combined firepower of the tanks and infantry. The next day the Australians at Coral assaulted a number of bunkers located just outside the base, with a troop of Centurions supported by infantry destroying the bunkers and their occupants without loss. A second attack, again of regimental strength, was made against Balmoral at 02:30 hours on 28 May but was called off after only 30 minutes. The North Vietnamese were soundly defeated—again by the supporting fires of tanks, artillery and mortars—leaving 55 dead and resulted in six prisoners. Australian losses were one killed and six wounded. This performance demonstrated the advantage of using armour in Vietnam, and whereas before the battle some infantry had doubted the usefulness or necessity of the Centurions, after the battle the infantry did not like working without them. For its involvement in the fighting at Coral–Balmoral, 'C' Squadron was awarded a Unit Citation for Gallantry in 2018.
