On a reconnaissance in force near Coral, C Company, 1 RAR, was pinned down by heavy mortar, machine-gun and rocket fire from a bunker system, at ranges of 10 to 15 metres, too close for gunships and artillery to help much, and carriers could not get through the jungle. Two tanks arrived from Coral and an assault destroyed eight bunkers; a carrier was hit by a rocket while taking out the wounded. The company then broke contact for air strikes. One Australian was killed and seven wounded; 24 enemy were killed and more probably killed, and five bodies were found when the company returned days later.

The enemy were routed, and local forces cleared the rest of the village to avoid civilian casualties. Forty enemy were recorded killed.

Significant · Tank support for 8 RAR

Australian: 3 wounded. Enemy: 10 killed, 22 wounded.

9 Platoon, C Company, 8 RAR, was carried by tanks to within a kilometre of a carefully chosen ambush site and slipped in unseen while the tanks made a diversion, with engineers checking the site for mines and 15 Claymores laid along the track. It let the first of four enemy groups pass, and wiped out the second and third with its Claymores; the first and fourth counter-attacked. Running low on ammunition, the platoon was supported by mortars, artillery and helicopter gunships, and within 40 minutes the tanks of 1 Armoured Regiment came back, cleared the killing ground and stayed through the night. Three Australians were wounded; ten enemy were counted dead, and 22 drag marks were found.

18 February 1970: Bunker, Operation Hammersley #

Significant · Tank support for 8 RAR

Australian: 2 killed, 13 wounded. Enemy: 12 killed, 10 wounded.

C Company, 8 RAR, captured a Viet Cong who said 40 enemy were in a nearby bunker system protected by mines. The company attacked with carriers of B Squadron, 3 Cavalry Regiment, and tanks of 1 Armoured Regiment; a carrier was destroyed by two rocket-propelled grenades, killing two Australians and wounding more. After air and artillery strikes a second assault led by the tanks went through the bunkers to a deep creek, but the system was also protected by an anti-tank minefield, and the force was ordered to withdraw, taking more casualties from enemy who had reoccupied the bunkers. Twelve enemy were killed, mostly by the tanks' canister and high-explosive rounds; one tank was hit eight times and kept fighting. The system was later hit by B-52 bombers.

21 February 1970: Patrol, Operation Hammersley #

A tank of 1 Troop, C Squadron, 1 Armoured Regiment, set off a 40-pound mine on a jungle track east of Cam My. The mine had probably been in place a long time, with a recently fitted pressure trigger. There were no casualties, but the tank's suspension and four road wheels were damaged.
