In one of the most intense actions of the latter stage of Australian involvement in Vietnam, soldiers of the 3rd Battalion, Royal Australian Regiment, supported by centurion tanks of C Squadron 1 Armoured Regiment, assaulted a concealed bunker complex in South Vietnam's Long Khanh Province. The most significant fighting took place on 7 June 1971, with 5 Platoon B Company 3RAR isolated by fire from enemy positions as close as 15 metres. Low on ammunition, close support from Australian and US artillery and helicopter gunships helped them survive. This became known as The Battle of Long Khanh. Three soldiers were killed during the battle - one gunnery officer, shot during a firefight and two RAAF crewmen when their helicopter was shot down. Ten soldiers were wounded. After a tense night holding a defensive perimeter, the battle as over. In the morning, the enemy - 3/33 Regiment, North Vietnamese Army, was gone. Overload continued, and on 12 June, a rocket propelled grenade killed seven more soldiers aboard an APC and wounded others.
