The Battle of Minh Thanh Road took place on 9 July 1966 when a Viet Cong force attacked a 1st Infantry Division convoy triggering a prepared US ambush, in which an overwhelming response of armour, artillery and airpower reacted to an ambushed convoy. The Viet Cong, primarily armed with RPG-2, recoilless rifles and small-arms had engaged and destroyed some vehicles in a convoy but were prevented from overwhelming the convoy through a massive response of US armoured, artillery and aerial support. Much of the attacking ambush had slipped past the aerial and armoured cordon set-up.
