This battle is frequently taught in Australian officer training, as it is an excellent case study of well-trained and disciplined soldiers; the importance of combining infantry, artillery, armour and aviation; coordination between units and the importance of firepower.
Australian field intelligence had tracked a radio transmitter moving south for several weeks but were unsure about what unit it belonged to.
Australian commanders have been accused of being foolhardy sending lightly armed and small units into an area where an entire regiment was known to be heading.
The Australian government agreed that the battalion should be under the operational control of General Westmoreland and that it should be used for the defense of base areas, for patrolling in the vicinity of base areas, and as a mobile reserve.
While Australian officials, both military and civilian, were aware of the taskforce's need for a third battalion, they did not wish at that time to add fuel to the fires of the critics of Australia's Vietnam policy.
The 3d Battalion, Royal Australian Regiment, with combat support and logistic elements closed in Vietnam in December 1967 and was attached to the 1stAustralianTaskForce in the III Corps Tactical Zone.
