Historian Albert Palazzo comments that when the Australians entered the Vietnam War, it was with their own "well considered ...concept of war", and this was often contradictory or in conflict with US concepts. The 1 ATF light infantry tactics such as patrolling, searching villages without destroying them (with a view to eventually converting them), and ambush and counter ambush drew criticism from some US commanders. General William Westmoreland is reported to have complained to Major General Tim Vincent that 1 ATF was "not being aggressive enough". By comparison, US forces sought to flush out the enemy and achieve rapid and decisive victory through "brazen scrub bashing" and the use of "massive firepower." Australians acknowledged they had much to learn from the US forces about heliborne assault and joint armour and infantry assaults. Yet the US measure of success—the body count—was apparently held in contempt by many 1 ATF battalion commanders.
