 In the end, although many of the significant actions of the campaign were infantry engagements which occurred a long way from the Australian base areas where their technological superiority was limited, the Australians' use of combined arms tactics ultimately proved decisive.Although preliminary aerial bombardment, particularly that which was employed around Sattelberg, proved largely ineffective in terms of its physical effects, it did serve to reduce Japanese morale.Used in combination with artillery preparation, which caused significant casualties, considerable disruption was caused to Japanese lines of communications that were already stretched.
