I knew an Aussie who served there. The unit refused to go out on patrol or bivouac with Americans, as they were stupid, careless, racist, arrogant and often stoned. They were dumb enough to go on patrol with lit cigarettes in their mouths, day or night and call to each other. The Aussies would not bed down until an hour after sunset, and move out before dawn. Only half the unit would sleep at a time. They had little respect for the Yanks had very few casualties compared to them. The Aussies saw some horrific torturing by the US troops.
