This seems to be the prevailing view within the aussie army.
Curious, I'm hearing the exact opposite, albeit from a relatively junior friend. He was, however, operational during the period. His view is that the feeling among the ranks is that any failings are very much individual and that the "collective guilt" caused many to exit stage left as it became the dominant paradigm. Culture was most certainly an issue, but it was a small minority that caused this. I guess the inquiry report will shed some light.
