On the food side - One thing I did find when we were training in the cadets and issued Anzac biscuits in ration packs they were near on impossible to eat but made great fire lighters, when we had our mock wars and issued blanks some of the guys got to putting a blank in the chamber and gravel down the bore of the Mk III's we had for a sorta shotgun how some of us were not injured by this folly I do not know. I guess my proudest moment was gaining my crossed rifles with the Mk III it was sanctioned by the regular Army and we shot the same course of fire as the regular Army it was the first year it had been allowed and I was the only one from my cadet unit to attain the score, I have 1 set framed with the picture of them being presented to me and another set sewn onto my shooting jacket that was in 1972.
I think from memory needed 75/100 course of fire was 10 rounds prone 300yds stand up load 10 cycle bolt safety on run in extended line with rifle at high port to 200yds 5 rounds/sitting 3 rounds/prone safety on stand up run to 100 2/standing at 10" disc I managed 75 and with our range 303's I probably snagged one that was a reasonable shooter as we only had 10 green Mk III's in the Q Store all the others were yellows and reds @ 50 of them all up oh and the 3" mortar.
