Good leadership by officers & especially senior NCOs on the ground. Not so good by those further back, who then managed to snare some gongs for themselves, while ignoring recommendations for those who were actually under fire. Also good work on ammo resupply by the RAAF. I think they broke a few rules to do so, from memory.
I did some work for the bloke who was Bn Ops officer, who said he could only watch on helplessly while it all went down.
