I have shared on a number of occasions the visitors quarters at various RAAF bases with a sabre squadron and at no time was rank obvious, I was told that they are never identified that way as a rule, hence my curiosity at seeing the Corporal identified rather than the use of the generic or entry rank of trooper. The lack of identification prior to the presentation was in that context, I wonder if as you say things are different for the special cases, as surely a VC recipient is?
Regardless its fantastic to see the work being recognized, I am sure many SASR and indeed many ADF personnel are not recognized for their excellence as often as they should be.
