I was thinking RAAF Reserve, silver with high vis squadron markings, perhaps even bright coloured accents like some RAF Lightnings had, say gloss coloured spine, tail and wing tip tanks.
However in light of the revelation on the types rough field performance and capacity to forward deploy to rough strips I am tempted to do an Australian Army F-5.
I do have a stalled F-5 two seater (I honestly can't remember if it is a B or F) from years ago in a packing box somewhere that I started painting in a Fanta can scheme. I probably should dig that out and finish it first.
Anyway I imagine the F-5A, B, E, F and F-20 as the mainstay of the RAAF reserve, LIFT, dissimilar combat training and Army close air support / battle field air superiority.
