It's an interesting camouflage scheme, and one which I am quite likely to never, ever paint again unless I can work out some less tedious way of achieving it. I thought I would be able to just mask and airbrush it, but all the surface protrusions made that a nightmare — maybe it would be less troublesome if I could have painted all the components separately and then assembled them. Anyway, for this one I just ended up doing it freehand.
NOTE: this is Battlefront's original sculpt of the A9. They've remastered it since then and added a bit more detail. Nevertheless, I think this old one is a pretty decent representation of the original vehicle.
