Dawn of War: Professional (DoWPro) is a gameplay and balance mod for Dawn of War, which strives to bring new depth to the multiplayer experience, particulary into Player versus Player (or PVP for short).
Yet again another comparisson.
Going there. Close enough.
How does it possible?
It was just a mere texture change, nothing else. For some reason (as far as I know, someone can correct me), the textures provided from the vanilla Land Speeder are the same ones that for instance FoK uses.
Unfortunately, I cant say the same for Scouts and tacticals which use a different animator and thus, a different set of textures. :(
