And when you consider how all the other units, tanks, fighters, bombers, and infantry are all their own scales, having consistency in class seems to make the most sense. At least to me. Even if units are the same size in real life, as you said, its easier for non-historians/enthusiasts to pick up the game if unit type x is scale size x.
Maybe if this was just a naval game or a land war game, then all units could be the same scale. As 3D printing becomes more common, I was interested in hearing how others approached this.
Thanks
