Brilliant collection Steve, I really like what you’ve done to these. Rapid Fire is such a great set of rules that the forces can easily be converted to play O Group. O Group is also another fun set of rules to play at a very similar scale. No, your right an army is never complete 😂.
Sorry for the late reply,, 25mm for the troops, 30mm for sp wpns, 40mm - 60mm for towed AT guns, depending on size. The vehicle bases are all different, depending on the size of the vehicle. I hope that helps.
