Copy from here: <a href="http://www.universalbattle.com/list/armies" rel="nofollow">http://www.universalbattle.com/list/armies</a> To size things just play about with the system, if you set the page settings to a 'unit' per pixel, say 50, then each unit as 1 inch then when you scale in your units a 25mm base is near enough a 50 pixels. The ruler in game will then match for measurements. I am thinking of doing the same but for Kings of War as it is a easier system, you remove whole units not individuals and the rules are free online.
