Koppi,
Another bold and pertinent posting I think.
"Red Army vs. Blue Army" - really, almost the essence [perhaps pure dimension] of wargaming (btw, I'm a big fan on the C&C games too).
If just a 'finishing touch' suggestion, for you or Jens on these 3D print miniatures - perhaps make the bases separate prints (if they're not already), so they can be printed out in green, or easily spray painted a green before joining.
