Thanks,
I just found out at the WAB Forum that you use suppression marker in the same way as I do.
12 Units is fairly large but I think its possible.
We played a huge multiplayer game with 8 players each controlling 4 Units. Suprisingly that worked very well. Ok, the players were all used to the rules but i was surprised how easy the game worked. We never tested the rules with a huge number of units.
