I have played this game for 9 months now and I have tried a lot of different silo setups. I mostly place them nice and tight and try to protect every silo as much as possible. But I must say the most potent setup for variable units mode I have tried is this: 3x3 tight triangles + 1 fill in. Place them so that both the small triangles face flat out to the main trajectory lane and try to place the group as a whole in line, fill in with radars. I fired 10 silos from NA at cities only and almost nothing got through at the strong side. Had I spread them a bit east and maybe a little lower I think I might have stopped almost 100 nukes from doing any major damage.
What is your most potent silo setup (def/off)? This is mine:
(disregard everything but the silos as this was just a test game...









Use at your own risk
