The ICBM always struck me as an interesting but not very practical unit. It has crazy damage, but the base lvl requires 4 nuclear warheads and a lvl 5 secret weapons base to produce the launcher. In a Red VS. Blue game I joined as Mongolia for this sole purpose( on day 30, i might add), I created 2 ICBM launchers and summarily attacked USA east and demolished 3 of his cities. The disappointing part was that I only killed 6 units. Have you ever used ICBM's? If so, what was your experience with them?
