have you see nmy "impregnable defense" thread? Militia pikes can win vs urbans.
I vote SS Pikes, hands down. They can fight the furthest with the least casaulties, against the most enemies (at least the way i play, they do) And, i'm a huuuuge pike advocater. I'm a little biased, i'll admit.
Also, so far as Machiavelli's book is concerned, the guy (whose name i'm too lazy to find again) was right about what machiavelli said. I have a copy of the book as a word document if anyone wants it.
