Have not played a good game of Chainmail since the 1970's. The group that intro'ed me to minis, slightly pre-ODD, used a somewhat modified Chainmail. They put figures on 1" bases, and only in recent years, since reading Peterson's _Playing At The World_ & following up on sources, that I found out that the presumption is a sand table where you just stick the un-based fig into the sand. So that explains a lot about frontages and mixing figure scales & overlap concepts. I only find 2 threads about Chainmail, that seems very odd for such a fundamental part of the D&D experience.
