Roland Davis sent through his ideas for Crossfire in 1914 (i.e. early WW1). He outlines the general concept of large scale CF, includes a short battle report and concludes with some commentary on how it worked. Everything following is Roland’s …
Martin Rapier has created a simple set of rules to allow a group of players to play operational level games. His rules are embedded within the context of Operation Uranus (19 Nov 1942). I’ve abstracted his rules so I can then apply them to different settings (and tweaked them a bit as I did so).
These rules are ideal for a typical offensive where the attackers have three to one odds against the defenders – something that is not possible in most rule systems. One of the beauties of this system is that it is a cooperative effort more than competitive; the players are the attacking team, and fight against the umpire who runs the defenders. Given the odds the attacking Division is going to beat the defending Division. The question is, will they beat them fast enough and well enough.
This isn’t a long game to play, taking a couple of hours at most. You’ll also need stands of miniatures (~65), counters (~16), a small table, some way of marking off a grid on the table, a map, and 5-6 people. An intercom and telescope are optional.
