The Wire by Jim Wallman is not exactly a set of miniatures rules. Rather, it is a set of umpired rules designed to provide the participants with the feel of command during the Great War. Wallman writes:

This is the combat resolution system for a command post game about commanding brigades and divisions in WW1, particularly focussed on 1916. The rules are intended to be run in real time, and by umpires, who then write messages to the HQ players in the form they would have been historically, and subject to the delays and inaccuracies that would have existed at the time. The players never see the rules at all, and must work from a map (ideally in a smelly cellar by the light of a flickering oil lantern while umpires chuck buckets of earth at then).
