From GMT's Website:
The Men of Iron Series is designed for quick learning and easy play. Game rules are short, there are no turns - play is continual, with ample opportunities to steal play from your opponent - and combat resolution is a single dieroll. Playing time is about 1-to-2 hours, per battle.
Men of Iron is also GMT's gift to the gamer who enjoys playing solitaire - the system is designed for both individual and face-to-face play without any loss in insight or fun - to see what happened in these famous battles and why.
