Men of Iron's first volume covers the re-emergence of infantry in the early 14th century, along with a more perceptive understanding of the value of combined-arms warfare especially with good use of defensive terrain. The scenarios highlight the key elements that made these battles so fascinating: the defensive power of the longbow, especially when used in coordination with dismounted, or even mounted, men-at-arms. Given the right deployments and forces, the inability to take advantage of the marvelous abilities of the vaunted knights, the finest mounted force in Europe, became something of a surprise to many "experts."

Men of Iron 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 hour per battle. Really!
