Included in the game are 3,600 mounted counters in easy-to-cut strips of individual rows of 10 counters. Accuracy in the order of battle was a top priority, and all divisions that fought in the war are identified and included in the game. Units include infantry and cavalry divisions, headquarters units that double as artillery batteries, tank units, fighter, bomber, and reconnaissance squadrons, individual historical aces, supplies, trenches, fortifications, and gas units. Land units are either 2 or 4-step units while air units are 2-step units. Each counter face has two steps on them and thus 4-step units consist of two counters. All of the great historical aces like Manfred von Richtofen and Billy Bishop are included in the game, and these powerful units rule the sky until they are shot down. The 3,600 counters include all of these combat and non-combat units as well as informational counters.
