The armed half-track

[Huib Versloot]

Here is the Doug Bevard description of what his battle represented:

Mausbach, 12km E of Aachen, Germany: [Best played against Human opponent] While in the north the British were preparing for Operation Market-Garden, further south the Americans were knocking on Germany's door. With the decision to bypass Aachen, the plan of the US VII Corps called for a frontal attack by armor to sweep through the West Wall defenses south of the city then a northward sweep to complete the encirclement. By September 14th CCB/3rd Armored Division had penetrated deeply into the West Wall and was poised to drive north. At Roetgen, CCB split into two task forces with TF King advancing toward Stolberg, while on the right TF Lovelady was to fight its way to Eschweiler. By noon on the 15th, Colonel Lovelady's tired GIs prepared to cross the Vicht River and drive through the last positions of the Schill Line and into the open ground around Mausbach and Gressenich. German reserves were nearly exhausted. However, a scratch force from the shattered 9th Panzer Division, 105th Panzer and 394th Assault Gun Brigades was ordered south to blunt the American attack.

12 turns = One hour and twelve minutes of fighting.

Not the first hour and 12 minutes after TF Lovelady fired it's first shot at the Schill Line. Therefore 12 turns is an abstract choice that Bevard made to represent these events that happended spread over several days in the best way given the game mechanics. This observation (that is valid for most scenarios) makes the duration of a turn irrelevant for scenario designing.
Anyone who has ever tried to design a historical scenario has at some point been forced to determine how many turns are needed to represent historical events. If Bevard had used Ed and Hawk's perception of time scale in CS, his TF Lovelady scn would have been over a hundred turns instead of twelve.
