Those of you who might have looked in on my "The Alpian Wars" mini-campaign might have noticed that my Pike & Shot units have a different number of figures per stand than what Clarence calls for:
Yes, I know that I'm using the rules for 16th rather than 17th century, but the base sizes (60mm square) are the same.
And while my choice was in part dictated by my available troops, I would do the same thing if starting from scratch for the ECW.
Instead of 6 figures per stand (i.e., 18 per unit), I feel that the pike should be more densely packed than the shot . . . so I use 5 shot per stand (in a "W" formation) and 8 pike/command (in a 3-2-3 pattern). To me this looks better on the table top . . . and it is actually the same number of figures (18) per unit.
Think about it a bit . . . doesn't this look better to you too? And it doesn't change the game one iota. It can also be used against a more traditionally based army without difficulty.
Try it, you might like it.
