Does doctrine matter in this series?

[Sir John Cope]

What a great question. In my opinion, military doctrine is usually a hypothesis about the best way to use a given set of assets in the next war. I think one the (many) inevitable differences between historical wargaming and war is that a game designer has at his disposal a hypothesis which has already been tested (that is, the "next war" has already been fought). In a sense, the question of doctrine is usually settled for the player by the designer's decisions, in everything from unit ratings to game-system functions. That being said, in some games (France 40 comes immediately to mind) I will usually consciously avoid adopting the historical doctrine - if I'm playing the Allied side, that is.
