This week I suggest checking out this excellent 5 part series on Mobility on Craftworld Lansing. I love global strategy articles which look at the how and why, the really high level thinking that can go on in a game.
This series looks at the different stages in the game (list building, start, middle and end) and how to use a mobile army in each of these. What I also liked was that the stages are approached differently depending on whether you are winning, losing or fighting tooth and nail.
Good reading for generals playing and fighting against mobile armies. More please!
