I second the suggestion of using Cross Fire rules. Having played them since 1997 I can tell you that they put the player directly into the role of tactical commander. They also use no turns and no measurement!! My blog http://kingstonirregulars.blogspot.com/ has many Crossfire games that my club has played (there is a lot of other stuff – just search for Cross Fire or Crossfire). Another blog http://www.mgluteus.blogspot.com/ discusses among othr things, usinf Cross Fire for the Korean War.
