Whilst browsing the Net for historical battle sims I came across Battle Command which looks really interesting, and could perhaps be considered the ground assault half of CMANO. It does lack AI at the moment but that is coming and already available for one scenario. The cost of the software is $49 which includes Military mapping software and secure voip for multiplayer, of course the dream would be a combined CMANO/Battle Command hybrid - but just a dream
