I agree that real-time games (of which Close Combat is one) have their place, but I don't think it would be possible to control a battalion which each of the subunits being squads and individual vehicles. Talk about a click-fest.
Try out Supreme Commander (demo if you can't afford full game). Every unit is individual and maximum unit limit (counting buildings) is... I'm not sure, but somewhere at battalion level I believe. And it's not just about moving and micromanaging your dogs of war, you need take care of economy as well so you have always something to throw at grinder (but no supply unless you count repairs as that). There are lots of tactics available too, but executing combined arms warfare in multiple fronts is just impossible without frequent use of Pause key.
You know what they say, don't you? About how us MechWarriors are the modern knights, how warfare has become civilized now that we have to abide by conventions and rules of war. Don't believe it.
