This is really great info, thank you for your input! This will make my game playing much more enjoyable now that I can use my units the way they were designed to be used.
I do currently use my HQ to spot for mortars that are hidden somewhere within command, it's too bad the chain of command cannot be linked so that say the front line HQ can relay positions to a backline HQ who then gives the motars the ability to fire, as it would be in a real infantry unit.
In regards to using MG's, you mention that once the front line has cleared an area that you move your MG team in there, what I have found is that although I may be able to clear a particular area, there are still plenty of enemies on a hill somewhere and once my front line moves past their current 'cleared area' so my MG's can move in, the enemy can still spot the MG's and then pin them in the wide open on their way to new positions
I have repeatedly tried to put my zooks in with my line troops, but behind them and still within sight of the HQ, but when things get dicey on the front lines they tuck tail and run, is there a good method to keep them protected? My only option, until reading all this great insight, has been to stick them with their own HQ a decent piece behind the front line and bring them up if tanks are bearing down on the line. Of course the down side is that by the time they get there the tanks have already taken out or broken part of my line.
From reading what you all have written, it would seem that your setup phase must take hours. I know for me that I can easily spend 45 minutes to an hour sorting through my troops and getting them into position and it appears as though I'm not nearly as dilligent as you all are in doing that.
