Hi Mark and Tanner - thanks for your replies. Sorry for the late reply. I didn't receive a notification that somebody answered my post hence why the silence. I'll check my profile again to check that it's set up correctly.
May give Too Fat Lardies a go - I do have a pdf of the rules somewhere. Is it an IGO UGO game? That's what attracted me to CD2 and CD3 (though CD4 became IGO UGO). Also CD did away with drawing on maps for orders - something that is in Spearhead. CE uses order chits which make the command system a little easier than having to argue over arrows on a map.

Also , have Kampfgruppe Commander (but the movement in that is IGO UGO though the rest of the turn is simultaneous). I just can't get into FoW. I've tried it and though it seems to flow for infantry engagements, for tank battles it just feels odd. The skill of the target to obviate the ability of the shooter to hit them (despite the skill of the tank commander) just doesn't seem right - I can't see tanks shimmying across the battle field (especially if they are in the open with no vegetation to take advantage of).
I have Bitzkrieg Commander. I used to like it because I was a Warmaster fan (it uses the same game engine) but after playing a few games and on in particular where my opponent failed on his order rolls and I managed to blast his whole army off the table with two nebelwerfers I began to realize that the command system had some issues. Then we bagan to look at how the units moved and realized that it was totally unrealistic. I now HATE BKC with a passion - consider it to be the biggest waste of my money and I have both editions. I've also played the Future War Commander which is abysmal IMHO and doesn't really convey the right feel for a future combat game.

Still - whatever floats our boats - it's all relative.
I'm looking for the following in a game,
1. simultaneous phases,
2. Doesn't require a table larger than 6 x 4 (smaller if possible) hence why I use 6mm.
3. command system - which allow for simultaneous movement.
4. Opportunity fire.
Thanks for your reply.
