What to do?

[PatG]

All good suggestions so far but I think the real problem is that there is no way to know in advance how much arty the other side has bought.

You get a meeting engagement, buy your forces appropriately, do your set up, maybe a turn or two of advance and - bang - the HE hurricane starts. What do you do then?

Since the opposition is artillery heavy you should have an advantage in numbers. The key would be to get onto (and off of) the objectives as efficiently as possible and nullify the artillery advantage. For infantry, scout out the enemies sight lines and move up under cover. For armour, go all out hopefully moving forward faster than the enemy can replot his fires.

In both cases, use scouts to grab VHs and pull the enemy out of position to be chewed up piecemeal. Assault through the objectives and defend from the far side to stay away from probable gold spots and to force the enemy to come to you.

Just a couple of thoughts.
