tactic of "dancing" and what to do about it

[tobruck41]

Panzer Campaigns and Modern all have the issue of an opponent moving in a stack (say, of tanks), fire a blast, move off, then can move in another stacks up to the hex stacking limits, fire, then also move off.

If this happens at night, or in bad weather, it is an almost impervious to harm and completely non historical.

Are there any bro rules long time gamers use to make this more fair and more historical?

Thanks
