Armour thickness is based on actual armor in SPMBT (taking slope into account etc). If you're referring to the mm vs cm debate (which it basically is), visit the yahoo spww2 group. It's been debated to death here.

You do realise that you can determine the range at which your units will op-fire and you can toggle weapons off to prevent them from firing? And units do tend to fire back when fired at even when the attacker is beyond the designated reaction range?
