Re: Actung! Panzer!
if you are thinking of thew added skirts on a panzer IV H
it would be added armor only vs shape charge weapons ie(bazooka's,panzerfausts,panzersheriks,& recoiless rifles etc)
these are weapons that rely on the shaped explosive warhead to penatrate the armor as opposed to the kenitic energy poisoning generated by the volocity of the shell
the skirts predetonate the shape charge so that the real armor is beyond the focus of the jet created by the shape charge so the damage is spread over a larger area of the armor
sorry the wargaming geek got ou
