Penetration, armour damage et. al.

[Leutnant_von_Hausman]

Can someone explain to me how this works? There's a tooltip somewhere that explains that multiple hits to a particular region of a tank will eventually shred the armour.. How does this work?

I ask because in a multiplayer game today, playing as British, I moved my Turtle forward (which has like 200+ frontal armour) straight towards a german flak emplacement (i think it was a 38, but I'm not sure :S)

Anyway, in one volley, my turtle was destroyed. The flak took a number of shots, which I thought the turtle would shrug off, but instead it became a burnt-out, unrepairable wreck. At no point was anything but the front armour facing towards the flak (this was on canyon, going down one of the sides, so there was no opportunity for there to have been), and it was DEFINITELY the flak emplacement that killed my turtle.

Er.. what?
