I can't see much getting through 20mm of hdpe but I have seen axes get through the thin sheet metal used on heavies.

Although in a heavy the batteries are likely to be further away from the walls of the bot so a weapon could never get to them. Would this rule still apply if the batteries were in the centre of the bot?
