Open topped AFV can be shot with rifles etc, from higher ground. Always been that way. Same rules as for striking top armour.

Open topped AFV have always been extremely vulnerable to infantry close assault, even if the infantry only have hand grenades.

If any aspect of an armoured vehicle is "0" armour then rifle etc. fire and shell fragments striking that face can go through. However, unlike the original SP rules, we determine actual HE penetration based on warhead size and HE pen (pen 0 and WH size 1 on armour 0 is not guaranteed (unlike SP), WH size of say 5 or so with HE pen 1 will most likely go straight through armour 0). So an AFV face with 0 armour has a little residual armour value against he pen 0 and size 1-2 shells, unlike the original SSI game.
