20mm HE rounds?
so, instead of giving a 30mm to the IID could we give it 20mm HE rounds instead?
i think you would have a solid chance of sinking a freightor with HE rounds provided you can get in close enough. 30mm HE can punch through brick (leaving a serving platter sized hole) and a dinner plate sized hole in Re-enforced concrete, so im betting a 20mm can do almost the same.
so is 20mm HE possible and does anybody know the penetration stats?
