marc, ficus is right. mortars have the worst pen of all gun types(even worse than rockets and normal HE, and those have horrible pin). they are lucky to go through 10 inchs of concrete(aka a bunker), MUCH LESS 16in of high quality armor. also, the cannon your basing it on has less than a 10 calibers long barrel(all morters are less than 25 calibers long), so there is not much force put into pushing the bullet(and this corisponds to a HORRIBLE pin). artillery have at least 30 calibers long, if not a lot more.
