On the issue of walls…

Taken from a recent discussion:

The issue of wall size comes simply from the fact that the immense hordes of walking undead will heave themselves towards our bases, piling on top of each other, until eventually (and quite unplanned by the zeds), they breach our perimeter. There is a lot of weight and force behind thousands, possibly hundreds of thousands of bodies, which should not be taken lightly. (Haha, pun!) Even if you rain lead on them, the bodies will remain to be clammered over. Higher, concrete walls give you time to burn the bodies down and away from your fortifications. They also provide you with distance from the enemy which has real effects on both physical and mental well-being. A wider, thicker wall also provides you and your defenders a more stable platform from which to fight. I wouldn’t want my men (and women) running back and forth on a 2ft wall they could easily fall from. With 5ft, you could even install guard rails/parapets, which would prevent falling, and provide weapon stabilization. Hell, with thicker walls, you can mount heavy guns. (Giggity!) You can stockpile ammo and fuel on the wall for destruction and disposal of the hordes. There is also the threat of raiders to consider. A thicker, reinforced wall gives you good protection from many forms of weapons fire, and a taller wall will provide you with your very own high ground. So when it comes to walls, sir, bigger is definitely better .
