I don't know, if we are trying to be "real" while discussing how to best slay reanimated corpses...
To be honest I resisted the idea of melee weapons, since I had a couple thousand rounds for my pistol and rifle. But "reality" set in, if this Apocalypse last more then a weekend, I maybe in trouble. If I run out of ammo, I wont be able to provide cover fire for the Chinese take out guy, and if they stop delivering my whole survival plan starts to unravel.
After watching the Walking Dead, Guns and Gardens (on youtube), 28 days later, Troy and 300, I really beginning to like the large shield idea a lot. Against slow movers, it seems that three or four shield carriers maybe able to hold off medium size groups of zed. The shield holders can push zeds back or down, while hacking away with machetes or bats (I like because they fast and light) and maybe two people behind the shield carriers with long "spear" like weapons, reaching further out killing zeds.
One shield carrier by himself, is a dead man, the shield would make him slower like the zombie and remove much of his advantage
so for shield carriers, one handed weapons, and they should of medium length so that they don't have to extend their arms out pass the shield to much, bats, machetes, any average sword,
I don't think Sledges, Picks or Axes would work (two handed), hatches and Kukris maybe not have the reach. Don't get me wrong, if you knock a zed down and walk over him and pin his neck down with your boot or shield those weapons would be perfect.
The rear people would be more spear people, but lawn darts, bows and slings would work fine. I was at home depot and the extended arm branch cutters looked cool, but they are far too flimsy to last more then a couple of hours but I like the idea. Sharp wooden stick/spear would not last long. Metal gets heavy fast
I guess my Apocalypse plans our incomplete.
