I actually thought of writing this one a while back but decided not to. Since its October I thought I would.
Now because every single 'scientific' explanation for zombies is filled with bad science. I'm saying fuck it. A bunch of idiots opened up the book of the dead and read aloud. Now Zombies have invaded the earth. You are in a group of people who banded together to survive, hunt, and gather and maybe rebuild civilization. I will go over the IDEAL gear, some of these would be near impossible to find.
What you'd want every member of the group to carry.
1. A .22 Caliber Handgun, preferably a revolver since they don't jam. You'd want it since the ammo is easy to acquire as its the most common, and after a year or two where someone would have set up a settlement. It'd be easiest to manufacture.
2. Three outfits of hiking clothes
Long sturdy pants, A sturdy shirt. wool socks. and a pair of boots This will keep you warm and it will require less patching long term
3. A Wide Brimmed Hat, I.E a cowboy hat, A Fedora (NOT A TRILBY)
Summer, Spring, and Fall you will need to keep the sun off of your face and neck.
4. Winter Gear
Coat, Hat, Gloves. It will get cold in the winter and you'll still need to hunt and gather.
5. A Cutlass
Now I've thought a while for what the ideal melee weapon would be in a zombie invasion. Its the Cutlass, You'd want some reach, so a knife is out of the question. You'd want it to be sturdy and have survival use and a cutlass is an effective way to cut through ropes and things. A cutlass is a good solid sword.
6. A hiking Backpack
7. Flint and Steel
You'll need to be able to keep warm
8. A Multi-tool
A whole lot of uses and it will help a fuckload.
9. Three waterbottles
What you'd want at least two people in the group to have
1. A Medical Kit
You will need first aid at some point and having two in the group will probably save a life.
2. A Submachine-gun
If attacked you'd want two people to be able to lay down supressing fire on these demonic zombie things.
3. A Semi-automatic Hunting Rifle
You are going to need to be able to hunt A semi-auto rifle will let you hunt at mid range.
4. A woodcutters axe and a hatchet
You'll need to be able to chop wood.
5. A survival Knife
Has a billion uses and you will probably need it.
7. Fishing Wire
8. Fishing Rods
9. Camping Cookware
You'll need to cook the food and boil water to make it drinkable.
You'll want to get passed a locked door sometime.
It will make things easier.
12. A shotgun
