Okay, my fo' real zombie squad. This is like one'a them RPGs or something! As long as we're being creative I'll be detailed.
The Chef: This guy doesn't know the ins and outs of combating the undead, but he can whip up a good meal for you and your squadmates outta the most minuscule of ingredients. With his knowledge of food he is able to notify the other squad members of which fruits are ripe or not, whether or not that cheese has gone bad, if you should eat those tasty looking berries, and he also knows how to keep your blade sharp.
Inventory: Various portable cooking supplies, chefs knife, Glock 17 9mm pistol.
The SpecOps Guy: He can fire and maintain any gun you give him, he's physically fit, he has everything you need to survive. The SpecOps Guy's military survival training has taught him all the survival skills necessary for being in the wild, much like the chef can tell you which plants and animals are safe to eat, what they taste like, how to prepare them with little or no supplies. He and The Chef work well together, SpecOps Guy identifying edible wild plants and animals, and The Chef cooking it up to be served.
Inventory: AR-15 5.56/.223, survival knife, water canteen, various other survival goodies.
The Outdoorswoman: The Outdoorswoman is the hunter of the squad, feeling right at home inna woods. Able to hit targets with deadly accuracy and brutal efficiency. When shit hits the fan she's not afraid to club zombies brains out with the butt of her rifle, or the stab them in the socket with her bayonet. She knows how to maintain her guns very well, and is a genius at reloading spent cartridges, able to load everything from .22 to 12 gauge, and like the chef and specops guy, she is able to provide food for the rest of the squad, using her years of hunting experience to track and kill deer, and other wild animals.
Inventory:
SKS battle rifle 7.62mm, TT-33 Tokarev pistol 7.62mm, tools for gutting, skinning, and cleaning animal carcasses.
The Plinker: Prior to the apocalypse The Plinker spent his most of his time plinking with .22 caliber rifles and pistols. The .22s stopping power, or lack thereof is of no concern to The Plinker, he is able to hit the zombies right in the melon with his tacticool rifle with deadly accuracy. The Plinker is able to carry literally thousands of .22 rounds, he won't be running out anytime soon, and thanks to how little space bricks of .22 take up he also acts as a sort of pack mule, able to heft stuff the others don't have room to carry in his backpack. The Plinker was also training to become a mechanic prior to the apocalypse, but due to zombie related problems his classes were cut short, so he doesn't fully know the workings of a car, but he's still very capable of hot-wiring one, or fixing minor engine problems.
Inventory: Customized Ruger 10/22 rifle .22 LR, Ruger 22/45 pistol .22 LR, several boxes of .22 LR rounds containing 550 rounds each, some mechanic supplies.
