honestly, i think bows and meele weapons would be most effective. but bows would rule cuz distance and reuseable ammo

hmmm what about Crossbows?

like even if u had a chainsaw taped to a paddle, if u tryna get to someone to chop chop, and u get an arrow to the knee, u gone. my cousin's out hunting dragons and shit, and what do i get? Guard duty!

damn you are right, what if you take actual rifles from stores that sell rifles, sure the ammo may be gone, but if you are a good enough shot, you won't need to waste bullets and if sound is a problem there can be suppressors somewhere, or do what battlefield did and fire right when it thunders.
