We see them have backpacks or bags but rarely do we see what’s inside. They definitely don’t have clothes since they don’t change into anything. Maybe food,water,ammo but they should have more. Or sometimes there packs are too light like they don’t have anything
Crossbow bolts and modern arrows are not something you could produce more of in an apocalyptic scenario. A trad bow can use wooden arrows, but producing arrows capable of taking down large game is quite a challenge, and not something you can just go out and do in a pinch with a pocket knife and some sticks.
Arrows are reusable, but as someone who bow hunts, 100 bullets would probably last longer for me than a dozen arrows. If you miss your target, you can easily lose an arrow, or break it on a rock, break it on bone, break it by hitting your own arrow. Damaged arrows are really dangerous to try to use.
