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
I think it depends on the series. Like the walking dead the zombies were a big the art until they learned how to deal with them. Then they became fodder and were only a the art when they had a huge wave of them.
