Well you would at least expect to find a side arm or ammo on a belt holster.
Or a bullet proof vest on a torso.
Or a M-16 on a dead solders body.
If a solder was on a mounted gun and died shooting.
His standard issue weapon would be near his corpse.
I could see a truck having a shovel, chains, spare gas and a tool kit.
But not a 1800's style pick axe with a wooden handle.
as for items moving from their intended place.
The survivor may have beamed to earth years after society fell.
But the rad zone suggest everyone died by high yield nuclear devices.
That everyone died swiftly quickly.
