Abandoned Camp - Bunker

He's not leaving unencumbered, is he? Because he's not leaving anything behind. Not a single damn thing. Some of this is easy. Grenades, machine gun, bullets, armor, even a few of those gasmasks can all go into the bag. The rifles, well most of those come with straps to carry them.

Assuming he's checked all the boxes, which if not, he does, he leaves a clanky, wobbly, mess.
