Static NPCs in some military vehicles/tanks

If I’m not wrong, it might be lore friendly to, at the least, find some hideaway survivor or soldier inside a tank rarely within the first week or two. That could be an interesting element to salvaging cannons and shells. You would have to wonder, when you’d open that hatch, if you’d be met with a pointed gun or a new friend…or just a tank.
