As a former soldier, I'm confident that anything they make..."joe" will break. I've never seen a piece of equipment the military made that was Joe Proof. We broke indestructible radios just by walking a few miles through the woods, I've seen spray paint ground a helicopter, I've seen waterproof electronics get fried from sweat. Just give me an example of some machine that's supposed to kill everyone, and I'll find a ridiculous way that it can be broken or rendered useless.
