You are correct, attempting to rush into such a situation would quickly get you killed, even if you know what you are doing as the military presumably does, as would buttoning up and hoping your supplies outlast the horde.
However, not only is this just a topic to have fun with, not all of us think we're Rambo. Yes, the scenario I outlined above has me armed to the teeth, but if all goes well, not only would I hardly be using those weapons at all, but feeding myself won't be an issue even years down the road. I can't claim to be a combat expert, but living off the land while avoiding human contact is something I've done before, and can do again.
Frankly, if I can get past that long stretch of dangerous travel, the biggest danger i'll face is going crazy due to lack of contact.
