Almost spit chocolate milk all over the keyboard on that one...

Seriously though, if it's real, it looks to me like a group project Darwin award in the making. For zombie attack survival, it's a one dimensional version of the Maginot Line sans artillery. This didn't work out well for the French. For "routine" survival, it looks a lot like a chimney buried underground.

Or maybe it's a plot by the government to make the survivalists easier to find and bury? (kidding! I'm just kidding! Besides, I believe all of the army's armoured D9's are in Iraq. )

Not kidding about it looking incredibly dangerous, though.
