Something Like That

People Guardian Unit

Probably will be some sort of Civic Unit that prevent the Ultimate Worst Case Scenario.
Like the Lightning Rod the Only may be like strike once per year. the  Light House that prevent Stupid Ship Crash, who will do that in GPS era. Yes USA Navy still do crash with most advance Equipment.

At Least Prevent some Extreme Case like Tyrant Hitler and Japan Military Warlord that ONLY Create Trouble. Really Worst Case.

No Idea or Concept. May be like some Strong-Man Look alook for the First Round of Defence.
You want to be some Tyrant, at least got to go thru some WWF Physically.
Something Like That

NB : Yes it is CIVIC Case Unofficially
