Come At Me, Bro!
Need some ideas for ways to sneakify your fictional world’s defenses?
Look no further than Switzerland:
From the io9 article: “To interrupt the utility of bridges, tunnels, highways, railroads, Switzerland has established three thousand points of demolition. That is the number officially printed. It has been suggested to me that to approximate a true figure a reader ought to multiply by two. Where a highway bridge crosses a railroad, a segment of the bridge is programmed to drop on the railroad. Primacord fuses are built into the bridge. Hidden artillery is in place on either side, set to prevent the enemy from clearing or repairing the damage.”
As the article rightly points out, why would Switzerland be okay with everyone knowing they have such mechanisms in place in case of foreign invasion (or a more trendy zombie apocalypse)?
Simple. If an invading force is told of even a fraction of the kind of defenses you have, especially such well-planned and craftily designed defenses, and they are told by you, it is safe for them to assume that 1) there is more waiting for them that you did not reveal, and 2) their ass is grass if they ever invade.
Now, take what Switzerland did and apply it to, say, a whole planet. What kinds of crafty shenanigans would you implement in your world to make sure you are utterly prepared to defend your population against hostile forces?
Would you weaponize your volcanoes? Build entire underground cities with networks of tunnels connecting them, including a safety mechanism to flood said tunnels in case of a breach? Would you disguise anti-aircraft missiles as trees (or hide them in trees, if your trees are big enough)? Perhaps you’d bury air force bases or flying drones underneath the sands of your desert, ready to fly at a moment’s notice. Perhaps you could harness the power of your oceans to use as a giant water gun/drill, or in the event of a no-win situation, have a plan in place to make the whole planet’s atmosphere boil or go toxic.
Tell me, how does your fictional planet/country/city/neighborhood/household defend itself?
