Defending Switzerland
The article made reference to the extensive preparations that have been made in the event that Switz would be threatened.
Mountain bunkers & hangars
Bridges & tunnels wired with explosives
Anti-aircraft guns hidden in barns
I dug a little deeper and located more information. Some of the preparations relate back to WWII when there was concern over a German or Russian invasion.
I am not posting these links as fact, but rather as "leads" for you to do your own research.
