What is the definition of Civilian Project?

A 'civilian project' is like a community garden that happens in a subway tunnel during the height of the Cold War. It's a place where folks go to grow vegetables, start their own little resistance groups against the Iron Curtain, and maybe even sneak out to catch a glimpse of each other before they're caught by the watchful eyes of their fellow commuters.

Example sentence: "During the peak of the Berlin Blockade, the Berliners decided to launch their 'Civilian Project': a clandestine operation to smuggle chocolate into the city via a network of pigeon post relays, complete with coded squawks and a secret handshake."
