During one of the uprisings in a Soviet satellite, insurgents riveted two pie pans, face to face, and placed the empty arrangement in the road.
It stopped tank traffic for several hours, until the fake could be investigated.
It doesn't even take anything dangerous to throw sand in those gears.

I like that a lot. It will come in handy.

Somewhere I read wher that during WWII, guerrillas would dig up a dirt road in spots to make it look like something was planted there, when it wasn't - they planted the mines alongside the road where the tanks would go to bypass the obvious.

Also, when they didn't have any mines, they'd dig up the road where it bottle-necked for the purpose mentioned in the first post.

From a psyops perspective, that's pretty devious when you think about it. Do it enough, and people become lackidasical, towards possible mining. Lull them into a false sense of security, then BLAM goes the real one. You could also bury a real mine underneath a fake one. Lots of possibilities.
