It reminds me of some other stupid thing the military did.
In the Herens Valley, we have this unique geological oddity called the Euseigne pyramids.

Some young idiot officer thought it would be a great idea to use them as target practice...
He destroyed a bunch of them.

It is still very interesting and I recommend seeing the area.
