@DotardTed @PawelK @sickcodes I've operated a D7 Caterpillar which is a bulldozer weighing around 14,000kg. The same model is used for clearing mines but with heavy armor. With that being said, the US has some scary antitank mines. It can sense the approach and launch into the air for a Javelin like effect. I don't know what Russia has.

The best approach that I can think of is to lay down more top soil. Perhaps it could be a Meter. It's a large task but mines don't do very well when they are buried too deep. It could keep agriculture going.
