Ah, “Ukrainian curling”…
Anti-tank mines are sometimes built so they require a significant amount of weight to detonate. Far more than what a person weighs. So… relatively safe, for an active war zone. Also, notice they only contact the sides of the mines, not the tops.
Or all of the above.
People in a war zone of that sort often have a different approach to risk than those of us living peacefully do. After being surrounded by death, destruction, and danger for a month a person’s thinking can be altered and they’ll start doing things we’d consider crazy-risky.
