Reactive armour needs to be attached to thick armour. If it’s attached to non-armoured things, it will do just as much damage to what it’s attached to as what it reacted to.

Any civilian truck covered with reactive armour is a death trap, and any soldier who knows anything about reactive armour will target these vehicles with the cheapest weapons that will trigger the armour. This is an example of the enemy going out of their way to get killed.

That is a practical request to help avoid damaging the rubber surface of the playground. High heels would punch holes in that surface, dramatically shortening its life, reducing its protective capabilities, and likely even twisting/snapping an ankle if the heel remains jammed in that rubber and the wearer is moving quickly.
