some time ago, they used pyrite, iron sulfite, with paint to make things invisible to radar, (but to a certain point)
You'd think the armour'd deflect radar signals on it's own, but I guess they'll try anything these days....plastic tanks would work...can't hit what you can't see right?
but i can see in the report is to make the location of any troop/afv dificult to see, not to be invisible to radar, perhap with the idea of confusing the enemy troops( thinking is a mirage)
