A while ago I posted about the experimental weapons Israel used in Gaza during "End Game" and how one of them, DIME appears to utilize nano-shrapnel.
Amnesty"s report mentions mm sized cubes. Is this a third type of new weapon? (Phosphorus being the third).
"They also found remnants of a new type of missile, seemingly launched from unmanned drones, which explodes large numbers of tiny sharp-edged metal cubes, each between 2mm and 4mm square in size. These lethal purpose-made shrapnel had penetrated thick metal doors and were embedded deep in concrete walls, and are clearly designed to maximize injury".
