A senior commander of the Iranian Revolutionary Guard said:
“We just used missiles that are ten years old. The era of modern missiles has not yet begun; when it does, the world will witness doomsday.”
This is true; Iran has been using their older, most outdated missiles mostly in order to deplete the US's meager remaining arsenal supply. When it is depleted, THEN we will see Iran using their most advanced missiles and drones to wipe Israel off the face of the earth. That's the plan, anyway.
