It won't prevent an RPG from penetrating the van..as the molten jet from the RPG goes about 30 meters, with lessening power, but a stand off distance of under 1meter won't protect a thin steel civilian vehicle from the hypersonic molten bullet the RPG creates, it'll cut right thru a car body easily. They'll find out soon enough
A cheaper answer: drones with a 12ga shotgun barrel and action, loaded with 00 buckshot. Nine .38 caliber rounds would be noticeable. A semiautomatic would be more effective. Or, go with an RPG warhead slung beneath the drone if light armor is suspected, a reusable flying RPG launcher.
