Based loosely on the V-2, the scud is really a terror weapon or a WMD delivery system. It has no practical conventional use. From Frontline:
The Iraqis modified Scuds for greater range, largely by reducing warhead weight, enlarging their fuel tanks and burning all of the fuel during the early phase of flight (rather than continuously). Such a Scud therefore came down with a relatively heavy warhead and a heavy motor, separated by the light empty fuel tank. It was structurally unstable and often broke up in the upper atmosphere. That further reduced its already poor accuracy…
The Iraqis basically stripped their missiles of any terminal guidance, making them utterly useless for hitting what they aimed at. But that wasn’t the point, was it?
