Bit more Scud testing completed, and they are missing their targets by about 6km or so -as if the rotation of the planet isn't being factored in or something. As such, one can simply allow for this, which does seem to work, although the accuracy of the system doesn't seem that good in game -they aren't too far off, but pin-point doesn't appear possible.
As things stand for our 'Syrian-Scuds' mission (as I have called it so I can pick it out from my missions) we now have 2 groups of 2, and each group will launch about 5 mins apart -still pondering on when to set that though.
As for the Patriot SAMs, they appear to engage the Scuds with 2 missiles and of these, about 25% seem to hit. Which IIRC, was close to what they achieved in the origianl Gulf war?
