Essentially the scud is a large slow flying bus sized contraption with a warhead on it. The patriot on the other hand is a very fast interceptor missile, travelling at about Mach 4. The guidance system works by tracking objects on radar, predicting their trajectories as if they were scuds, and if the trajectories match within a given error range the missile is launched. This would indicate that the patriot is aimed at the radar object, and fired, probably having some sort of simple radar guidance making it hone in on its target. If you wanted to find a real algorithm for intercepting missiles you could ask the people working on the US missile defence shield project, though with the results they've had you might be better off just using a quick and dirty system. Heck why not just launch several interceptor missiles and some countermeasures to boot. Then you could just roll some dice and see what did what?

Like umm, what does the US military call it? The Patriot? Somethign like that. Anyway. Can't you just get the missle to track the other missle like an AI bot walking towards a node in a path? Except in this case, it's always moving. I'm sure there are better (and more complicated) ways of doing this, but I think this should get you at least 70->80% of the way there, or make a good quick'n'dirty implementation. (or maybe I just don't understadn the problem ;)) On CivIV - just got it, havn't had a chance to play much yet. REALLY like the new menu system lay out though. The new promotions systems sounds fully sick, as does religion and governments. It's the biggest overhaul since the originals inception I think.
