Something any (real, trained, educated) developer who has even touched AI in their career could have told you. Without a 3 month study.

Ground Control (released in 2000) had the coolest artillery units of any RTS I ever played. And I pretty much played them all. The units fired in a long ballistic trajectory that was just really awesome to watch. And IIRC massing the units and firing at a target would make the artillery blanket the area, not all just hit the same place you clicked.
