When an A.I.-flown AH-9 targets an OPFOR vehicle with rockets at distance it continues firing them until the vehicle is destroyed, with no thought about the rockets that are already in-flight toward the target.
A.I. should fire volleys of 2, 4 or 6 rockets (variable, possibly influenced by value of the target) at a time, then wait a few seconds to see if they yield the desired result.
