DirtSide II Rules regarding multiple targets.

Hello,
  This question is directed to the folks at GZG.  The rule books makes
it very 
clear that a vehicle can engage only one target at a time.  Specifically
it
says 
that a vehicle activated to attack an infantry unit with it's APSW
cannot make 
an attack upon other units.  I've heard of exceptions to this rule (such
as two 
fire controls etc.) on this lits but I would like an official opinion.
  Thank You,
   Phil P.
