Aiming at base of turret as is often weak spot between turret and hull, blow turret clean off killing crew.
Not so on T-90s however.
Had the crew been better trained (or Russian) the missile would have been diverted by the laser or blown off by the explosive reactive armor - assuming boxes were not empty. 2 seconds later the TOW I (or Metis M) operator would have been dead.
TOW IIs can hit and kill T-90s according to some but they are not in theater
