The M12R LAAV is designed to quickly and efficiently defeat lightly armored vehicles such as Type-48 LAGC "Revenant" and Type-32 RAV "Ghost". The Rocket 'Hog is almost exactly the same in every detail to the standard M12 "Warthog" FAV except that it is equipped with a mounted M79 MLRS which fires six 65mm rockets per volley every two to three seconds.
Its rockets are capable of locking onto aircraft only. One drawback is that once you start firing you cannot stop until the rockets are all shot which can lead to friendly fire.
In campaign, it is advised that you do not leave a Rocket Warthog unattended when enemies are nearby, as Elites can get into the turret and kill you with the devastating missiles when you come back.
Written on the front-left side of the Rocket Warthog is "M/AAV-20".
A.I.'s can control the amount of missiles they can shoot and the missiles home onto all enemies (ground troops, vehicles, aircraft). However, no matter how many rockets the A.I fires, the muzzle will still flash six times.
In Rocket Hog Race the M12R's turret can be used to right the vehicle if fired with precise timing.
It seems to be a Tribute to the M12A1 LAAV or Halo CE Rocket 'hog.
