Based on the Mirage Tank, especially its ability to assume the appearance of a tree while immobile, the Phantasm is armed with Golden Rocket launchers that can hit ground and air targets, and are mounted on a rotating turret, allowing it to fire on the move.
The Phantasm MLRS is a great unit for suprising enemy patrols as it can look like just another shrub or tree to the untrained eye. It is essentially a Mirage Tank for the Foehn Revolt and is just about as powerful with its Golden Rocket launchers. Unlike the Mirage Tank, however, it can attack aircraft and fire on the move, making it an effective counter against heavy aircraft such as the Kirov, Thor Gunship, or Basilisk.
It isn’t perfect, however. The Golden Rocket launchers, though powerful, are ineffective against infantry, just like its Allied predecessor and KEP cannon. Some things just never change, and that is why it must exercise caution when about squads of infantry.
