The Piranha is a lightly armored vehicle used by the Tau in a range of capacities including rapid response, support of Pathfinder Teams, and even as battlefield transport for high-ranking dignitaries. By upgrading the vehicle to carry a Fusion Blaster or a pair of Seeker Missiles, it becomes an effective tank hunter, particularly when guided to a target by Pathfinder Teams.

You may field a Piranha Team of one to five Piranhas in your Tau army as a Fast Attack choice.
