[SpartanTau]

PIRANHA LIGHT SKIMMER
[Dedicted to Israfel]
Good:
- access to vehicle armoury (unlike Land Speeders)
- good front armor (immune to Bolter fire)
- Seeker missile delivery system (allows Seeker Missile shots at side or rear armor within the first two turns)
- Gun Drone squadron included in points cost
- cheap upgrade to tank hunting with a Fusion Blaster
- preserving Victory Points: a squadron of two will give up no victory points if only one is destroyed during the game
- Feeding Frenzy: using multiple Fusion Piranhas to surround a transport (especially Land Raiders), destroy the transport, then prevent the squad inside from deploying, in turn destroying them as well
- only fast vehicle in the Tau arsenal
Bad:
- Open-Topped (very susceptible to ordnance, high rate of fire, etc.)
- slightly more expensive than Imperial counterparts
- can easily get very expensive
- most upgrades that are essential to the heavier Tau skimmers don't work as well with the Piranha
- hard to hide large squadrons with cover (unit footprint)

Recommendations:
Take Piranhas in squadrons of two. This way you still get a reliable and tough unit, but you can negate victory points easily. Squadrons should always be specialized (either with all Burst Cannons or with all Fusion Blasters) to maximize their potential. When used with Fusion Blasters, the drones should be disembarked soon to prevent their shots from being wasted.
If used as a Seeker Missile delivery system, use cover. The Piranhas will be the closest target, and if missiles off of them took out a Leman Russ/Predator/Falcon, your opponent will direct anti-tank weaponry against them. While they can be tough, the Piranha are still very fragile if not used correctly.
For infantry hunting, the drones should stay attached, and a squadron should advance with a Stealth Team/Kroot squad to help eliminate the threat.
