Limit yourself - the Forgotten Unit Challenge

Every army has at least 1, some have several. What I am talking about is the unit no one plays for any number of reasons, bad model design, role duplicated in another unit, too expensive to purchase or only available for special order or just generally sucking at their intended purpose. The thing is, playing with the less than desirable units can open up some new tactics, possibly catch your opponent off guard and occasionally give you the tool needed to exploit a weakness in your opponents army. If anything it get those models that were collecting dust onto the game table where they belong.

So here is the challenge, after all what would be the fun in this exercise if we didn't set up a challenge. Build your best 1500 point list using forgotten unit for your army. Tell us the list and the tactical theme for the army. Finally play that list in a few games and let us know what worked, what was different and if you will be using that unit in a few other list based on your results.

The overlooked unit for me is the piranha. It is one of the cooler looking Tau vehicles. I love the TX-42 variant but being Forgeworld I am not including them in this build. No point in me kicking off another Forgeworld rant. The idea behind this build is to strike fast, almost like Eldar. Use the speed of the skimmers to quickly get to objectives and drop off troops so they can dig in. Then use the transports and skimmers to push back or stall the enemy to give the troops some protection. The real power of this is the piranhas speed. 6 of them in pairs can cover allot of ground without getting tied up because of squad size. Covering the rear are a pair of broadsides that are essential to making this work. They are the long range killers for stopping any mech from coming forward. The only issue is they are paired instead of being 2 independent units. It is a small price to pay though to get around the majority toughness issue. Lastly is the wild card, a lone battle suit built solely to attack objective sitters. 

So that is it. Now it is your turn. Lets see what you got.
