As a student of the Way of Saim Hann, Fritz's game winning tactics, I been confronted with a question as it relates the Tau army structure. Before we can discuss further, you have to watch this video from the genius of 40k himself.
Fritz breaks down his armies in three elements; attack, support and defense. Attack comprises an uber-unit. A unit so tough and so deadly that it can head into the heart of enemy and cause havoc amongst their ranks, allowing the rest of the army to position itself for the win. In each of his armies, it is one unit usually equipped to slug it out in close combat. The support elements have lots of fire power, are quick enough to contest objectives at the end of the game. The defense element parks on objectives on his side of the board and lays down fire.
This is a winning tactic. One I'd like to mimic. However, the Tau lack a good strong attack element. Looking at my army, I've assigned two Hammerheads and my Shas'O and Bodyguard to this role. However, they can't get too close to the enemy or it's over for them. You've got to dance your way around, laying down fire and keeping a distance. I think they might fit better as support elements. So that leads me to question whether overall Fritz tactic is something that could work for the Tau. What could fill this attack role?
I've been considering putting a unit of piranha's in this role. Five Piranhas armed with Fusion Blasters, Flachette Dischargers and Targeting Arrays. This unit could head right into the enemy, take out a tank or two, drones could detach to attack infantry. This unit turbo-boosts right in your opponents faces and threatens key targets. As your opponent works hard to take them down, your support elements, like Hammerheads and Crisis Suits, pummel your enemy from afar. They aren't rock hard but with AV 11 and 4+ cover save from moving fast, they will definitely require a serious amount of effort to take down.
I'm interested in hearing from other Tau players what unit or combination of units couple fill this type of attack role in a Tau army. What are your thoughts? Is this something Tau can do or should we be looking to have different strategy overall?
