So I played my first killteam game(s) yesterday and the static gunline of firewarriors with the DS8 tactical turret is AWESOME! Especially with the smart missile system on it, you don't even need line of sight to hit your enemy.
The first game was against some dudes on bikes (space marines) and the only saving grace there was that he ended up blowing up 2 of his 5 bikers because of the Gets too hot rule. The stealth suits were able to infiltrate and pick of his leader from the back, while due to his scout move he was able to kill off most of the firewarrior carbine team but the rifle team was able to support them and inflict casualties. Ended up winning by killing off the entire team in turn 4.
Second match was tau v tau in zone mortalis. It was an objective and the opponent fielded 6 stealth suits and a team of pathfinders, while I still went with the same 3 stealth suits and 10 firewarriors with ds8 tactical turret. We traded blows, and he ended up winning after turn 5 with 5 victory points vs. my 4 with both of our leaders surviving and being inside the objective. Tau are hard to kill...
