Master Chief with Fuel Rod Cannon substitutes as Master of the Forge with conversion beamer. He will be camping as far back as possible. I plan on using bolster defenses to put the long fangs and the Master of the Forge in prime firing position. Combined, they are going to be my main sources of anti infantry.
In larger point value games (later down the road, when I get the models) I will have Las Razorbacks to supplement this firepower. But for right now, at lower points, that's a lot of high strength templates.
