After messing around for a bit, I discovered a compact way to add serious firepower to any vehicle(Let me know if this has been done, since I haven't seen it yet). By using http://www.bricklink.com/catalogItem.asp?P=30397 these beams I was able to create a 24 rocket pod, that requires only a 4x3 space on the top of a vehicle, and it has great mobility. I got the idea from the rocket pods used in the Mech Warrior series.
About this creation
This weapon system earned it's nickname "The Leveler" after demonstrating the ability to completely level any target given. Due to its adjustable firing arc, it has even been used to destroy aircraft.
