Omnimech

Omnimechs are a clan technology that allowed stunningly fast weapon refits. In Roguetech, this capability is approximated by a fixed set of internal components. For example, the center torso of a Dire Wolf:
The gyro, engine core, engine type, and structure cannot be changed. In exchange the omnimech gyro halves the amount of time it takes to repair armor and allows weapon refits that take a single day. 
Like all default equipment, omnimech components cannot be permanently destroyed. This makes a salvaged omnimech quick and easy to field since the engine will always be repaired, not installed.
