In the section about repair and maintaince it sites the tech level ratings for various common parts like the gyro, the ferro-fibrous armor, the cockpit, as well as putting a tech rating on the mech itself. In another example they also put a Tech Rating on an Atlas AS7-D. The TacOps only has Tech Levels for advanced components.
Where can I find Tech Levels for common components like structure, engines, heat sinks, and armor?
